Overview
Cangrelor tetrasodium, a nonthienopyridine, reversible P2Y12 platelet adenosine diphosphate (ADP)-receptor antagonist, is a platelet-activation and -aggregation inhibitor.
Cangrelor is a nonthienopyridine, direct-acting, P2Y12 ADP-receptor antagonist. Unlike the thienopyridine prodrugs clopidogrel and prasugrel but like ticagrelor, cangrelor does not require hepatic transformation to exert its pharmacologic effects. Cangrelor, like ticagrelor, binds reversibly to the P2Y12 platelet ADP receptor, preventing signal transduction of the cyclic adenosine monophosphate (cAMP) pathway.
This action results in reduced exposure of fibrinogen binding sites to the platelet glycoprotein IIb/IIIa complex and subsequent inhibition of platelet activation and aggregation.
After administration of a 30-mcg/kg IV loading dose followed by a 4-mcg/kg per minute IV infusion, peak plasma concentrations of cangrelor are reached within 2 minutes. Unlike clopidogrel, cangrelor does not require metabolic activation and as a result is not associated with interindividual variability in plasma concentrations. Cangrelor is deactivated rapidly in circulation by dephosphorylation to its primary metabolite, a nucleoside, which has negligible antiplatelet activity.
Cangrelor is eliminated principally in urine (58% of the dose) and to a lesser extent in feces (35%). Because of its short half-life (3-6 minutes) and reversible binding to the P2Y12 receptor, cangrelor has a rapid offset of effect that allows recovery of platelet function within 1 hour after cessation of IV infusion.

Contraindicated Drug Combination: This drug combination is contraindicated and generally should not be dispensed or administered to the same patient.
Anticoagulant;Antiplatelet;Thrombolytic/Alipogene Tiparvovec
SEVERITY LEVEL: 1-Contraindicated Drug Combination: This drug combination is contraindicated and generally should not be dispensed or administered to the same patient.
MECHANISM OF ACTION: Alipogene tiparvovec is given as a one-time series of intramuscular (IM)injections. Depending upon patient weight 27 to 60 injections are given, each at a different site.
CLINICAL EFFECTS: Concurrent use of anticoagulant, antiplatelet, or thrombolytic agents increase bleeding risk at IM injection sites.
PREDISPOSING FACTORS: The risk for bleeding episodes may be greater in patients with disease-associated factors (e.g. thrombocytopenia). Drug associated risk factors include concurrent use of multiple drugs which inhibit anticoagulant/antiplatelet metabolism and/or have an inherent risk for bleeding (e.g. NSAIDs).
PATIENT MANAGEMENT: Antiplatelet or other anticoagulant agents must not be taken for at least one week prior to alipogene tiparvovec therapy. Assure that abnormal bleeding parameters have been corrected prior to administration. Antiplatelet or anticoagulant therapy may be resumed one day after alipogene tiparvovec administration. If concurrent therapy is deemed medically necessary, monitor patients receiving concurrent therapy for signs of blood loss, including decreased hemoglobin, hematocrit, fecal occult blood, and/or decreased blood pressure and promptly evaluate patients with any symptoms. When applicable, perform agent-specific laboratory tests (e.g. INR, aPTT) to monitor efficacy and safety of anticoagulation. Discontinue anticoagulation in patients with active pathologic bleeding. Instruct patients to report any signs and symptoms of bleeding, such as unusual bleeding from the gums or nose; unusual bruising; red or black, tarry stools; red, pink or dark brown urine; acute abdominal or joint pain and/or swelling. The time of highest risk for a coumarin-type drug interaction is when the precipitant drug is initiated or discontinued. Contact the prescriber before initiating, altering the dose or discontinuing either drug.
DISCUSSION: Alipogene tiparvovec is given as a one-time series of intramuscular (IM)injections for the treatment of familial lipoprotein lipase deficiency. Depending upon patient weight 27 to 60 injections are given, each at a different site. Concurrent use of anticoagulant, antiplatelet, or thrombolytic agents increase bleeding risk at IM injection sites.
Anticoagulants; Antiplatelets/Mifepristone
SEVERITY LEVEL: 1-Contraindicated Drug Combination: This drug combination is contraindicated and generally should not be dispensed or administered to the same patient.
MECHANISM OF ACTION: Anticoagulants may result in excessive bleeding following the abortion.
CLINICAL EFFECTS: The concurrent use of mifepristone with anticoagulants may result in excessive bleeding following the abortion.
PREDISPOSING FACTORS: The risk for bleeding episodes may be greater in patients with disease-associated factors (e.g. thrombocytopenia). Drug associated risk factors include concurrent use of multiple drugs which inhibit anticoagulant/antiplatelet metabolism and/or have an inherent risk for bleeding (e.g. NSAIDs).
PATIENT MANAGEMENT: The manufacturer of mifepristone states that mifepristone is contraindicated in patients receiving concurrent anticoagulant therapy.(1) If concurrent therapy is deemed medically necessary, monitor patients receiving concurrent therapy for signs of blood loss, including decreased hemoglobin, hematocrit, fecal occult blood, and/or decreased blood pressure and promptly evaluate patients with any symptoms. When applicable, perform agent-specific laboratory test (e.g. INR, aPTT) to monitor efficacy and safety of anticoagulation. Discontinue anticoagulation in patients with active pathologic bleeding. Instruct patients to report any signs and symptoms of bleeding, such as unusual bleeding from the gums or nose; unusual bruising; red or black, tarry stools; red, pink or dark brown urine; acute abdominal or joint pain and/or swelling. The time of highest risk for a coumarin-type drug interaction is when the precipitant drug is initiated or discontinued. Contact the prescriber before initiating, altering the dose or discontinuing either drug.
DISCUSSION: The manufacturer of mifepristone states that mifepristone is contraindicated in patients receiving concurrent anticoagulant therapy.(1)
Severe Interaction: Action is required to reduce the risk of severe adverse interaction.
Anticoagulants; Antiplatelets/Inotersen
SEVERITY LEVEL: 2-Severe Interaction: Action is required to reduce the risk of severe adverse interaction.
MECHANISM OF ACTION: Inotersen causes reductions in platelet count that may result in sudden and unpredictable thrombocytopenia.(1)
CLINICAL EFFECTS: Concurrent use of inotersen with anticoagulants and/or antiplatelet agents may result in additive or synergistic effects, including fatal and non-fatal intracranial hemorrhage.(1)
PREDISPOSING FACTORS: The risk for bleeding episodes may also be greater in patients greater than 60 years or have a prior history of major bleeding events. Drug associated risk factors include concurrent use of multiple drugs which inhibit anticoagulant/antiplatelet metabolism and/or have an inherent risk for bleeding (e.g. NSAIDs).
PATIENT MANAGEMENT: Inotersen should be administered with caution in patients receiving anticoagulants and/or antiplatelet agents.(1) If concurrent therapy is warranted, monitor patients receiving concurrent therapy for signs of blood loss, including decreased hemoglobin, hematocrit, fecal occult blood, and/or decreased blood pressure and promptly evaluate patients with any symptoms. Monitor platelet count frequently. If platelet count is less than 50, stop inotersen treatment and consider discontinuation of any anticoagulant and/or antiplatelet agents. Monitor for signs and symptoms of thrombocytopenia; such as, unusual or prolonged bleeding (petechiae, easy bruising, hematoma, subconjunctival bleeding, gingival bleeding, epistaxis, hemoptysis, irregular or heavier than normal menstrual bleeding, hematemesis, hematuria, hematochezia, melena), neck stiffness, or atypical severe headache.
DISCUSSION: In a clinical study, platelet counts below 100 occurred in 25% of inotersen-treated patients, compared with 2% of patients on placebo. Platelet counts below 75 occurred in 14% of inotersen-treated patients, compared to no patients on placebo. In study 1 and its extension study, 39% of inotersen-treated patients with a baseline platelet count below 200 had a nadir platelet count below 75, compared to 6% of patients with baseline platelet counts 200 or higher. Three inotersen-treated patients (3%) had sudden severe thrombocytopenia (platelet count below 25). One patient experienced a fatal intracranial hemorrhage.(1) Inotersen is only available through a Tegsedi REMS program because of the risk of severe thrombocytopenia and the risk of glomerulonephritis.(1)
Anticoagulants; Antiplatelets/Tipranavir
SEVERITY LEVEL: 2-Severe Interaction: Action is required to reduce the risk of severe adverse interaction.
MECHANISM OF ACTION: Tipranavir has been shown to inhibit platelet aggregation in vitro in human platelets(1-3) and in rodents.(1,2) The mechanism behind this platelet aggregation is unknown.(1,2)
CLINICAL EFFECTS: Concurrent use of tipranavir with anticoagulants and/or antiplatelet agents may result in additive or synergistic effects, including fatal and non-fatal intracranial hemorrhage.(1-3)
PREDISPOSING FACTORS: The risk of intracranial hemorrhage may be increased by CNS lesions, head trauma, neurosurgery, coagulopathy, hypertension, or alcohol abuse.(1-3) The risk for bleeding episodes may also be greater in patients with other disease-associated factors (e.g. thrombocytopenia). Drug associated risk factors include concurrent use of multiple drugs which inhibit anticoagulant/antiplatelet metabolism and/or have an inherent risk for bleeding (e.g. NSAIDs).
PATIENT MANAGEMENT: Tipranavir should be administered with caution in patients receiving anticoagulants and/or antiplatelet agents. If concurrent therapy is warranted, monitor patients receiving concurrent therapy for signs of blood loss, including decreased hemoglobin, hematocrit, fecal occult blood, and/or decreased blood pressure and promptly evaluate patients with any symptoms. When applicable, perform agent-specific laboratory test (e.g. INR, aPTT) to monitor efficacy and safety of anticoagulation. Discontinue anticoagulation in patients with active pathologic bleeding. Patients should be warned that tipranavir has been associated with fatal and non-fatal intracranial hemorrhage and instructed to report any unusual or unexplained bleeding to their physician.(1-3) Signs or symptoms of bleeding may include unusual bleeding from the gums or nose; unusual bruising; red or black, tarry stools; red, pink or dark brown urine; acute abdominal or joint pain and/or swelling.
