3 g of methyl TMZ-8-carboxylate was weighed, pulverized into fine powder, and mixed with 20 g of water, 50 g of oleic acid, 30 g of VE TPGS and an appropriate amount of citric acid to form the microemulsion by grinding. An appropriate amount of rate-moderated membrane (copolymer of ethylene and vinyl acetate) and PSAs (polysiloxane pressure-sensitive gum) were added. The resulting mixture was stirred well, degassed by heat preservation using water bath, and spread on a polythene matrix. Dried and cut to 50 patches to obtain object product.
