Overview

Prucalopride succinate, a selective type 4 serotonin (5-HT4) receptor agonist, is a GI prokinetic agent.

Prucalopride, a selective type 4 serotonin (5-HT4) receptor agonist, is a GI prokinetic agent. The drug increases bowel motility by binding with high affinity to 5-HT4 receptors, facilitating release of acetylcholine to enhance the amplitude of contractions and stimulate colonic peristalsis. In animal studies, prucalopride has been shown to induce contractions starting from the proximal colon to the anal sphincter.

Following oral administration of a single 2-mg dose of prucalopride in patients with chronic idiopathic constipation, the number of high-amplitude propagating contractions was increased during the first 12 hours; with once-daily administration, mean colonic transit time was reduced by 12 hours from a baseline of 65 hours.

Prucalopride is devoid of effects mediated via type 2A, 2B, or 3 serotonin (5-HT2A, 5-HT2B, or 5-HT3), motilin, or cholecystokinin A receptors in vitro at concentrations exceeding the 5-HT4 receptor affinity by 150-fold or greater. In animal pharmacology studies, prucalopride had no clinically relevant effects on cardiovascular and cardiac electrophysiologic parameters at concentrations of at least 50 times the therapeutic peak plasma concentration in humans. Certain nonselective 5-HT4 receptor agonists (i.e., cisapride, tegaserod) have been associated with adverse cardiovascular events; while cardiac arrhythmias associated with cisapride use have been attributed to the drug's lack of selectivity for the 5-HT4 receptor (i.e., affinity for the human ether-a-go-go gene (hERG)-encoded cardiac potassium channel), the precise mechanism by which tegaserod use may be associated with ischemic cardiovascular events has not been fully established. (See Cardiovascular Safety under Cautions: Warnings/Precautions.)

Following oral administration, bioavailability of prucalopride exceeds 90% and peak plasma concentrations are achieved within 2-3 hours. Administration with a high-fat meal does not alter oral bioavailability. Pharmacokinetics of prucalopride are dose proportional and time independent during continued use.

The elimination half-life is approximately 1 day. The parent drug accounts for 92-94% of plasma exposure. Prucalopride is eliminated mainly by the kidneys by passive filtration and active secretion and to a lesser extent (up to 35%) by nonrenal mechanisms.

Approximately 84.2% of an orally administered dose is excreted in urine, with 60-65% of the dose excreted in urine as unchanged drug; 13.3% of an administered dose is excreted in feces, with 5% of the dose excreted in feces as unchanged drug. Prucalopride is a substrate of cytochrome P-450 (CYP) isoenzyme 3A4 in vitro. Seven minor metabolites have been identified; the most common metabolite (O-desmethylprucalopride acid) accounts for only 3.2 or 3.1% of the dose recovered in urine or feces, respectively.

Age, sex, race, and body weight (after adjustment for renal function) do not appear to affect the pharmacokinetics of prucalopride.

USES: This medication is used to treat chronic constipation. It is used when other medications used to treat constipation (such as laxatives) have not provided relief. Prucalopride works by improving how well your stomach and intestines move food through the bowels during digestion.

Indications

The following indications are listed for Motegrity:

  • Chronic Idiopathic Constipation

Dosing

Dosage of prucalopride succinate is expressed in terms of prucalopride.

For the symptomatic treatment of chronic idiopathic constipation, the recommended adult dosage of prucalopride is 2 mg once daily. In clinical trials, a dosage of 4 mg daily was not found to provide any additional benefit over the 2-mg dosage. In addition, most patients (81%) who received an initial dosage of 1 mg daily required an increase in dosage to 2 mg daily. (See Uses: Chronic Idiopathic Constipation.)

Drug interactions

There is no enhanced messaging for this drug.

Contraindications

Prucalopride is contraindicated in patients with intestinal perforation or obstruction due to a structural or functional disorder of the gut wall, obstructive ileus, or severe inflammatory conditions of the intestinal tract including Crohn's disease, ulcerative colitis, and toxic megacolon/megarectum. Prucalopride also is contraindicated in patients with known hypersensitivity to the drug.

Adverse reactions

Adverse effects reported in clinical trials in 2% or more of patients with chronic idiopathic constipation receiving prucalopride and at an incidence greater than that reported with placebo include headache, abdominal pain, nausea, diarrhea, abdominal distension, dizziness, vomiting, flatulence, and fatigue.

Precautions

No enhanced messaging available.