DISCUSSION: As of June 7, 2006,(3) the manufacturer of tipranavir has has identified 14 cases of intracranial hemorrhage, including 8 fatalities, in 13 out of 6,840 HIV+ subjects in clinical trials.(1,3) No pattern of abnormal coagulation parameters has been noted in patients receiving tipranavir in general or preceding the development of intracranial hemorrhage.(1-3) In vitro tests showed that tipranavir inhibits human platelet aggregation at concentrations consistent with normal exposure during therapy. In rodents, tipranavir resulted in increased prothrombin and activated partial thromboplastin times. At higher doses and in extreme cases, these changes resulted in bleeding in multiple organs and death. This effect was not seen in studies in dogs.(1,2)
Anticoagulants; Antiplatelets; Thrombolytics/Caplacizumab
SEVERITY LEVEL: 2-Severe Interaction: Action is required to reduce the risk of severe adverse interaction.
MECHANISM OF ACTION: Bleeding has been reported with the use of caplacizumab.(1)
CLINICAL EFFECTS: Concurrent use of caplacizumab with anticoagulants, antiplatelets, or thrombolytics may increase the risk of hemorrhage.(1)
PREDISPOSING FACTORS: The risk for bleeding episodes may be greater in patients with disease-associated factors (e.g. hemophilia, coagulation factor deficiencies). Drug associated risk factors include concurrent use of multiple drugs which inhibit anticoagulant/antiplatelet metabolism and/or have an inherent risk for bleeding (e.g. NSAIDs).
PATIENT MANAGEMENT: Avoid the use of caplacizumab with anticoagulants, antiplatelets, and thrombolytics. Interrupt caplacizumab therapy if clinically significant bleeding occurs. Patients may require von Willebrand factor concentrate to rapidly correct hemostasis. If caplacizumab is restarted, closely monitor for signs of bleeding.(1) If concurrent therapy is warranted, monitor patients receiving concurrent therapy for signs of blood loss, including decreased hemoglobin, hematocrit, fecal occult blood, and/or decreased blood pressure and promptly evaluate patients with any symptoms. When applicable, perform agent-specific laboratory tests (e.g. INR, aPTT) to monitor efficacy and safety of anticoagulation. Discontinue anticoagulation in patients with active pathologic bleeding. Instruct patients to report any signs and symptoms of bleeding, such as unusual bleeding from the gums or nose; unusual bruising; red or black, tarry stools; red, pink or dark brown urine; acute abdominal or joint pain and/or swelling. The time of highest risk for a coumarin-type drug interaction is when the precipitant drug is initiated or discontinued. Contact the prescriber before initiating, altering the dose or discontinuing either drug.
DISCUSSION: Bleeding has been reported with caplacizumab. In clinical studies, severe bleeding adverse reactions of epistaxis, gingival bleeding, upper gastrointestinal hemorrhage, and metrorrhagia were each reported in 1% of patients. Overall, bleeding events occurred in approximately 58% of patients on caplacizumab versus 43% of patients on placebo.(1) In post-marketing reports, cases of life-threatening and fatal bleeding were reported with caplacizumab.(1)
Antiplatelets; Aspirin (> 100 Mg)/Abrocitinib
SEVERITY LEVEL: 2-Severe Interaction: Action is required to reduce the risk of severe adverse interaction.
MECHANISM OF ACTION: Abrocitinib has been associated with transient, dose-dependent thrombocytopenia. The nadir platelet count occurs at a median of 24 days after receiving abrocitinib 200 mg once daily and a 40% recovery occurs by 12 weeks. Concurrent use with agents that affect platelet aggregation may result in an additive risk of bleeding.(1)
CLINICAL EFFECTS: Concurrent use of abrocitinib with antiplatelet agents may increase the risk of bleeding.(1)
PREDISPOSING FACTORS: The risk for bleeding episodes may be greater in patients with disease-associated factors (e.g. pre-existing thrombocytopenia). Abrocitinib is not recommended for patients with a platelet count less than 150,000/mm3.(1) Drug associated risk factors include concurrent use of multiple drugs which inhibit anticoagulant/antiplatelet metabolism and/or have an inherent risk for bleeding.
PATIENT MANAGEMENT: The concurrent use of abrocitinib with antiplatelet agents (except aspirin < or = 81 mg daily) is contraindicated during the first 3 months of abrocitinib therapy. Prior to starting abrocitinib therapy, obtain a complete blood count and recheck at 4 weeks after initiation and 4 weeks after a dose increase. Discontinuation of abrocitinib is required if platelets drop below 50,000/mm3.(1) If concurrent therapy is warranted after the first 3 months of abrocitinib therapy, monitor patients receiving concurrent therapy for signs of blood loss, including decreased hemoglobin, hematocrit, fecal occult blood, and/or decreased blood pressure and promptly evaluate patients with any symptoms. Instruct patients to report any signs and symptoms of bleeding, such as unusual bleeding from the gums or nose; unusual bruising; red or black, tarry stools; red, pink or dark brown urine; acute abdominal or joint pain and/or swelling.
DISCUSSION: Abrocitinib has been associated with transient, dose-dependent thrombocytopenia and is more severe with lower baseline platelet counts. At baseline platelet counts of 170,000/mm3, 220,000/m3 and 270,000/mm3, the nadirs were -41.2%, -33.4%, and -26.5%, respectively. Recovery of platelet count (about 40% recovery by 12 weeks) occurred without discontinuation of the treatment.(1)
Antiplatelets; Aspirin (> 100 Mg)/Apixaban
SEVERITY LEVEL: 2-Severe Interaction: Action is required to reduce the risk of severe adverse interaction.
MECHANISM OF ACTION: Additive effects on hemostasis.(1-4)
CLINICAL EFFECTS: Concurrent use of apixaban with antiplatelets may increase the risk of bleeding.(1-4)
PREDISPOSING FACTORS: The risk for bleeding episodes may be greater in patients with disease-associated factors (e.g. thrombocytopenia). Drug associated risk factors include concurrent use of multiple drugs which inhibit anticoagulant/antiplatelet metabolism and/or have an inherent risk for bleeding (e.g. NSAIDs).
PATIENT MANAGEMENT: Patients requiring concurrent therapy with apixaban and an antiplatelet agent should be closely monitored for signs of bleeding. Monitor patients receiving concurrent therapy for signs of blood loss, including decreased hemoglobin and/or hematocrit, fecal occult blood, and/or decreased blood pressure and promptly evaluate patients with any symptoms. When applicable, perform agent-specific laboratory test (e.g. INR, aPTT) to monitor efficacy and safety of anticoagulation. Discontinue anticoagulation in patients with active pathologic bleeding. Instruct patients to report any signs and symptoms of bleeding, such as unusual bleeding from the gums or nose; unusual bruising; red or black, tarry stools; red, pink or dark brown urine; acute abdominal or joint pain and/or swelling. Discontinue apixaban in patients with active bleeding. The time of highest risk for a coumarin-type drug interaction is when the precipitant drug is initiated or discontinued. Contact the prescriber before initiating, altering the dose or discontinuing either drug.
DISCUSSION: Concurrent administration of enoxaparin (40 mg single dose) and apixaban (5 mg single dose) resulted in additive effects on anti-Factor Xa activity.(1) Concurrent apixaban and aspirin (325 mg daily) resulted in no pharmacokinetic or pharmacodynamic interactions.(1) Concurrent apixaban with clopidogrel (75 mg daily) or with combination clopidogrel (75 mg daily) and aspirin (162 mg daily) produced no relevant increases in bleeding time, platelet aggregation, or clotting tests (PI, INR, and aPTT) compared either clopidogrel alone or clopidogrel with aspirin without apixaban.(1) Significant bleeding risk was reported with the combination of apixaban, aspirin, and clopidogrel in patients with acute coronary syndrome.(1) A self-controlled case study of 1,622 oral anticoagulant-precipitant drug pairs were reviewed and found 14% of drug pairs were associated with a statistically significant elevated risk of thromboembolism. Concurrent use of apixaban and clopidogrel resulted in a ratio of rate ratios (95% CI) of 1.96 (1.53-2.51).(5) A meta-analysis of 9 studies identified 13,459 patients taking direct oral anticoagulants (DOACs), 1,692 of whom also took an antiplatelet agent. Of the patients on antiplatelet agents, 1,254 took aspirin while the rest was unspecified. Most of the trials restricted patients to use of low-dose aspirin, with the highest allowable dose being 165 mg/day. The use of DOACs with antiplatelet agents was associated with an increased risk of major bleeding (OR 1.89; 95% CI, 1.04-3.44) and clinically relevant non-major bleeding (OR 1.82; 95% CI, 1.50-2.22). There was no difference between groups in the efficacy outcome of symptomatic recurrent venous thromboembolism (VTE) or VTE-related death.(3)
Antiplatelets; Aspirin (> 100 Mg)/Dabigatran
SEVERITY LEVEL: 2-Severe Interaction: Action is required to reduce the risk of severe adverse interaction.
MECHANISM OF ACTION: Dabigatran is a direct thrombin inhibitor and when taken with agents that effect platelet aggregation increased bleeding episodes can occur.(1,2)
CLINICAL EFFECTS: Concurrent use of dabigatran with antiplatelet agents may result in additive or synergistic effects resulting in unwanted bleeding episodes.(1,2)
PREDISPOSING FACTORS: Factors associated with an increase risk for bleeding include renal impairment, concomitant use of P-glycoprotein inhibitors, patient age >74 years, coexisting conditions (e.g. recent trauma) or use of drugs (e.g. NSAIDs) associated with bleeding risk, and patient weight <50 kg.(1-3) The risk for bleeding episodes may be greater in patients with disease-associated factors (e.g. thrombocytopenia). Drug associated risk factors include concurrent use of multiple drugs which inhibit anticoagulant/antiplatelet metabolism and/or have an inherent risk for bleeding (e.g. NSAIDs).
PATIENT MANAGEMENT: Patients requiring concurrent therapy with dabigatran and an antiplatelet agent should be closely monitored for signs of bleeding. If concurrent therapy is warranted, monitor patients receiving concurrent therapy for signs of blood loss, including decreased hemoglobin, hematocrit, fecal occult blood, and/or decreased blood pressure and promptly evaluate patients with any symptoms. When applicable, perform agent-specific laboratory test (e.g. INR, aPTT) to monitor efficacy and safety of anticoagulation. Discontinue anticoagulation in patients with active pathologic bleeding. Instruct patients to report any signs and symptoms of bleeding, such as unusual bleeding from the gums or nose; unusual bruising; red or black, tarry stools; red, pink or dark brown urine; acute abdominal or joint pain and/or swelling. The time of highest risk for a coumarin-type drug interaction is when the precipitant drug is initiated or discontinued. Contact the prescriber before initiating, altering the dose or discontinuing either drug. Discontinue dabigatran in patients with active bleeding.
