摘要:
A crosslinking reaction and a reaction for reducing molecular weight that take place in a hyaluronic acid-methotrexate conjugate upon irradiation with light are suppressed to improve the photostability of the conjugate. Specifically, a substance having a quenching effect and/or a radical scaveng effect is added to a pharmaceutical composition containing the hyaluronic acid-methotrexate conjugate.
