Abstract
Non gelatin film materials e.g. films of modified cellulose materials find use as dosage forms. Substances are incorporated into the film matrix and films thus prepared may be administered really, or otherwise internally, or epidermally. The administable form may comprise a matrix which contains at least one water soluble polymer in the form of a film, in addition to at least one active ingredient, to produce a therapeutic, organoleptic or cosmetic effect.
Claims39
A method of producing a single, discrete non-gelatin film comprising:
- a) forming a non-gelatin polymeric film, with or without active ingredients incorporated therein;
- b) applying a liquid to one or more surfaces of the film, said liquid incorporating at least one active ingredient;
- and
- c) allowing the liquid applied to at least partially cure and associate with the film, to result in;
- the fluid being absorbed within the film, wholly or partially, and forming a homogeneous polymer film product.