DISCUSSION: Dabigatran is a direct thrombin inhibitor and when taken with agents that effect platelet aggregation and/or other clotting factors increased bleeding episodes can occur.(1,2) In the RE-LY trial, 40% of patients were on aspirin at baseline.(1) In the RE-MEDY trial, 7.7% of patients were on aspirin at baseline.(1) In the RE-DUAL PCI trial, patients were randomly assigned to one of three treatments: (A) dual therapy with dabigatran 110 mg twice daily plus either clopidogrel or ticagrelor, (B) dual therapy with dabigatran 150 mg twice daily plus either clopidogrel or ticagrelor, or (C) triple therapy with warfarin (goal INR 2-3) plus aspirin (< or = 100 mg daily) plus either clopidogrel or ticagrelor. The incidence of the first major or clinically relevant non-major (CRNM) bleeding event was 15.4% in group A compared with 26.9% in group C (hazard ratio, 0.52; 95% CI 0.42 to 0.63; p<0.001 for noninferiority; p<0.001 for superiority) and 20.2% in group B compared to 25.7% in corresponding group C (hazard ratio, 0.72; 95% CI 0.58 to 0.88; p<0.001 for noninferiority). For major bleeding as defined by Thrombolysis in Myocardial Infarction (TIMI) criteria, the rate was lower in both dual-therapy groups than in the triple-therapy group: 1.4% in group A compared to 3.8% in group C (hazard ratio, 0.37; 95% CI 0.2 to 0.68; p=0.002) and 2.1% in group B compared to 3.9% in corresponding group C (hazard ratio, 0.51; 95% CI 0.28 to 0.93; p=0.03). Incidence of composite efficacy end point of thromboembolic events (myocardial infarction, stroke, or systemic embolism), death, or unplanned revascularization was 13.7% in groups A and B compared to 13.4% in group C (hazard ratio, 1.04; 95% CI 0.84 to 1.29; p=0.005 for noninferiority).(4) A meta-analysis of 9 studies identified 13,459 patients taking direct oral anticoagulants (DOACs), 1,692 of whom also took an antiplatelet agent. Of the patients on antiplatelet agents, 1,254 took aspirin while the rest was unspecified. Most of the trials restricted patients to use of low-dose aspirin, with the highest allowable dose being 165 mg/day. Compared with DOACs alone, the use of DOACs with antiplatelet agents was associated with an increased risk of major bleeding (OR 1.89; 95% CI, 1.04-3.44) and CRNM bleeding (OR 1.82; 95% CI, 1.50-2.22). There was no difference between groups in the efficacy outcome of symptomatic recurrent venous thromboembolism (VTE) or VTE-related death.(5)
Antiplatelets; Aspirin (> 100 Mg)/Edoxaban
SEVERITY LEVEL: 2-Severe Interaction: Action is required to reduce the risk of severe adverse interaction.
MECHANISM OF ACTION: Anticoagulants and antiplatelet agents have additive effects on hemostasis.(1) In addition, aspirin doses greater than or equal to 325 mg daily increase edoxaban exposure.(1)
CLINICAL EFFECTS: Concurrent use of edoxaban with antiplatelets may increase the risk of bleeding.(1)
PREDISPOSING FACTORS: Bleeding risk may be increased in patients with renal impairment and in patients > 75 years of age.(1) Use of multiple agents which affect hemostasis increases the risk for bleeding. The risk for bleeding episodes may be greater in patient with disease-associated factors (e.g. thrombocytopenia). Drug associated risk factors include concurrent use of multiple drugs which inhibit anticoagulant/antiplatelet metabolism and/or have an inherent risk for bleeding (e.g. NSAIDs).
PATIENT MANAGEMENT: Patients requiring concurrent therapy with edoxaban and an antiplatelet agent should be closely monitored for signs of bleeding. Edoxaban and aspirin at dosages of 100 mg or less may be coadministered.(2,3) Monitor patients receiving concurrent therapy for signs of blood loss, including decreased hemoglobin and/or hematocrit, fecal occult blood, and/or decreased blood pressure and promptly evaluate patients with any symptoms. When applicable, perform agent-specific laboratory test (e.g. INR, aPTT) to monitor efficacy and safety of anticoagulation. Instruct patients to report any signs and symptoms of bleeding, such as unusual bleeding from the gums or nose; unusual bruising; red or black, tarry stools; red, pink or dark brown urine; acute abdominal or joint pain and/or swelling. Discontinue edoxaban in patients with active bleeding.
DISCUSSION: Concomitant use of edoxaban and antiplatelet agents may increase the risk of bleeding. In edoxaban clinical trials concomitant use of low dose aspirin (< or = 100 mg daily), thienopyridines, and NSAIDs was permitted and resulted in increased rates of clinically relevant bleeding. The rates of major bleeding on edoxaban and warfarin were generally consistent among subgroups. Bleeding rates appeared higher in both treatment arms (edoxaban and warfarin) in patients taking aspirin. Co-administration of aspirin (100 mg or 325 mg) and edoxaban increased bleeding time relative to that seen with either drug alone.(1) About 30% of the population in ENGAGE-AF received concomitant therapy with aspirin because of co-morbid conditions. While aspirin is known to increase risk for bleeds and the annualized event rate for major bleeds was higher than that in patients not receiving aspirin (3.87% vs. 2.13%), the risk for bleeds in patients receiving edoxaban 60 mg on a background of aspirin was lower than that for warfarin on a background of aspirin (HR 0.78 (95%CI 0.65,0.94). Based on these data no dose adjustments/contraindications are required.(4) Edoxaban and aspirin at dosages of 100 mg or less may be coadministered.(2,3) A meta-analysis of 9 studies identified 13,459 patients taking direct oral anticoagulants (DOACs), 1,692 of whom also took an antiplatelet agent. Of the patients on antiplatelet agents, 1,254 took aspirin while the rest was unspecified. Most of the trials restricted patients to use of low-dose aspirin, with the highest allowable dose being 165 mg/day. The use of DOACs with antiplatelet agents was associated with an increased risk of major bleeding (OR 1.89; 95% CI, 1.04-3.44) and clinically relevant non-major bleeding (OR 1.82; 95% CI, 1.50-2.22). There was no difference between groups in the efficacy outcome of symptomatic recurrent venous thromboembolism (VTE) or VTE-related death.(5)
Antiplatelets; Aspirin (> 325 Mg)/Betrixaban
SEVERITY LEVEL: 2-Severe Interaction: Action is required to reduce the risk of severe adverse interaction.
MECHANISM OF ACTION: Betrixaban is a factor Xa inhibitor and when taken with agents that effect platelet aggregation increased bleeding episodes can occur.(1,2)
CLINICAL EFFECTS: Concurrent use of betrixaban with antiplatelet agents may result in additive or synergistic effects resulting in unwanted bleeding episodes.(1,2)
PREDISPOSING FACTORS: Factors associated with an increase risk for bleeding include renal impairment, concomitant use of P-glycoprotein inhibitors, coexisting conditions (e.g. recent trauma) or use of drugs (e.g. NSAIDs) associated with bleeding risk.(1-3) The risk for bleeding episodes may be greater in patients with disease-associated factors (e.g. thrombocytopenia). Drug associated risk factors include concurrent use of multiple drugs which inhibit anticoagulant/antiplatelet metabolism and/or have an inherent risk for bleeding (e.g. NSAIDs).
PATIENT MANAGEMENT: Patients requiring concurrent therapy with betrixaban and an antiplatelet agent should be closely monitored for signs of bleeding. If concurrent therapy is warranted, monitor patients receiving concurrent therapy for signs of blood loss, including decreased hemoglobin, hematocrit, fecal occult blood, and/or decreased blood pressure and promptly evaluate patients with any symptoms. When applicable, perform agent-specific laboratory test (e.g. INR, aPTT) to monitor efficacy and safety of anticoagulation. Discontinue anticoagulation in patients with active pathologic bleeding. Instruct patients to report any signs and symptoms of bleeding, such as unusual bleeding from the gums or nose; unusual bruising; red or black, tarry stools; red, pink or dark brown urine; acute abdominal or joint pain and/or swelling. The time of highest risk for a coumarin-type drug interaction is when the precipitant drug is initiated or discontinued. Contact the prescriber before initiating, altering the dose or discontinuing either drug. Discontinue betrixaban in patients with active bleeding. The anticoagulant effect of betrixaban is expected to persist for at least 72 hours after the last dose.
DISCUSSION: Betrixaban is a factor Xa inhibitor and when taken with agents that effect platelet aggregation and/or other clotting factors increased bleeding episodes can occur.(1,2) In the APEX trial, if aspirin was required for cardiovascular disease, doses were limited to less than 165mg daily, with the exception of patients who were receiving aspirin for ischemic stroke or TIA indication, who could take 325mg daily. Concomitant use of aspirin and betrixaban resulted in a slightly increased incidence of major/clinically relevant non-major (CRNM) bleeding compared to those who did not use aspirin (3.7% vs. 2.89%). Concomitant use of aspirin with betrixaban resulted in an increased incidence of major bleeding twice as much as those who did not use aspirin with betrixaban (0.93% vs. 0.46%).(2) A meta-analysis of 9 studies identified 13,459 patients taking direct oral anticoagulants (DOACs), 1,692 of whom also took an antiplatelet agent. Of the patients on antiplatelet agents, 1,254 took aspirin while the rest was unspecified. Most of the trials restricted patients to use of low-dose aspirin, with the highest allowable dose being 165 mg/day. The use of DOACs with antiplatelet agents was associated with an increased risk of major bleeding (OR 1.89; 95% CI, 1.04-3.44) and CRNM bleeding (OR 1.82; 95% CI, 1.50-2.22). There was no difference between groups in the efficacy outcome of symptomatic recurrent venous thromboembolism (VTE) or VTE-related death.(3)
Selected Antiplatelets; Aspirin (> 100 Mg)/Rivaroxaban
SEVERITY LEVEL: 2-Severe Interaction: Action is required to reduce the risk of severe adverse interaction.
MECHANISM OF ACTION: Additive effects on hemostasis.(1)
CLINICAL EFFECTS: Concurrent use of rivaroxaban with anticoagulants, antiplatelets, or thrombolytics may increase the risk of bleeding.(1)
PREDISPOSING FACTORS: The risk for bleeding episodes may be greater in patients with disease-associated factors (e.g. thrombocytopenia). Drug associated risk factors include concurrent use of multiple drugs which inhibit anticoagulant/antiplatelet metabolism and/or have an inherent risk for bleeding (e.g. NSAIDs).
