The present invention relates a novel pH sensitive polymer which exhibits pH dependant swelling / dissolution behavior. The composition is useful for taste masking of bitter drugs and also for the gastric delivery of the drugs. The said polymer comprises a hydrophobic monomer polymerized along with a basic monomer or a hydrophobic monomer polymerized along with a basic monomer and a hydrophilic monomer.

La présente invention a trait à un nouveau polymère sensible au pH présentant un comportement de gonflement/dissolution dépendant du pH. La composition est utile pour le masquage du goût de médicaments amers et également pour l'administration gastrique des médicaments. Ledit polymère comporte un monomère hydrophobe copolymérisé avec un monomère de base ou un monomère hydrophobe copolymérisé avec un monomère de base et un monomère hydrophile.
