Decomposer film for transdermal patches
First Claim
1. A polymer film comprising at least one decomposer layer, wherein said at least one decomposer layer contains at least one decomposition accelerator, said decomposition accelerator being effective to decompose at least one pharmaceutical effective ingredient contained in a worn or unused transderamal patch, when an effective ingredient releasing layer of said patch adheres to the polymer film so that the pharmaceutical effective ingredient comes into contact with the decomposition accelerator by diffusion.

Abstract
The decomposer film product has a polymeric decomposer layer, a cover layer for protecting the decomposer film from the surroundings and a releasable support liner, which is removed prior to use. The polymeric decomposer film contains a water-soluble or water-insoluble polymeric adhesive material and a decomposition accelerator, which acts to decompose an effective ingredient, such as a steroid hormone, of a worn or unused transderamal patch, when the effective ingredient releasing layer of the patch adheres to the polymer film, so that the pharmaceutical effective ingredient comes into contact with the decomposition accelerator by diffusion. The decomposition accelerator includes a chemically oxidizing substance, preferably urea peroxide, manganese (III) acetate or iron (III) citrate. The water-insoluble polymeric adhesive material is preferably an acrylates adhesive. The water-soluble polymeric adhesive material is preferably polyvinyl alcohol, polyvinyl pyrrolidone, a cellulose derivative or a polyacrylic acid.
