The present invention is directed to pharmaceutical compositions, such as ophthalmic gels. The compositions typically include a carboxyvinyl polymer. A povidone polymer is also typically included to stabilize the carboxyvinyl polymer against agents or ingredients (e.g., therapeutic agent) that can otherwise cause instability to the carboxyvinyl polymer.

La présente invention porte sur des compositions pharmaceutiques, telles que des gels ophtalmiques. Les compositions comprennent typiquement un polymère carboxyvinylique. Un polymère de povidone est également typiquement inclus pour stabiliser le polymère carboxyvinylique vis-à-vis d'agents ou d'ingrédients (par exemple, un agent thérapeutique) qui peuvent sinon provoquer une instabilité du polymère carboxyvinylique.
