Overview
11 DESCRIPTION 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-dihydro-1-benzofuran-7-carboxamide monobutanedioate. The molecular formula is C 18 H 26 ClN 3 O 3 .C 4 H 6 O 4 and the molecular weight is 485.96.
Mechanism of Action
12 CLINICAL PHARMACOLOGY 12.1 Mechanism of Action Prucalopride, a selective serotonin type 4 (5-HT 4 ) 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-HT 2A , 5-HT 2B , 5-HT 3 , motilin or CCK-A receptors in vitro at concentrations exceeding 5-HT 4 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. 12.
