Rolled oral thin films having a high level of active-ingredient loading
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.
1 . A method for producing a water-soluble or water-dispersible active-ingredient-administering form comprising
(a) producing a film, suitable as oral film-administering form, having a content of active ingredient, wherein the film-administering form is present as a solid foam,
(b) activating a surface of the film produced in (a) in order to generate a tacky surface, and
(c) rolling up the film activated in (b) to form a rolled-up laminate.
2 . The method according to claim 1 , characterised in that the surface is activated and a tacky surface is generated by swelling, etching or melting of the surface.
3 . The method according to claim 1 , characterised in that the surface is activated and a tacky surface is generated by applying a self-adhering layer, wherein the self-adhering layer is formed from a water-erodible material and preferably a water-soluble or water-dispersible material.
4 . The method according to claim 1 , characterised in that the film suitable as an oral film-administering film is based on a film-forming polymer, selected from polyvinyl alcohol, polyethylene glycol, polyethylene oxide, cellulose derivatives, pullulan, gelatines, and agar.