PATIENT MANAGEMENT: Avoid concurrent use of rivaroxaban and higher doses of aspirin unless the benefit is expected to outweigh the increased risk of bleeding. In the ROCKET AF trial, concomitant use of low dose aspirin (almost exclusively at less than or equal to 100 mg daily) was identified as an independent risk factor for bleeding.(1) If the benefit of concurrent use of rivaroxaban with other antiplatelets is expected to outweigh the increased risk of bleeding, closely monitor patients for signs or symptoms of bleeding.(1) The UK manufacturer of rivaroxaban states that rivaroxaban 2.5 mg twice daily is indicated with aspirin 75 - 100 mg with or without clopidogrel 75 mg or standard dose ticlopidine for post-acute coronary syndrome and in patients with CAD and PAD, weighing the risk for ischemic events against the bleeding risks. Long-term dual antiplatelet therapy should be avoided. Clinical monitoring is recommended throughout treatment.(2) If concurrent therapy is warranted, monitor patients receiving concurrent therapy for signs of blood loss, including decreased hemoglobin and/or hematocrit, fecal occult blood, and/or decreased blood pressure and promptly evaluate patients with any symptoms. When applicable, perform agent-specific laboratory test (e.g. INR, aPTT) to monitor efficacy and safety of anticoagulation. Discontinue anticoagulation in patients with active pathologic bleeding. Instruct patients to report any signs and symptoms of bleeding, such as unusual bleeding from the gums or nose; unusual bruising; red or black, tarry stools; red, pink or dark brown urine; acute abdominal or joint pain and/or swelling. The time of highest risk for a coumarin-type drug interaction is when the precipitant drug is initiated or discontinued. Contact the prescriber before initiating, altering the dose or discontinuing either drug.
DISCUSSION: In two clinical trials in healthy subjects, concurrent clopidogrel (300 mg loading dose, then 75 mg daily) and rivaroxaban (15 mg single dose) increased bleeding time to 45 minutes in 45% and 30% of subjects. This was twice the maximum increase in bleeding time seen with either agent alone.(1) In the ROCKET AF trial, concomitant aspirin use (almost exclusively at < or = to 100 mg daily) was identified as an independent risk factor for bleeding.(1) In a study, concurrent enoxaparin (40 mg) and rivaroxaban (10 mg) resulted in additive effects on anti-factor Xa activity with no effects on the pharmacokinetics of rivaroxaban.(1) In a study, concurrent warfarin (15 mg) and rivaroxaban (5 mg) resulted in additive effects on factor Xa inhibition and PT with no effects on the pharmacokinetics of rivaroxaban.(1) In a single dose study, there were no pharmacokinetic or pharmacodynamic interactions between rivaroxaban and aspirin.(1) A self-controlled case study of 1,622 oral anticoagulant-precipitant drug pairs were reviewed and found 14% of drug pairs were associated with a statistically significant elevated risk of thromboembolism. Concurrent use of rivaroxaban and dipyridamole resulted in a ratio of rate ratios (95% CI) of 3.49 (1.08-6.64); and rivaroxaban and aspirin ratio of rate ratios 2.19 (1.21-2.95).(3) A meta-analysis of 9 studies identified 13,459 patients taking direct oral anticoagulants (DOACs), 1,692 of whom also took an antiplatelet agent. Of the patients on antiplatelet agents, 1,254 took aspirin while the rest was unspecified. Most of the trials restricted patients to use of low-dose aspirin, with the highest allowable dose being 165 mg/day. The use of DOACs with antiplatelet agents was associated with an increased risk of major bleeding (OR 1.89; 95% CI, 1.04-3.44) and clinically relevant non-major bleeding (OR 1.82; 95% CI, 1.50-2.22). There was no difference between groups in the efficacy outcome of symptomatic recurrent venous thromboembolism (VTE) or VTE-related death.(4)
Selected Platelet Aggregation Inhibitors/Nsaids; Salicylates
SEVERITY LEVEL: 2-Severe Interaction: Action is required to reduce the risk of severe adverse interaction.
MECHANISM OF ACTION: Abciximab, cangrelor, cilostazol, clopidogrel, dipyridamole, eptifibatide, prasugrel, ticagrelor, vorapaxar and NSAIDs or salicylates inhibit platelet aggregation.
CLINICAL EFFECTS: Concurrent use of platelet aggregation inhibitors and NSAIDs or salicylates may increase the risk of bleeding.
PREDISPOSING FACTORS: The risk for bleeding episodes may be greater in patients with multiple disease-associated factors (e.g. thrombocytopenia, advanced liver disease). Drug associated risk factors include concurrent use of multiple drugs which inhibit anticoagulant/antiplatelet metabolism and/or have an inherent risk for bleeding (e.g., anticoagulants, other antiplatelets, corticosteroids, selective serotonin reuptake inhibitors (SSRIs) or serotonin-norepinephrine reuptake inhibitors (SNRIs). Risk of GI bleed may be increased in patients who are of older age, in poor health status, or who use alcohol or smoke. Risk may also be increased with longer duration of NSAID use and prior history of peptic ulcer disease and/or GI bleeding. Risk increases as the number of risk factors increases.
PATIENT MANAGEMENT: Use caution when administering platelet aggregation inhibitors with NSAIDs or salicylates.(1-5) It would be prudent to monitor patients more closely during concurrent therapy and to use the lowest NSAID or salicylate dose possible. If concurrent therapy is warranted, monitor patients for signs of blood loss, including decreased hemoglobin and/or hematocrit, fecal occult blood, and/or decreased blood pressure and promptly evaluate patients with any symptoms. When applicable, perform agent-specific laboratory test (e.g. INR, aPTT) to monitor efficacy and safety of anticoagulation. Discontinue anticoagulation in patients with active pathologic bleeding. Instruct patients to report any signs and symptoms of bleeding, such as unusual bleeding from the gums or nose; unusual bruising; red or black, tarry stools; red, pink or dark brown urine; acute abdominal or joint pain and/or swelling. The 2010 ACCF/ACG/AHA Consensus guidelines recommend the use of proton pump inhibitors (PPIs) in patients with multiple risk factors for GI bleeding who require antiplatelet therapy. However, esomeprazole and omeprazole should be avoided with clopidogrel as they are expected to reduce the effectiveness of clopidogrel. Use of other PPIs should be approached with caution, as they may reduce the effectiveness of clopidogrel.
DISCUSSION: Because of the increased risk of bleeding, caution is warranted when using this combination. In a nationwide cohort study, patients were evaluated for thromboembolic cardiovascular and clinically relevant bleeding events with concurrent antithrombotic and ongoing NSAID treatment. A total of 108,232 patients were followed for a mean of 2.3 +/- 1.8 years after diagnosis of myocardial infarction. Concomitant NSAID treatment significantly increased the risk for cardiovascular events (hazard ratio (HR) 6.96; 95% CI 6.24 - 6.77; p<0.001) and bleeding events (HR 4.08; 95% CI 3.51 - 4.73; p<0.001) compared to no NSAID treatment. NSAIDs were further evaluated and revealed the use of celecoxib (HR: 4.65; 95% CI: 3.17 to 6.82; p < 0.001, and 3.44; 95% CI: 2.20 to 5.39; p < 0.001, respectively) and meloxicam (HR: 3.03; 95% CI: 1.68 to 5.47; p < 0.001, and 2.80; 95% CI: 1.40 to 5.60; p < 0.001, respectively) had the lowest risk for cardiovascular and bleeding events, receptively.
Moderate Interaction: Assess the risk to the patient and take action as needed.
Anticoagulant;Antiplatelet;Thrombolytic/Icosapent Ethyl
SEVERITY LEVEL: 3-Moderate Interaction: Assess the risk to the patient and take action as needed.
MECHANISM OF ACTION: In vitro data suggests that fish oils can competitively inhibit cyclooxygenase which decreases synthesis of thromboxane A1 leading to a decrease in platelet aggregation.(1)
CLINICAL EFFECTS: Concurrent use of anticoagulant, antiplatelet, or thrombolytic agents increase bleeding risks.
PREDISPOSING FACTORS: The risk for bleeding episodes may be greater in patients with disease-associated factors (e.g. thrombocytopenia). Drug associated risk factors include concurrent use of multiple drugs which inhibit anticoagulant/antiplatelet metabolism and/or have an inherent risk for bleeding (e.g. NSAIDs).
PATIENT MANAGEMENT: If concurrent therapy is deemed medically necessary, monitor patients receiving concurrent therapy for signs of blood loss, including decreased hemoglobin, hematocrit, fecal occult blood, and/or decreased blood pressure and promptly evaluate patients with any symptoms. When applicable, perform agent-specific laboratory tests (e.g. INR, aPTT) to monitor efficacy and safety of anticoagulation. Discontinue anticoagulation in patients with active pathologic bleeding. Instruct patients to report any signs and symptoms of bleeding, such as unusual bleeding from the gums or nose; unusual bruising; red or black, tarry stools; red, pink or dark brown urine; acute abdominal or joint pain and/or swelling. The time of highest risk for a coumarin-type drug interaction is when the precipitant drug is initiated or discontinued. Contact the prescriber before initiating, altering the dose or discontinuing either drug.
DISCUSSION: Specific studies with icosapent ethyl and affects on bleeding risk have not been conducted. Concurrent use of anticoagulant, antiplatelet, or thrombolytic agents may increase bleeding risks by impairing platelet function and prolonging bleeding time.(1) Several case reports have shown increased bleeding time and an increased risk of adverse effects from concurrent therapy.(2,3,4) A randomized placebo controlled study of 40 people taking omega-3 fatty acids and oral anticoagulants showed a significant prolongation in bleeding time.(5)
Anticoagulants; Antiplatelets/Fruquintinib; Surufatinib
SEVERITY LEVEL: 3-Moderate Interaction: Assess the risk to the patient and take action as needed.
MECHANISM OF ACTION: Bleeding has been reported with the use of fruquintinib and surufatinib.(1,2)
CLINICAL EFFECTS: Concurrent use of fruquintinib or surufatinib with either anticoagulants or antiplatelets may increase the risk of hemorrhage.(1,2)
PREDISPOSING FACTORS: The risk for bleeding episodes may be greater in patients with disease-associated factors (e.g. thrombocytopenia). Drug associated risk factors include concurrent use of multiple drugs which inhibit anticoagulant/antiplatelet metabolism and/or have an inherent risk for bleeding (e.g. NSAIDs).
