Overview
Deoxycholic acid is a cytolytic agent that causes focal adipocytolysis when injected into fat tissue.
Commercially available deoxycholic acid is a synthetic form of endogenous deoxycholic acid, which is a product of cholesterol metabolism and aids in the breakdown of dietary fat. When injected into fat tissue, deoxycholic acid physically destroys the lipid cell membrane, provoking a mild inflammatory response consisting of infiltration of macrophages to the area to remove cellular debris and released lipids. Albumin and tissue-associated protein attenuate the effects of deoxycholic acid, leaving skin and muscle largely unaffected.
Endogenous deoxycholic acid is also a component of bile, with most of the endogenous form being sequestered in the enterohepatic circulation loop. Plasma levels of endogenous deoxycholic acid are highly variable within and among individuals.
Deoxycholic acid is rapidly absorbed following subcutaneous injection, with peak plasma concentrations being achieved within a median of 18 minutes following a 100-mg dose of the drug in a single treatment session. Peak plasma deoxycholic acid concentrations were approximately 3 times higher than mean peak endogenous levels observed during a 24-hour baseline period. Deoxycholic acid plasma levels return to the endogenous range within 24 hours after administration of the drug.
Deoxycholic acid is extensively (98%) bound to plasma proteins. Under normal conditions, deoxycholic acid is not substantially metabolized. Following subcutaneous injection, deoxycholic acid is rapidly cleared into the endogenous bile acid pool in the enterohepatic circulation and is excreted intact in feces along with endogenous deoxycholic acid.
The pharmacokinetics of deoxycholic acid do not appear to be influenced by gender.

Today’s intelligence on Kybella
Indications
The following indications are listed for Kybella:
- Excess Submental Fat
Also known as: Submental Fullness.
Dosing
The manufacturer recommends an area-adjusted deoxycholic acid dose of 2 mg/cm2.
Up to 50 injections (0.2 mL each), or a total of 10 mL, of deoxycholic acid may be given in a single treatment session. Up to 6 single treatments may be administered at intervals of at least 1 month.
Deoxycholic acid injection should be inspected visually for particulate matter and discoloration prior to administration. Unopened vials of deoxycholic acid should be stored at 20-25degreesC, with excursions between 15 and 30degreesC permitted. Do not dilute or mix the drug with other compounds.
Prior to administration of the drug, the planned treatment area should be outlined with a surgical pen and a 1-cm injection grid should be applied to mark the injection sites.
Deoxycholic acid should be injected only within the target submental fat treatment area. To avoid injury to the marginal mandibular nerve, deoxycholic acid should not be injected above the inferior border of the mandible or within a region defined by a 1-1.5-cm line below the inferior border (from the angle of the mandible to the mentum). Injections into other tissues, such as muscle, salivary glands, and lymph nodes, should be avoided.
Using a large-bore needle, 1 mL of deoxycholic acid should be drawn into a sterile 1-mL syringe; any air bubbles in the syringe barrel should be expelled. Individuals receiving the drug should be instructed to tense the platysma. The submental fat should be pinched and, using a 30-gauge or smaller 0.5-inch needle, 0.2 mL of deoxycholic acid should be injected into the preplatysmal fat next to each of the marked injection sites (1 cm apart) by advancing the needle perpendicular to the skin. Upon withdrawal of the needle, pressure may be applied to each injection site if needed to minimize bleeding; an adhesive dressing also may be applied.
Injections that are too superficial (into the dermis) may result in skin ulceration and necrosis. The needle should not be withdrawn from the subcutaneous fat during injection as this may increase the risk of intradermal injection of the drug and potential skin ulceration.
Entry of deoxycholic acid into the postplatysmal fat should be avoided by injecting the drug at a depth approximately mid-way into the subcutaneous fat layer.
If at any time resistance is met during insertion of the needle, indicating the possibility of contact with fascial or nonfat tissue, the needle must be withdrawn to an appropriate depth before the drug is administered.
Vials of deoxycholic acid are for single use only; following administration of the intended dose, any remaining solution in the vial should be discarded.

Drug interactions
In vitro studies have shown that at clinically relevant concentrations, deoxycholic acid does not inhibit or induce cytochrome P-450 (CYP) isoenzymes.
Deoxycholic acid does not inhibit P-glycoprotein (P-gp); breast cancer resistance protein (BCRP); multidrug resistance-associated protein (MRP) 4 or MRP2; organic anion transport protein (OATP) 1B1, 2B1, or 1B3; organic cation transporter (OCT) 1 or OCT2; organic anion transporter (OAT) 1 or OAT3; sodium taurocholate co-transporting polypeptide (NTCP); or apical sodium-dependent bile acid transporter (ASBT).
Deoxycholic acid should be used with caution in patients receiving anticoagulant or antiplatelet therapy; excessive bleeding or bruising in the treatment area may occur.
There are no contraindication interactions for this drug.
There are no severe interactions for this drug.
There are no moderate interactions for this drug.
Contraindications
Deoxycholic acid is contraindicated in the presence of infection at the injection sites.
There are no contraindication contraindications for this drug.
- Dysphagia
- Increased risk of bleeding
Adverse reactions
Adverse effects reported in 2% or more of individuals receiving deoxycholic acid and more frequently than with placebo in 2 clinical trials (pooled data) include injection-site reactions (edema/swelling, hematoma/bruising, pain, numbness, erythema, induration, paresthesia, nodule, pruritus, skin tightness, skin warmth, nerve injury), headache, oropharyngeal pain, hypertension, nausea, and dysphagia.

Precautions
No enhanced messaging available.
Safety and efficacy of deoxycholic acid have not been established in individuals younger than 18 years of age; the manufacturer states that the drug is not intended for use in children or adolescents.
There are no adequate and well-controlled studies of deoxycholic acid in pregnant women. Animal reproductive studies have not shown evidence of fetal harm with subcutaneous administration of deoxycholic acid during organogenesis at doses up to 5 times the maximum recommended dose (MRHD).
Data are lacking on the presence of synthetic deoxycholic acid in human milk, the effects of the drug on the breastfed infant, or the effects of the drug on milk production. The developmental and health benefits of breast-feeding should be considered along with the mother's clinical need for deoxycholic acid and any potential adverse effects on the breastfed child from deoxycholic acid or the underlying maternal condition.
Clinical trials of deoxycholic acid did not include sufficient numbers of adults 65 years of age or older to determine whether geriatric individuals respond differently than younger individuals. Other clinical experience has not revealed age-related differences in response. The greater frequency of decreased hepatic, renal, and/or cardiac function and of concomitant disease and drug therapy in geriatric individuals also should be considered.
