METHOD FOR STAINING INHIBITION OF DONEPEZIL-CONTAINING ADHESIVE COMPOSITION AND METHOD FOR REDUCTION OF FORMED DONEPEZIL-RELATED COMPOUNDS Russian patent published in 2012 - IPC A61K9/70 A61K47/02 A61K31/445 A61K47/22 A61P25/28 

FIELD: medicine.

SUBSTANCE: invention refers to medicine. What is described is a method for staining inhibition of an adhesive composition having a substrate and a layer of a pressure sensitive adhesive containing a pressure hardened adhesive and donepezil in the layer of the pressure sensitive adhesive; the layer of the pressure sensitive adhesive contains ascorbic acid, metal salt or ester of such, and metabisulphite metal salt. The method involves: the stage of preparing a mixture containing the pressure hardened adhesive, donepezil, ascorbic acid, metal salt or ester of such, and metabisulphite metal salt, and the stage of formation of the film of the pressure sensitive adhesive by applying the mixture on the substrate surface. Staining inhibition of the donepezil-containing adhesive composition enables implementing a natural colour appearance.

EFFECT: what is presented is the method for staining inhibition of donepezil-containing adhesive composition and the method for reduction of donepezil-related compounds.