PATIENT MANAGEMENT: Patients receiving concurrent therapy with fruquintinib and anticoagulants and/or antiplatelets should be closely monitored for changes in platelet count or in International Normalized Ratio (INR). If a serious bleeding event occurs, the manufacturer recommends permanent discontinuation of fruquintinib.(1) Patients receiving concurrent therapy with surufatinib and anticoagulants and/or antiplatelets should be closely monitored for changes in platelet count or in INR.If a serious bleeding event occurs, the manufacturer recommends permanent discontinuation of surufatinib.(2) If concurrent therapy is warranted, monitor patients receiving concurrent therapy for signs of blood loss, including decreased hemoglobin, hematocrit, fecal occult blood, and/or decreased blood pressure and promptly evaluate patients with any symptoms. When applicable, perform agent-specific laboratory tests (e.g. INR, aPTT) to monitor efficacy and safety of anticoagulation. Discontinue anticoagulation in patients with active pathologic bleeding. Instruct patients to report any signs and symptoms of bleeding, such as unusual bleeding from the gums or nose; unusual bruising; red or black, tarry stools; red, pink or dark brown urine; acute abdominal or joint pain and/or swelling. The time of highest risk for a coumarin-type drug interaction is when the precipitant drug is initiated or discontinued. Contact the prescriber before initiating, altering the dose or discontinuing either drug.
DISCUSSION: Bleeding has been reported with fruquintinib in three randomized, double-blinded, placebo-controlled clinical trials. The incidence of grade 1 and grade 2 bleeding events was 28.2%, including gastrointestinal bleeding (10.9%), hematuria (10.6%), and epistaxis (7.5%). The incidence of grade 3 or higher bleeding events was 2.1% and included gastrointestinal bleeding (1.6%) and hemoptysis (0.5%).(1) Bleeding has been reported with surufatinib in clinical trials. Grade 1 and 2 bleeding events included gastrointestinal bleeding, blood in the urine, and gum bleeding. The incidence of grade 3 or greater bleeding events was 4.5%, including gastrointestinal hemorrhage (1.9%), and cerebral hemorrhage (1.1%). Fatalities due to bleeding were reported in 0.3% of patients. The incidence of permanent discontinuation due to bleeding was 2.6% and the incidence of suspension of surufatinib due to bleeding was 3.8%.(2)
Anticoagulants; Antiplatelets/Mifepristone (Cushing)
SEVERITY LEVEL: 3-Moderate Interaction: Assess the risk to the patient and take action as needed.
MECHANISM OF ACTION: Mifepristone is an antagonist at the progesterone receptor which can result in endometrium thickening, cystic dilatation of endometrial glands, or excessive vaginal bleeding. Concurrent use with anticoagulants or antiplatelets may further increase risk.
CLINICAL EFFECTS: The concurrent use of mifepristone with anticoagulants or antiplatelets may result in endometrium thickening, cystic dilatation of endometrial glands, or excessive vaginal bleeding.
PREDISPOSING FACTORS: The risk for bleeding episodes may be greater in patients with disease-associated factors (e.g. thrombocytopenia). Drug associated risk factors include concurrent use of multiple drugs which inhibit anticoagulant/antiplatelet metabolism and/or have an inherent risk for bleeding (e.g. NSAIDs).
PATIENT MANAGEMENT: The manufacturer of mifepristone states that mifepristone should be used with caution in patients receiving concurrent anticoagulant or antiplatelet therapy.(1) If concurrent therapy is deemed medically necessary, monitor patients receiving concurrent therapy for signs of blood loss, including decreased hemoglobin, hematocrit, fecal occult blood, and/or decreased blood pressure and promptly evaluate patients with any symptoms. When applicable, perform agent-specific laboratory test (e.g. INR, aPTT) to monitor efficacy and safety of anticoagulation. Discontinue anticoagulation in patients with active pathologic bleeding. Instruct patients to report any signs and symptoms of bleeding, such as unusual bleeding from the gums or nose; unusual bruising; red or black, tarry stools; red, pink or dark brown urine; acute abdominal or joint pain and/or swelling. Women experiencing vaginal bleeding during concurrent use should be referred to a gynecologist for further evaluation.
DISCUSSION: The manufacturer of mifepristone states that mifepristone should be used with caution in patients receiving concurrent anticoagulant or antiplatelet therapy.(1)
Anticoagulants; Antiplatelets/Obinutuzumab
SEVERITY LEVEL: 3-Moderate Interaction: Assess the risk to the patient and take action as needed.
MECHANISM OF ACTION: Severe and life-threatening thrombocytopenia has been reported during obinutuzumab therapy.(1) Anticoagulants and antiplatelets may have an additive risk of bleeding.
CLINICAL EFFECTS: Concurrent use of obinutuzumab with anticoagulants or antiplatelet agents may result in additive or synergistic effects, including fatal and non-fatal hemorrhage.(1)
PREDISPOSING FACTORS: The risk for bleeding episodes may be greater in patients with disease-associated factors (e.g. thrombocytopenia). Drug associated risk factors include concurrent use of multiple drugs which inhibit anticoagulant/antiplatelet metabolism and/or have an inherent risk for bleeding (e.g. NSAIDs).
PATIENT MANAGEMENT: Monitor all patients frequently for thrombocytopenia and signs of bleeding. Consider withholding concomitant anticoagulants and antiplatelets, especially during the first cycle of obinutuzumab.(1) If concurrent therapy is warranted, monitor patients receiving concurrent therapy for signs of blood loss, including decreased hemoglobin, hematocrit, fecal occult blood, and/or decreased blood pressure and promptly evaluate patients with any symptoms. When applicable, perform agent-specific laboratory test (e.g. INR, aPTT) to monitor efficacy and safety of anticoagulation. Discontinue anticoagulation in patients with active pathologic bleeding. Instruct patients to report any signs and symptoms of bleeding, such as unusual bleeding from the gums or nose; unusual bruising; red or black, tarry stools; red, pink or dark brown urine; acute abdominal or joint pain and/or swelling.

Anticoagulants; Antiplatelets/Plasminogen
SEVERITY LEVEL: 3-Moderate Interaction: Assess the risk to the patient and take action as needed.
MECHANISM OF ACTION: Bleeding has been reported with the use of plasminogen.(1)
CLINICAL EFFECTS: Concurrent use of plasminogen with either anticoagulants or antiplatelets may increase the risk of active bleeding during plasminogen therapy, including bleeding from mucosal disease-related lesions that may manifest as gastrointestinal (GI) bleeding, hemoptysis, epistaxis, vaginal bleeding, or hematuria.(1)
PREDISPOSING FACTORS: The risk for bleeding episodes may be greater in patients with disease-associated factors (e.g. thrombocytopenia). Drug associated risk factors include concurrent use of multiple drugs which inhibit anticoagulant/antiplatelet metabolism and/or have an inherent risk for bleeding (e.g. NSAIDs).
PATIENT MANAGEMENT: Patients receiving concurrent therapy with plasminogen and anticoagulants and/or antiplatelets should be closely monitored during plasminogen therapy for active bleeding from mucosal disease-related lesions, including GI bleeding, hemoptysis, epistaxis, vaginal bleeding, or hematuria.(1) Prior to initiation of treatment with plasminogen, confirm healing of lesions or wounds suspected as a source of a recent bleeding event. Monitor patients during and for 4 hours after infusion when administering plasminogen with concurrent anticoagulants, antiplatelet drugs, or other agents which may interfere with normal coagulation.(1) If patient experiences uncontrolled bleeding (defined as any gastrointestinal bleeding or bleeding from any other site that persists longer than 30 minutes), seek emergency care and discontinue plasminogen immediately.(1) If concurrent therapy is warranted, monitor patients receiving concurrent therapy for signs of blood loss, including decreased hemoglobin, hematocrit, fecal occult blood, and/or decreased blood pressure and promptly evaluate patients with any symptoms. When applicable, perform agent-specific laboratory tests (e.g. INR, aPTT) to monitor efficacy and safety of anticoagulation. Discontinue anticoagulation in patients with active pathologic bleeding. Instruct patients to report any signs and symptoms of bleeding, such as unusual bleeding from the gums or nose; unusual bruising; red or black, tarry stools; red, pink or dark brown urine; acute abdominal or joint pain and/or swelling. The time of highest risk for a coumarin-type drug interaction is when the precipitant drug is initiated or discontinued. Contact the prescriber before initiating, altering the dose or discontinuing either drug.
DISCUSSION: Plasminogen has not been studied in patients at an increased risk of bleeding. Bleeding has been reported with plasminogen in a two single-arm, open-label clinical trials as well as in compassionate use programs. The incidence of hemorrhage in patients with Plasminogen Deficiency Type 1 was 16% (3/19 patients).(1) One of the bleeding events occurred two days after receiving the second dose of plasminogen in a patient with a recent history of GI bleeding due to gastric ulcers. The patient received plasminogen through a compassionate use program and the dose was 6.6 mg/kg body weight every 2 days. Endoscopy showed multiple ulcers with one actively bleeding ulcer near the pylorus.(1)
Anticoagulants; Antiplatelets/Tisotumab
SEVERITY LEVEL: 3-Moderate Interaction: Assess the risk to the patient and take action as needed.
MECHANISM OF ACTION: Bleeding, including hemorrhage, has been reported with the use of tisotumab.(1)
CLINICAL EFFECTS: Concurrent use of tisotumab with either anticoagulants, antiplatelets, or NSAIDs may increase the risk of hemorrhage.(1)
PREDISPOSING FACTORS: The risk for bleeding episodes may be greater in patients with disease-associated factors (e.g. thrombocytopenia). Drug associated risk factors include concurrent use of multiple drugs which inhibit anticoagulant/antiplatelet metabolism and/or have an inherent risk for bleeding (e.g. NSAIDs).
PATIENT MANAGEMENT: Patients receiving concurrent therapy with tisotumab and anticoagulants, antiplatelets, and/or NSAIDs should be closely monitored for signs and symptoms of bleeding and changes in platelet count or International Normalized Ratio (INR). For patients experiencing pulmonary or central nervous system (CNS) hemorrhage, permanently discontinue tisotumab. For grade 2 or greater hemorrhage in any other location, withhold until bleeding has resolved, blood hemoglobin is stable, there is no bleeding diathesis that could increase the risk of continuing therapy, and there is no anatomical or pathologic condition that can increase the risk of hemorrhage. After resolution, either resume treatment or permanently discontinue tisotumab.(1) If concurrent therapy is warranted, monitor patients receiving concurrent therapy for signs of blood loss, including decreased hemoglobin, hematocrit, fecal occult blood, and/or decreased blood pressure and promptly evaluate patients with any symptoms. When applicable, perform agent-specific laboratory tests (e.g. INR, aPTT) to monitor efficacy and safety of anticoagulation. Discontinue anticoagulation in patients with active pathologic bleeding. Instruct patients to report any signs and symptoms of bleeding, such as unusual bleeding from the gums or nose; unusual bruising; red or black, tarry stools; red, pink or dark brown urine; acute abdominal or joint pain and/or swelling. The time of highest risk for a coumarin-type drug interaction is when the precipitant drug is initiated or discontinued. Contact the prescriber before initiating, altering the dose or discontinuing either drug.
