Abstract:
A hyaluronic acid modification product includes a polymer bonded to hyaluronic acid, the polymer being polylactic acid, polyglycolic acid or lactic acid-glycolic acid copolymer, providing a drug carrier which efficiently encapsulates low molecular weight drugs and provides sustained-release over a long term, control of blood residence, is well dispersible in an aqueous solution, and has excellent biocompatibility.
