N2 - The 5-HT4 receptor agonist prucalopride is a prokinetic drug which improves colonic motility. Animal data and in vitro studies suggest that prucalopride also affects gastric and esophageal motor function. We aimed to assess the effect of prucalopride on gastric emptying, esophageal motility, and gastro-esophageal reflux in man. In this double-blind, placebo-controlled, randomized, crossover study, we included 21 healthy volunteers who received 4 mg prucalopride or placebo per day for 6 days. We performed high-resolution manometry (HRM) followed by 120-min HRM-pH-impedance monitoring after a standardized meal, ambulatory 24-h pH-impedance monitoring, and gastric emptying for solids. Prucalopride decreased (median [IQR]) total acid exposure time (3.4 [2.5-5.6] vs 1.7 [0.8-3.5] %, p < 0.05). The total number of reflux events was unaffected by prucalopride, however, the number of reflux events extending to the proximal esophagus was reduced by prucalopride (15.5 [9.8-25.5] vs 10.5 [5.3-17.5], p < 0.05). Furthermore, prucalopride improved acid clearance time (77.5 [47.8-108.8] vs 44.0 [30.0-67.8] s, p < 0.05). Prucalopride did not affect the number of transient lower esophageal sphincter (LES) relaxations or their association with reflux events. Esophageal motility and basal pressure of the LES were not affected by prucalopride. Prucalopride increased gastric emptying (T1/2 ; 32.7 [27.9-44.6] vs 49.8 [37.7-55.0] min, p < 0.05) and decreased residue after 120 min (8.8 [4.4-14.8] vs 2.7 [1.3-5.4] %, p < 0.05). Prucalopride reduces esophageal acid exposure and accelerates gastric emptying in healthy male volunteers. These findings suggest that the drug could be effective for treatment of patients with reflux disease and functional dyspepsia