DISCUSSION: Hemorrhage occurred in 62% of patients with cervical cancer treated with tisotumab across clinical trials. The most common all grade hemorrhage adverse reactions were epistaxis (44%), hematuria (10%), and vaginal hemorrhage (10%). Grade 3 hemorrhage occurred in 5% of patients.(1)
Anticoagulants; Antiplatelets; Thrombolytics/Drotrecogin
SEVERITY LEVEL: 3-Moderate Interaction: Assess the risk to the patient and take action as needed.
MECHANISM OF ACTION: Drotrecogin, anticoagulants, antiplatelets, and thrombolytics all affect hemostasis.(1)
CLINICAL EFFECTS: Concurrent use of drotrecogin with anticoagulants, antiplatelets, or thrombolytics, including heparin and aspirin, may increase the risk of bleeding.(1)
PREDISPOSING FACTORS: None determined.
PATIENT MANAGEMENT: Drotrecogin should be used with caution with other agents that affect hemostasis, including concurrent heparin for thrombotic or embolic events; recent administration (within 3 days) of thrombolytics; recent administration of oral anticoagulants (within 7 days) or glycoprotein IIb/IIIa inhibitors; or recent administration (within 7 days) of aspirin (greater than 650 mg daily) or other platelet inhibitors.(1) If concurrent therapy is warranted, monitor patients receiving concurrent therapy for signs of blood loss, including decreased hemoglobin, hematocrit, fecal occult blood, and/or decreased blood pressure and promptly evaluate patients with any symptoms. When applicable, perform agent-specific laboratory test (e.g. INR, aPTT) to monitor efficacy and safety of anticoagulation. Discontinue anticoagulation in patients with active pathologic bleeding. Instruct patients to report any signs and symptoms of bleeding, such as unusual bleeding from the gums or nose; unusual bruising; red or black, tarry stools; red, pink or dark brown urine; acute abdominal or joint pain and/or swelling.
DISCUSSION: Because of the increased risk of bleeding, drotrecogin should be used with caution with other agents that affect hemostasis, including concurrent heparin for thrombotic or embolic events; recent administration (within 3 days) of thrombolytics; recent administration of oral anticoagulants (within 7 days) or glycoprotein IIb/IIIa inhibitors; or recent administration (within 7 days) of aspirin (greater than 650 mg daily) or other platelet inhibitors.(1)
Antiplatelets/Donanemab
SEVERITY LEVEL: 3-Moderate Interaction: Assess the risk to the patient and take action as needed.
MECHANISM OF ACTION: Microhemorrhage has been reported with the use of donanemab. Radiographic changes on brain MRI have been noted as amyloid related imaging abnormalities-hemosiderin deposition (ARIA-H) which included microhemorrhage. In addition, intracerebral hemorrhages (ICH) greater than 1 cm in diameter have occurred in patients treated with donanemab.(1)
CLINICAL EFFECTS: Concurrent use of donanemab with antiplatelets may increase the risk of hemorrhage.(1)
PREDISPOSING FACTORS: The risk for bleeding episodes may be greater in patients with disease-associated factors (e.g. thrombocytopenia). Drug associated risk factors include concurrent use of multiple drugs which inhibit anticoagulant/antiplatelet metabolism and/or have an inherent risk for bleeding (e.g. NSAIDs).
PATIENT MANAGEMENT: Donanemab should be used with extreme caution in patients treated with antiplatelets. Evaluate the risks and benefits of concurrent use of donanemab with antiplatelets.(1) The manufacturer of donanemab recommends testing for AP0E4 status prior to initiation of treatment.(1) Use of antiplatelet agents in patients who are homozygous for the APOE4 gene, may have an increased risk of ARIA with donanemab therapy.(1-3) Patients receiving concurrent therapy with donanemab and antiplatelets should be closely monitored for signs and symptoms of bleeding and changes in platelet count.(1) If concurrent therapy is warranted, monitor patients receiving concurrent therapy for signs of microhemorrhage, including headache, nausea/vomiting, confusion, dizziness, visual disturbance, gait difficulties, and loss of coordination. General signs of blood loss include decreased hemoglobin, hematocrit, fecal occult blood, and/or decreased blood pressure and promptly evaluate patients with any symptoms. Instruct patients to report any signs and symptoms of bleeding, such as confusion, headache, dizziness, nausea, visual changes, unusual bleeding from the gums or nose; unusual bruising; red or black, tarry stools; red, pink or dark brown urine; acute abdominal or joint pain and/or swelling.
DISCUSSION: In a double-blind, placebo-controlled clinical study of 1736 participants randomized to receive donanemab (n = 860) or placebo (n = 876), donanemab was observed to increase amyloid related imaging abnormalities-hemosiderin deposition (ARIA-H), including microhemorrhage and intracerebral hemorrhage (ICH). Radiographic changes were classified as mild (<=4 new incidences), moderate (5 to 9 new incidences), or severe (10 or more new incidences). The maximum severity of ARIA-H microhemorrhage was observed as mild in 17% (143/853), moderate in 4% (34/853), and severe in 5% (40/853) of patients taking donanemab.(1) Baseline use of antithrombotic medications (aspirin, other antiplatelets, or anticoagulants) was allowed. The majority of exposures to antithrombotic medications were to aspirin. The incidence of ARIA-H was 30% (106/349) in patients taking donanemab with a concomitant antithrombotic medication within 30 days compared to 29% (148/504) who did not receive an antithrombotic within 30 days of an ARIA-H event.(1) The incidence of ICH greater than 1 cm in diameter was 0.6% (2/349 patients) in patients taking donanemab with a concomitant antithrombotic medication compared to 0.4% (2/504) in those who did not receive an antithrombotic. One fatal ICH occurred in a patient taking donanemab in the setting of focal neurologic symptoms of ARIA and the use of a thrombolytic agent.(1)
Antiplatelets/Lecanemab
SEVERITY LEVEL: 3-Moderate Interaction: Assess the risk to the patient and take action as needed.
MECHANISM OF ACTION: Microhemorrhage has been reported with the use of lecanemab. Radiographic changes on brain MRI have been noted as amyloid related imaging abnormalities-hemosiderin deposition (ARIA-H) which included microhemorrhage. In addition, intracerebral hemorrhages (ICH) greater than 1 cm in diameter have occurred in patients treated with lecanemab.(1)
CLINICAL EFFECTS: Concurrent use of lecanemab with antiplatelets may increase the risk of hemorrhage.(1)
PREDISPOSING FACTORS: The risk for bleeding episodes may be greater in patients with disease-associated factors (e.g. thrombocytopenia). Drug associated risk factors include concurrent use of multiple drugs which inhibit anticoagulant/antiplatelet metabolism and/or have an inherent risk for bleeding (e.g. NSAIDs).
PATIENT MANAGEMENT: Lecanemab should be used with extreme caution in patients treated with antiplatelets. Evaluate the risks and benefits of concurrent use of lecanemab with antiplatelets.(1) Appropriate use recommendations for lecanemab state antiplatelets may be used at standard doses if patients meet other criteria for lecanemab therapy. Use of antiplatelet agents in patients who are homozygous for the APOE4 gene may have an increased risk of ARIA with lecanemab therapy.(2) Patients receiving concurrent therapy with lecanemab and antiplatelets should be closely monitored for signs and symptoms of bleeding and changes in platelet count or International Normalized Ratio (INR).(1) If concurrent therapy is warranted, monitor patients receiving concurrent therapy for signs of microhemorrhage, including headache, nausea/vomiting, confusion, dizziness, visual disturbance, gait difficulties, and loss of coordination. General signs of blood loss include decreased hemoglobin, hematocrit, fecal occult blood, and/or decreased blood pressure and promptly evaluate patients with any symptoms. Instruct patients to report any signs and symptoms of bleeding, such as confusion, headache, dizziness, nausea, visual changes, unusual bleeding from the gums or nose; unusual bruising; red or black, tarry stools; red, pink or dark brown urine; acute abdominal or joint pain and/or swelling.
DISCUSSION: In clinical studies, lecanemab was observed to increase ARIA-H, including microhemorrhage and intracerebral hemorrhage. Radiographic changes were classified as mild (<=4 new incidences), moderate (5 to 9 new incidences), or severe (10 or more new incidences. Patients were excluded from clinical trials if taking concurrent anticoagulants or anti-platelets.(1) In Studies 1 and 2, the maximum severity of ARIA-H microhemorrhage was mild in 9% (79/898), moderate in 2% (19/898), and severe in 3% (28/898) of patients. Intracerebral hemorrhage greater than 1 cm in diameter was reported in 0.7% (6/898) of patients in Study 2 after treatment with lecanemab compared to 0.1% (1/897) on placebo. Fatal events of intracerebral hemorrhage in patients taking lecanemab have been observed.(1) In Study 2, baseline use of antithrombotic medications (aspirin, other antiplatelets, or anticoagulants) were allowed if patient was on a stable dose. Aspirin was the most common antithrombotic agent. The incidence of ICH was 0.9% (3/328 patients) in patients taking lecanemab with a concomitant antithrombotic medication at the time of the event compared to 0.6% (3/545 patients) in those who did not receive an antithrombotic. Patients taking lecanemab with an anticoagulant alone or combined with an antiplatelet medication or aspirin had an incidence of intracerebral hemorrhage of 2.5% (2/79 patients) compared to none in patients who received placebo.
Cangrelor/Clopidogrel; Prasugrel
SEVERITY LEVEL: 3-Moderate Interaction: Assess the risk to the patient and take action as needed.
MECHANISM OF ACTION: Cangrelor blocks the active metabolite of clopidogrel or prasugrel from binding to the platelet P2Y12 receptor when cangrelor occupies the receptor.(1-4)
CLINICAL EFFECTS: Doses of clopidogrel and prasugrel administered during cangrelor infusion will not be effective.(1)
PREDISPOSING FACTORS: None determined.
