Abstract

La présente invention concerne un système de rétention gastrique pour temps de séjour prolongé. Des principes actifs sont libérés dans l'estomac ou dans le tractus gastro-intestinal. Le système selon l'invention comprend une enveloppe au moins partiellement semi-perméable, un agent générateur de gaz ou un polymère superabsorbant. La présente invention se caractérise en ce que l'unité de dosage (1) consiste en une poche contenant au moins deux chambres (2a, 2b, 2c, etc.) et dont la paroi avant (6) est l'enveloppe. Chaque chambre (2) est respectivement reliée à la chambre adjacente par une paroi intermédiaire commune (3a, 3b, 3c, etc.).
