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.

Una pellicola multi-layered che contiene una sostanza attiva e che è fatta dei polimeri filmogeni. La pellicola contiene almeno uno strato di copertura, almeno uno strato che contengono la sostanza attiva e uno strato adesivo.