PATIENT MANAGEMENT: Clopidogrel and prasugrel should not be administered during the cangrelor infusion. When transitioning to clopidogrel or prasugrel, administer these agents immediately after the discontinuation of cangrelor infusion.(1)
DISCUSSION: The expected effects of loading doses of clopidogrel (600 mg) and prasugrel (60 mg) were blocked when these agents were administered during infusion of cangrelor.(1) There was no effect on loading doses of ticagrelor.(1) The active metabolite of clopidogrel or prasugrel is blocked from binding to the platelet P2Y12 receptor when cangrelor occupies the receptor.(2-4) Cangrelor is a direct, selective, and reversible P2Y12 platelet receptor inhibitor. Clopidogrel and prasugrel are irreversible P2Y12 platelet inhibitors.(1-4)
Platelet Aggregation Inhibitors/Eptifibatide
SEVERITY LEVEL: 3-Moderate Interaction: Assess the risk to the patient and take action as needed.
MECHANISM OF ACTION: Eptifibatide reversibly inhibits platelet aggregation by preventing the binding of fibrinogen, von Willebrand factor, and other adhesive ligands to GP IIb/IIIa.(1) Platelet aggregation inhibitors, such as clopidogrel, inhibit aggregation by inhibiting the binding of ADP to its platelet receptor.(2)
CLINICAL EFFECTS: Concurrent use of eptifibatide and platelet aggregation inhibitors may cause additive effects and increase the risk of bleeding.(1)
PREDISPOSING FACTORS: The risk for bleeding episodes may be greater in patients with disease-associated factors (e.g. thrombocytopenia). Drug associated risk factors include concurrent use of multiple drugs which inhibit anticoagulant/antiplatelet metabolism and/or have an inherent risk for bleeding (e.g. NSAIDs).
PATIENT MANAGEMENT: The manufacturer of eptifibatide recommends employing caution when using eptifibatide with other drugs that affect hemostasis, such as eptifibatide.(1) If concurrent therapy is warranted, monitor patients receiving concurrent therapy for signs of blood loss, including decreased hemoglobin, hematocrit, fecal occult blood, and/or decreased blood pressure and promptly evaluate patients with any symptoms. When applicable, perform agent-specific laboratory test (e.g. INR, aPTT) to monitor efficacy and safety of anticoagulation. Discontinue anticoagulation in patients with active pathologic bleeding. Instruct patients to report any signs and symptoms of bleeding, such as unusual bleeding from the gums or nose; unusual bruising; red or black, tarry stools; red, pink or dark brown urine; acute abdominal or joint pain and/or swelling.
DISCUSSION: The ESPRIT study observed the use of eptifibatide and clopidogrel or ticlopidine and found that when patients were carefully monitored there was no increase in risk of bleeding;(1) however, caution is still warranted.
Platelet Aggregation Inhibitors/Lepirudin
SEVERITY LEVEL: 3-Moderate Interaction: Assess the risk to the patient and take action as needed.
MECHANISM OF ACTION: Lepirudin is a highly specific direct inhibitor of thrombin.(1) Platelet aggregation inhibitors enhance the effects of lepirudin.
CLINICAL EFFECTS: Concurrent use of lepirudin and platelet aggregation inhibitors may increase the risk of bleeding complications and may enhance the effect of lepirudin on aPTT prolongation.(1)
PREDISPOSING FACTORS: The risk for bleeding episodes may be greater in patients with disease-associated factors (e.g. thrombocytopenia). Drug associated risk factors include concurrent use of multiple drugs which inhibit anticoagulant/antiplatelet metabolism and/or have an inherent risk for bleeding (e.g. NSAIDs).
PATIENT MANAGEMENT: The manufacturer recommends close monitoring of patients taking this combination.(1) If concurrent therapy is warranted, monitor patients receiving concurrent therapy for signs of blood loss, including decreased hemoglobin, hematocrit, fecal occult blood, and/or decreased blood pressure and promptly evaluate patients with any symptoms. When applicable, perform agent-specific laboratory test (e.g. INR, aPTT) to monitor efficacy and safety of anticoagulation. Discontinue anticoagulation in patients with active pathologic bleeding. Instruct patients to report any signs and symptoms of bleeding, such as unusual bleeding from the gums or nose; unusual bruising; red or black, tarry stools; red, pink or dark brown urine; acute abdominal or joint pain and/or swelling.
DISCUSSION: A study using lepirudin in combination with platelet aggregation inhibitors concluded that caution should be exercised when using this combination because of the increased risk of bleeding complications.(2)
Platelet Inhibitors/Selected Anticoagulants; Thrombolytics
SEVERITY LEVEL: 3-Moderate Interaction: Assess the risk to the patient and take action as needed.
MECHANISM OF ACTION: Platelet aggregation inhibitors work by irreversibly modifying the platelet ADP receptor and inhibiting the activation of GP IIb/IIIa complex.(1) Concurrent use with anticoagulants may result in additive effects on the clotting cascade.
CLINICAL EFFECTS: The concurrent use of platelet aggregation inhibitors and anticoagulants may result in an increased risk of bleeding.
PREDISPOSING FACTORS: The risk for bleeding episodes may be greater in patients with disease-associated factors (e.g. thrombocytopenia). Drug associated risk factors include concurrent use of multiple drugs which inhibit anticoagulant/antiplatelet metabolism and/or have an inherent risk for bleeding (e.g. NSAIDs).
PATIENT MANAGEMENT: Use caution when administering platelet aggregation inhibitors concurrently with anticoagulants.(1) Careful monitoring of appropriate laboratory values for the patient's anticoagulant (e.g. PTT for heparin, anti Xa levels for low-molecular weight heparins, INR for warfarin) as well as signs and symptoms of bleeding is warranted. If concurrent therapy is warranted, monitor patients receiving concurrent therapy for signs of blood loss, including decreased hemoglobin, hematocrit, fecal occult blood, and/or decreased blood pressure and promptly evaluate patients with any symptoms. When applicable, perform agent-specific laboratory test (e.g. INR, aPTT) to monitor efficacy and safety of anticoagulation. Discontinue anticoagulation in patients with active pathologic bleeding. Instruct patients to report any signs and symptoms of bleeding, such as unusual bleeding from the gums or nose; unusual bruising; red or black, tarry stools; red, pink or dark brown urine; acute abdominal or joint pain and/or swelling. The time of highest risk for a coumarin-type drug interaction is when the precipitant drug is initiated or discontinued. Contact the prescriber before initiating, altering the dose or discontinuing either drug.
DISCUSSION: Although a study in patients on long-term warfarin therapy found that the stable anticoagulation status was unaffected by concurrent clopidogrel use,(2) careful monitoring would be prudent. A self-controlled case study of 1,622 oral anticoagulant-precipitant drug pairs were reviewed and found 14% of drug pairs were associated with a statistically significant elevated risk of thromboembolism. Concurrent use of warfarin and dipyridamole resulted in a ratio of rate ratios (95% CI) of 2.07 (1.65-2.6); and warfarin and clopidogrel ratio of rate ratios 1.69 (1.56-1.84). A large systematic review was performed on 72 warfarin drug-drug interactions studies that reported on bleeding, thromboembolic events, or death. Most studies were retrospective cohorts. A meta-analysis of 38 of those studies found a higher rate of clinically significant bleeding in patients on warfarin and antiplatelets (OR=1.74; 95% CI 1.56-1.94). Increased bleeding risk was also seen in subgroup analyses with aspirin (OR=1.50; 95% CI 1.29-1.74), clopidogrel (OR=3.55; 95% CI 2.78-4.54), and aspirin plus clopidogrel or ticlopidine (OR=2.07, 95% CI 1.33-3.21).(4)
Selected Anticoagulants; Antiplatelets/Ibrutinib
SEVERITY LEVEL: 3-Moderate Interaction: Assess the risk to the patient and take action as needed.
MECHANISM OF ACTION: Ibrutinib administration lowers platelet count in the majority of patients.(1,2) In addition, ibrutinib has been shown to inhibit collagen-mediated platelet aggregation.(3-4) Bleeding has been reported with the use of ibrutinib,(1-4) anticoagulants, or antiplatelets alone.
CLINICAL EFFECTS: Concurrent use of ibrutinib with either anticoagulants or antiplatelets may increase the risk of hemorrhage.
PREDISPOSING FACTORS: The risk for bleeding episodes may be greater in patients with disease-associated factors (e.g. thrombocytopenia). Drug associated risk factors include concurrent use of multiple drugs which inhibit anticoagulant/antiplatelet metabolism and/or have an inherent risk for bleeding (e.g. NSAIDs).
PATIENT MANAGEMENT: The Canadian product monograph for ibrutinib recommends concurrent use with anticoagulants or antiplatelets should be approached with caution. If therapeutic anticoagulation is required, consider temporarily withholding ibrutinib therapy until stable anticoagulation in achieved.(2) The US prescribing information for ibrutinib states patients receiving concurrent therapy with ibrutinib and anticoagulants and/or antiplatelets should be closely monitored for changes in platelet count or in International Normalized Ratio (INR). Carefully weigh the risks vs. benefits of concurrent therapy in patients with significant thrombocytopenia. If a bleeding event occurs, follow manufacturer instructions for ibrutinib dose adjustment.(1) If concurrent therapy is warranted, monitor patients receiving concurrent therapy for signs of blood loss, including decreased hemoglobin, hematocrit, fecal occult blood, and/or decreased blood pressure and promptly evaluate patients with any symptoms. When applicable, perform agent-specific laboratory tests (e.g. INR, aPTT) to monitor efficacy and safety of anticoagulation. Discontinue anticoagulation in patients with active pathologic bleeding. Instruct patients to report any signs and symptoms of bleeding, such as unusual bleeding from the gums or nose; unusual bruising; red or black, tarry stools; red, pink or dark brown urine; acute abdominal or joint pain and/or swelling. The time of highest risk for a coumarin-type drug interaction is when the precipitant drug is initiated or discontinued. Contact the prescriber before initiating, altering the dose or discontinuing either drug.
