What is prucalopride?
Prucalopride is a prescription medicine that is used to treat constipation.
MOTEGRITY (prucalopride) tablets for oral use contain prucalopride succinate, a dihydrobenzofurancarboxamide that is a serotonin type 4 (5-HT4) receptor agonist. The IUPAC name is: 4-amino-5-chloro-N-[1-(3-methoxypropyl)piperidin-4-yl]-2,3-dihydrobenzofuran-7-carboxamide succinate.
The molecular formula is C18H26ClN3O3.C4H6O4 and the molecular weight is 485.96. The structural formula is:
Prucalopride succinate is a white to almost white powder. It is highly soluble in acidic aqueous media and alkaline aqueous media up to a pH of approximately 9.
Each 1-mg film-coated tablet of MOTEGRITY contains 1 mg of prucalopride (equivalent to 1.32 mg prucalopride succinate), and the following inactive ingredients: colloidal silicon dioxide, lactose monohydrate, magnesium stearate, and microcrystalline cellulose. The coating for the 1-mg tablet contains hypromellose, lactose monohydrate, polyethylene glycol 3000, titanium dioxide, and triacetin.
Each 2-mg film-coated tablet of MOTEGRITY contains 2 mg of prucalopride (equivalent to 2.64 mg prucalopride succinate), and the following inactive ingredients: colloidal silicon dioxide, lactose monohydrate, magnesium stearate, and microcrystalline cellulose. The coating for the 2-mg tablet contains hypromellose, lactose monohydrate, polyethylene glycol 3000, titanium dioxide, triacetin, red iron oxide, yellow iron oxide, and FD&C Blue #2.
Mechanism of Action
Prucalopride, a selective serotonin type 4 (5-HT4) receptor agonist, is a gastrointestinal (GI) prokinetic agent that stimulates colonic peristalsis (high-amplitude propagating contractions [HAPCs]), which increases bowel motility.
Prucalopride was devoid of effects mediated via 5-HT2A, 5-HT2B, 5-HT3, motilin or CCK-A receptors in vitro at concentrations exceeding 5-HT4 receptor affinity by 150-fold or greater. In isolated GI tissues from various animal species, prucalopride facilitated acetylcholine release to enhance the amplitude of contractions and stimulate peristalsis. In rats and dogs, prucalopride stimulated gastrointestinal motility with contractions starting from the proximal colon to the anal sphincter.
Before taking prucalopride, tell your doctor:
- If you are allergic to prucalopride; any part of this medicine; or any other drugs, foods, or substances. Tell your doctor about the allergy and what signs you had.
- If you have any of these health problems: Bowel problems like bowel block, Crohn’s disease, hole in the GI (gastrointestinal) tract, or ulcerative colitis.
- If you have kidney disease or are on dialysis.
- If you have a rare hereditary problem of galactose intolerance, Lapp lactase deficiency, or glucose-galactose malabsorption.
This is not a list of all drugs or health problems that interact with prucalopride.
Tell your doctor and pharmacist about all of your drugs (prescription or OTC, natural products, vitamins) and health problems. You must check to make sure that it is safe for you to take prucalopride with all of your drugs and health problems. Do not start, stop, or change the dose of any drug without checking with your doctor.
