摘要：

PROBLEM TO BE SOLVED: To provide a cationic polymer gel which is capable of releasing a drug, exhibits good releasing effect even when it contains a drug having an anionic group, does not change in shape after releasing a drug, and can control the usage of a drug according to the medicinal effect of the drug used, and a polymer gel capable of sustained release of a drug, using the cationic polymer gel.

SOLUTION: The cationic polymer gel comprises a copolymer of a hydrophilic monomer, a cationic monomer, an anionic monomer, and a monomer copolymerizable with these monomers, wherein the content of the anionic monomer is 30-90 mol% based on the cationic monomer. The polymer gel capable of sustained release of a drug is made by using the cationic polymer gel.
