In Vitro
In vitro Prucalopride induces contractions in a concentration-dependent manner with pEC50 of 7.5. This compound (1 mM) significantly amplifies the rebound contraction of the guinea-pig proximal colon after electrical field stimulation. It induces relaxation of the rat oesophagus preparation of rat oesophagus tunica muscularis mucosae with pEC50 of 7.8, yielding a monophasic concentration–response curve.
In Vivo
In Vivo Complete bowel movements per week is 30.9% of those receiving 2 mg of Prucalopride and 28.4% of those receiving 4 mg of this compound, as compared with 12.0% in the placebo group. 47.3% of patients receiving 2 mg of this compound and 46.6% of those receiving 4 mg of it has an increase in the number of spontaneous, complete bowel movements of one or more per week, on average, as compared with 25.8% in the placebo group. This compound (2 mg or 4 mg) significantly improves all other secondary efficacy end points, including patients' satisfaction with their bowel function and treatment and their perception of the severity of their constipation symptoms. It (4 mg daily) accelerates overall gastric emptying and small bowel transit in patients with constipation without a rectal evacuation disorder. This chemical (4 mg daily) tends to accelerate overall colonic transit with significantly faster overall colonic transit and ascending colon emptying. Higher proportions of patients on this compound 2 mg (19.5%), 4 mg (23.6%) has three or more spontaneous complete bowel movements(SCBM)/week compared with placebo (9.6%). It also significantly improves secondary efficacy and quality of life endpoints, including the proportion of patients with an increase of one or more SCBM/week, evacuation completeness, perceived disease severity and treatment effectiveness and quality of life. This compound alters colonic contractile motility patterns in a dose-dependent fashion by stimulating high-amplitude clustered contractions in the proximal colon and by inhibiting contractile activity in the distal colon of fasted dogs. It also causes a dose-dependent decrease in the time to the first giant migrating contraction (GMC); at higher doses of this chemical, the first GMC generally occurres within the first half-hour after treatment.
