The invention proposes an original concept of viscous liquid compositions intended for the production of pasty forms with action and / or extended release for local applications. These compositions are remarkable in that the long-lasting action and / or the prolonged release of the active ingredient is obtained by the in situ formation of a matrix film with a stronger bio-adhesive power, more or less viscous and biodegradable. Thus, the subject of the invention is a viscous liquid composition with enhanced bio-adhesive power, for a local application in a pasty form with sustained release of an active principle, characterized in that it comprises at least one matrix agent, a medium of hydration of the matrix agent and at least one active ingredient. |
