The present invention relates to a hyaluronic acid derivative in which an anti-inflammatory drug is bound via a covalent bond, wherein the structure of the hyaluronic acid derivative is represented by following formula (4) or (5):
HA-SP-NSAID (4)
HA-SP-DMARD (5)
wherein HA represents a hyaluronic acid chain; SP represents a spacer residue; NSAID represents a non-steroidal anti-inflammatory drug residue, DMARD represents a disease-modifying anti-rheumatic drug residue, and - represents the covalent bond, wherein the spacer binds to a carboxyl group of the hyaluronic acid via an amide bond and the anti-inflammatory drug selected from non-steroidal anti-inflammatory drugs and disease-modifying anti-rheumatic drugs binds to the spacer via an ester bond, an amide bond or a thioester bond.
