24-HOUR SUSTAINED-RELEASE METOCLOPRAMIDE

摘要

The invention relates to a sustained-release pharmaceutical composition comprising metoclopramide chlorhydrate in the form of tablets containing 30 mg of the active principle, intended for use in gastrointestinal disorders. The formulation mainly consists of a hydrophilic polymer, a hydrophobic polymer, a hydrophilic component and metoclopramide chlorhydrate. The hydrophilic polymer swells due to hydration upon contact with water, forming a layer of gel which controls the release of the active principle. The water inside the matrix dissolves the active principle which spreads towards the exterior through the layer of gel. The hydrophobic polymer displays plastic deformation properties under compression, surrounding the particles of the active principle and reducing the quantity and dimensions of the pores in the matrix structure, thereby slowing the release of the active principle. The hydrophilic component forms part of the structure of the gel layer, supporting same. The active principle is metoclopramide chlorhydrate or a pharmaceutically acceptable salt thereof.
