  • Publication number: 20240156727
    Abstract: The present invention relates to a method for producing a water-erodible, water-soluble or water-dispersible active-ingredient-administering form, in which, firstly, a film suitable as an oral film-administering form is produced which contains the active ingredient and in which a surface of the film is activated in a subsequent step in order to generate a tacky surface, followed by rolling up the activated film to form a rolled-up laminate. The present invention also relates to rolled-up laminates produced according to this method. Corresponding laminates are very stable, such that they can be dispensed and cut, and are suitable on account of their area density, which is very high by comparison with conventional OTF products, for administering active ingredients which have to be given in larger amounts.
