PURPOSE:An adhesive plaster, containing Zizyphus jujuba or/and SORISHI (a fruit of Rhamnus japonica Maxim.) in a plaster consisting of an adhesive material and the drug present stable without decomposition. CONSTITUTION:An adhesive plaster obtained by incorporating a plaster consisting of an adhesive material, e.g. acrylic material such as n-butyl (meth) acrylate, or rubber based material such as styrene-isoprene-styrene block copolymer rubber, with Zizyphus jujuba (fruit of Zizyphus vulgaris Lam. var. inermis Bynge of the family Rhamnacea) or/and SORISHI (fruit of Rhmnus japonica Maxim. of the above-mentioned family) in an amount of 0.01-20wt% for dried powder and an amount of about 1/2-1/3 based on the above-mentioned amount for hydrolyzate. A tackifier, e.g. terpenic resin, adhesive force and holding power modifier, e.g. liquid paraffin, water and emulsifying agent, etc., may be incorporated further as the third component. Since a compound containing phenolic hydroxyl group, amine based compound, etc., reduce considerably the content thereof among the drug to be incorporated, this plaster is particularly useful for formulating the above-mentioned drug.
