ANIONIC DRUG-CONTAINING MEDICAL DEVICE

摘要

The purpose of the present invention is to provide a medical device including a drug, which is manufactured using a polymer gel that enables the increase in the amount of the drug to be included in the medical device compared with the conventional techniques, and which has reduced influence on gel strength and shape stability after the release of the drug. The purpose can be achieved by a medical device including an anionic drug, said medical device comprising: (1) an anionic drug; and (2) a copolymer which contains, as constituent components, a cationic monomer comprising a condensation product of an alkyl quaternary ammonium compound having a substituted or unsubstituted aralkyl group and (meth)acrylic acid or a salt of the condensation product and a monomer capable of copolymerizing with the condensation product or the salt of the condensation product.
