Abstract
This invention is a water-soluble high molecular polymerized drug comprising a water-soluble clock copolymer having a hydrophilic segment and a hydrophobic pharmacological-functioning segment to side chain of which a drug is bonded. The hydrophilic first segments of the present invention include polyethylene glycol, polysaccharides, polyacrylamide, and so on. The hydrophobic segments being attached to a drug include polyaspartic acid, polyglutamic acid, polylysine, or derivatives thereof. Drugs to be attached to the hydrophobic segment include anti-cancer drugs, drugs for central nerve, drugs for circulatory organs, and so on.
