Abstract
A medical adhesive sheet comprising a support and an adhesive layer formed on one side of said support, wherein the adhesive layer comprises an adhesive polymer having a weight average molecular weight of not less than 2,000,000, preferably not less than 2,500,000, and at least one plasticizer compatible with said polymer. The medical adhesive sheet of the present invention simultaneously satisfies the adhesive property to the skin and low irritation property, since it can retain the plasticizer in the adhesive layer, even without a crosslinking treatment. The effects of the present invention can be exerted irrespective of the kind of functional group that the plasticizer and drug have.
