The invention relates to novel viscous liquid compositions for producing pasty forms having a prolonged action and/or release for local applications. These compositions are characterized in that the long-lasting action and/or the prolonged release of the active substance is obtained by the in-situ formation of a matrix film having an increased bioadhesive power and being more or less viscous and biodegradable. The invention also relates to a viscous liquid composition with an increased bioadhesive power for a local application in pasty form with a prolonged release of an active substance, whereby being characterized in that it contains at least one matrix agent, a medium for hydrating the matrix agent, and at least one active substance.
