To the sieved product were added 4.5 g of light anhydrous silicic acid and 4.5 g of magnesium stearate, and mixed with a DC mixer. The mixture was tableted using a 7.5 mm diameter mortar and punch to give 300 tablets, each weighing 15 Omg.

Abstract

La présente invention concerne un dérivé de la benzamide représenté par la formule générale (I), ou un sel, hydrate ou solvate de celui-ci. Le composé est utile comme agoniste du récepteur 5-HT4 pour la prévention et le traitement des affections du système nerveux central telles que la schizophrénie, les troubles de motilité des voies digestives tels que les nausées, le vomissement, la colopathie fonctionnelle, les ulcères gastriques et duodénaux, les troubles cardiaques fonctionnels tels que l'insuffisance cardiaque et les affections urologiques telles que l'obstruction des voies urinaires. Il s'avère également efficace comme principe antinociceptif.
