ABSTRACT:
Provided is a complex comprising cisplatin encapsulated therein in a form in which a chlorine ion thereof is ligand-exchanged with a carboxyl anion of a block copolymer comprising poly(ethylene glycol)-poly(glutamic acid). This complex can be a medicinal preparation to which a novel dosage form decreased in toxicity can be applied.
