Abstract

PURPOSE: To prepare the titled medical material having excellent solubility and high releasability of drug component, leaving little drug component in the plaster, and giving low irritation to the skin, by using a substrate and a drug- containing plaster layer attached directly or indirectly to the substrate as constituent elements.
CONSTITUTION: The titled material consists of a substrate and a drug-containing plaster layer attached directly or indirectly to the substrate. The plaster layer is composed mainly of a copolymer derived from a (meth)acrylic acid ester having an ether group in the molecule (e.g. tetrahydrofurfuryl acrylate) (5W75wt%), an alkyl (meth)acrylate (e.g. n-butyl acrylate) (85W15wt%) and a polar monomer (e.g. maleic acid) (10W50wt%). The (meth)acrylic acid ester promotes the diffusional migration of the drug component in the copolymer by the electro-donative property of the ether bond in the molecule, and has high solubility of the drug component in itself, and accordingly, it can release a large amount of the dissolved drug component in a limited time interval.