DISCUSSION: Bleeding has been reported with ibrutinib alone.(1-3) Across 27 clinical trials, grade 3 or higher bleeding events, e.g. subdural hematoma, gastrointestinal bleeding or hematuria, have occurred in up to 4% of patients, with 0.4% fatality. Grade 3 or 4 thrombocytopenia occurred in 5-19% of patients. Bleeding events of any grade occurred in 39% of patients treated with ibrutinib.(1) Concurrent use of anticoagulants or antiplatelets has been reported to increase the risk for major bleeding. In clinical trials, major bleeding occurred in 3.1% of patients taking ibrutinib without concurrent anticoagulants or antiplatelets, 4.4% of patients on concurrent antiplatelets with or without anticoagulants, and 6.1% of patients on concurrent anticoagulants with or without antiplatelets.(1) In an open-label, phase 2 trial of patients with relapsed/refractory mantle cell lymphoma on ibrutinib, 61 patients (55%) on concurrent anticoagulants or antiplatelets had a higher rate of bleeding (69% any grade, 8% grade 3-4) than patients not on anticoagulants or antiplatelets (28% any grade, 4% grade 3-4).(5) A retrospective trial found a hazard ratio of 20 (95% CI, 2.1-200) for patients on ibrutinib with concurrent anticoagulants and antiplatelets. There was a trend towards an increased bleeding risk in patients on either anticoagulants or antiplatelets, but this was not statistically significant on multivariate analysis.(6) A case report of 2 patients with chronic lymphocytic leukemia (CLL) on ibrutinib and dabigatran demonstrated no stroke nor bleeding events during the mean 11.5 month follow-up.(7) A case report of 4 patients with lymphoproliferative disease on concurrent dabigatran and ibrutinib demonstrated no stroke nor major bleeding events. 1 patient experienced grade 2 conjunctival hemorrhage whilst on both ibrutinib and dabigatran. The anticoagulant was withheld and successfully re-initiated at a lower dose with no further bleeding events.(8)
Selected Platelet Inhibitors/Abciximab
SEVERITY LEVEL: 3-Moderate Interaction: Assess the risk to the patient and take action as needed.
MECHANISM OF ACTION: Dipyridamole, prasugrel, and ticlopidine inhibit platelet aggregation. Dipyridamole inhibits the uptake of adenosine, which increases the local concentration of adenosine and causes platelet aggregation inhibition.(1) Prasugrel irreversibly binds to the ADP receptors on platelets.(2) Ticlopidine interferes with platelet membrane function by inhibiting ADP-induced platelet-fibrinogen binding.(3) Abciximab inhibits platelet aggregation by preventing the binding of fibrinogen, von Willebrand factor, and other adhesive molecules on activated platelets.(4)
CLINICAL EFFECTS: Concurrent usage of these agents may result in an increased risk of bleeding.
PREDISPOSING FACTORS: The risk for bleeding episodes may be greater in patients with disease-associated factors (e.g. thrombocytopenia). Drug associated risk factors include concurrent use of multiple drugs which inhibit anticoagulant/antiplatelet metabolism and/or have an inherent risk for bleeding (e.g. NSAIDs).
PATIENT MANAGEMENT: It is not recommended to administer dipyridamole, ticlopidine, or prasugrel with abciximab because of the increased risk of bleeds. If concurrent therapy is warranted, monitor patients receiving concurrent therapy for signs of blood loss, including decreased hemoglobin, hematocrit, fecal occult blood, and/or decreased blood pressure and promptly evaluate patients with any symptoms. Instruct patients to report any signs and symptoms of bleeding, such as unusual bleeding from the gums or nose; unusual bruising; red or black, tarry stools; red, pink or dark brown urine; acute abdominal or joint pain and/or swelling.
DISCUSSION: A study including 21 patients taking ticlopidine and abciximab showed that ticlopidine elicited a subtle potentiation of the platelet-inhibitory capacity of abciximab.(5)
Slt Anticoagulants;Antiplatelets;Thrombolytics/Fluvoxamine
SEVERITY LEVEL: 3-Moderate Interaction: Assess the risk to the patient and take action as needed.
MECHANISM OF ACTION: Serotonin release by platelets plays a role in hemostasis.(1) Fluvoxamine may cause a decrease in serotonin reuptake by platelets, resulting in an additive risk of bleeding with anticoagulants, antiplatelets, and thrombolytics.
CLINICAL EFFECTS: Concurrent use of fluvoxamine and agents that affect coagulation may result in bleeding.
PREDISPOSING FACTORS: The risk for bleeding episodes may be greater in patients with disease-associated factors (e.g. thrombocytopenia). Renal impairment has been associated with an elevated risk of GI bleed in patients on SSRIs.(2) Drug associated risk factors include concurrent use of multiple drugs which inhibit anticoagulant/antiplatelet metabolism and/or have an inherent risk for bleeding (e.g. NSAIDs).
PATIENT MANAGEMENT: Concurrent therapy of fluvoxamine and agents that affect coagulation should be undertaken with caution. If concurrent therapy is warranted, monitor patients receiving concurrent therapy for signs of blood loss, including decreased hemoglobin, hematocrit, fecal occult blood, and/or decreased blood pressure and promptly evaluate patients with any symptoms. When applicable, perform agent-specific laboratory test (e.g. INR, aPTT, anti Factor Xa inhibition) to monitor efficacy and safety of anticoagulation. Discontinue anticoagulation in patients with active pathologic bleeding. Instruct patients to report any signs and symptoms of bleeding, such as unusual bleeding from the gums or nose; unusual bruising; red or black, tarry stools; red, pink or dark brown urine; acute abdominal or joint pain and/or swelling.
DISCUSSION: In a retrospective review of 5 years of data from the Pharmaco-Epidemiologic Prescription Database, hospitalizations for upper gastro-intestinal bleeding in antidepressant users were compared to those in non-antidepressant users. The risk of a bleed in a patient using an NSAID only based on an observed-expected ration was 4.5 and in a patient using low-dose aspirin only was 2.5. Concurrent use of a selective serotonin reuptake inhibitor with NSAIDs or low-dose aspirin increased the risk of bleeding to 12.2 and 5.2, respectively.(3) In another study, there were 16 cases of upper gastrointestinal bleeding in patients receiving concurrent therapy with selective serotonin reuptake inhibitors and NSAIDs. Adjusted relative risk of bleeding with NSAIDs, selective serotonin reuptake inhibitors, or both were 3.7, 2.6, or 15.6, respectively.(4) In a case-control study conducted in users of acenocoumarol or phenprocoumon, 1,848 patients who had been hospitalized with abnormal bleeding were each matched to 4 control patients. When patients took both a SSRI and a coumarin, an increased risk of hospitalization due to major non-gastrointestinal bleeding was observed (adjusted OR 1.7), but not due to gastrointestinal bleeding (adjusted OR 0.8).(5) A retrospective review examined patients discharged from a hospital with antiplatelet therapy following a myocardial infarction. When compared to aspirin therapy alone, both aspirin therapy with a SSRI and aspirin, clopidogrel, and SSRI therapy were associated with an increased risk of bleeding (hazard ratios 1.42 and 2.35, respectively.) Compared with dual antiplatelet therapy (aspirin and clopidogrel), use of aspirin and clopidogrel and a SSRI was also associated with increased risk of bleeding (hazard ratio 1.57).(6) In The Rotterdam Study, fluvoxamine increased the risk of over anticoagulation (hazard ratio 2.63). Paroxetine was not associated with an increased risk. There were insufficient numbers of patients taking other SSRIs to assess increased risk.(7) A self-controlled case study of 1,622 oral anticoagulant-precipitant drug pairs were reviewed and found 14% of drug pairs were associated with a statistically significant elevated risk of thromboembolism. Concurrent use of dabigatran and citalopram resulted in a ratio of rate ratios (95% CI) of 1.69 (1.11-2.57).(8)
Slt Anticoagulants;Antiplatelets;Thrombolytics/Ssris;Snris
SEVERITY LEVEL: 3-Moderate Interaction: Assess the risk to the patient and take action as needed.
MECHANISM OF ACTION: Serotonin release by platelets plays a role in hemostasis.(1,2) The increased risk of bleeding may be a result of a decrease in serotonin reuptake by platelets.
CLINICAL EFFECTS: Concurrent use of a selective serotonin reuptake inhibitor(1-6) or a serotonin-norepinephrine reuptake inhibitor(7-9) and agents that affect coagulation may result in bleeding.
PREDISPOSING FACTORS: The risk for bleeding episodes may be greater in patients with disease-associated factors (e.g. thrombocytopenia). Renal impairment has been associated with an elevated risk of GI bleed in patients on SSRIs.(15) Drug associated risk factors include concurrent use of multiple drugs which inhibit anticoagulant/antiplatelet metabolism and/or have an inherent risk for bleeding (e.g. NSAIDs).
PATIENT MANAGEMENT: Selective serotonin reuptake inhibitors(1-6) or serotonin-norepinephrine reuptake inhibitors(7-9) and agents that affect coagulation should be used concurrently with caution. If concurrent therapy is warranted, monitor patients receiving concurrent therapy for signs of blood loss, including decreased hemoglobin, hematocrit, fecal occult blood, and/or decreased blood pressure and promptly evaluate patients with any symptoms. When applicable, perform agent-specific laboratory test (e.g. INR, aPTT) to monitor efficacy and safety of anticoagulation. Discontinue anticoagulation in patients with active pathologic bleeding. Instruct patients to report any signs and symptoms of bleeding, such as unusual bleeding from the gums or nose; unusual bruising; red or black, tarry stools; red, pink or dark brown urine; acute abdominal or joint pain and/or swelling.

Concurrent use of dabigatran and citalopram resulted in a ratio of rate ratios (95% CI) of 1.69 (1.11-2.57).(16) A systematic review and meta-analysis of 22 cohort and case-controlled studies including over 1 million patients found 1.55-fold higher odds of upper gastrointestinal (GI) bleeding in SSRI users compared with non-SSRI users (95% CI, 1.35-1.78). In subgroup analyses, the risk was found to be greatest among participants taking SSRIs concurrently with NSAIDs or antiplatelet medications.(17)

Precautions
No enhanced messaging available.
Safety and efficacy of cangrelor have not been established in pediatric patients.
There are no adequate and well-controlled studies of cangrelor in pregnant women. Cangrelor did not produce malformations in animal reproduction studies and is not considered to be a teratogen. In embryofetal development studies in animals, cangrelor produced dose-related fetal growth retardation in rats and rabbits. In addition, the drug increased incidences of abortion and intrauterine losses in rabbits.
It is not known whether cangrelor is distributed into human milk. Because of the potential for serious adverse reactions to cangrelor in nursing infants, a decision should be made whether to discontinue nursing or the drug, taking into account the importance of the drug to the woman.
In the CHAMPION PHOENIX trial, 18% of the patients were 75 years of age or older. No overall differences in safety or efficacy were observed between these patients and those younger than 75 years of age.
No differences in safety or effectiveness have been identified between patients 75 years of age or older and younger patients.
