Synopsis: Cloteprenol is a new glucocorticoid, which can be used to treat inflammation sensitive to corticosteroids, such as eyelid and bulbar conjunctivitis, uveitis, inflammation of cornea and anterior segment. At present, the local use of glucocorticoid can significantly reduce the ocular surface inflammation, but there are many side effects, which can not be used for a long time. After eye drops, this product can be quickly metabolized into inactive products, reduce the systemic toxicity, minimize the adverse reactions of glucocorticoid, and its anti-inflammatory effect is stronger than prednisolone
