Active substance-containing multi-layer film of hydrophilic polymers crosslinked in situ

摘要

A multi-layered film which contains an active substance and which is made of film-forming polymers. The film comprises at least one covering layer, at least one layer containing the active substance, and an adhesive layer. A method and apparatus for producing such a multi-layered film and a preferred use as a transmucosal galenic formulation are also disclosed.
