PROBLEM TO BE SOLVED: To provide an ophthalmic agent containing pranoprofen, having high light stability even in a long-term storage.SOLUTION: The ophthalmic agent is provided in which the light stability of a pranoprofen is improved by adding one or more selected from the group consisting of edetates, a citric acid, and a citrate to an aqueous solution that contains the pranoprofen and a sodium cromoglycate. The ophthalmic agent maintains a stable quality so that coloring and turbidness due to photodegradation are not caused even in the long-term storage. |
