In vitro | Administration of prucalopride at dosages of 2/4 mg resulted in complete spontaneous bowel movements per week at rates of 30.9% and 28.4%, respectively, compared to 12.0% in the placebo group. Patients treated with 2 mg of prucalopride (47.3%) and those receiving 4 mg (46.6%) experienced an increase in the frequency of spontaneous bowel movements, with an average of one or more complete bowel movements per week, versus 25.8% in the placebo group. Prucalopride (2/4 mg) significantly enhanced other secondary efficacy endpoints, including patient satisfaction with their bowel functions and treatment, as well as their perception of the severity of constipation symptoms. At a dosage of 4 mg/day, prucalopride accelerated overall gastric emptying and small intestinal transit without causing intestinal evacuation disorders. It also sped up overall colonic transit and increased the colonic emptying rate. |
In vivo | Prucalopride (1 mM) significantly amplifies the rebound contraction of the guinea pig's proximal colon following electrical stimulation. It induces contractions in a concentration-dependent manner (pEC50: 7.5). Additionally, Prucalopride induces relaxation in the muscularis mucosae of the rat esophagus (pEC50: 7.8), demonstrating a monophasic concentration-response curve. |
