Abstract

La présente invention concerne un système d'administration de médicaments bioadhérents solides ou semi-solides, oralement ingérables. Il se compose d'un système eau-dans-l'huile présentant au moins deux phases. Une phase comporte un volume de 25 % à 75 % de phase hydrophile interne, et l'autre phase comporte un volume de 25 % à 75 % de phase hydrophobe externe. La phase hydrophobe externe est constituée de trois composants: a) un émulsifiant, b) un ester de glycéride et c) une substance cireuse.
