Abstract
Fatty acid salts of betaxolol, a cardioselective beta-blocker, and ophthalmic compositions containing these salts are described. These new salts have an aqueous solubility significantly less than that of betaxolol hydrochloride. This relatively poor aqueous solubility enables the salts to be slowly released from a suitable ophthalmic vehicle when placed in the aqueous environment of the eye. The salts also exhibit a significantly lower incidence of ocular irritation, as compared to ophthalmic solutions containing betaxolol hydrochloride.
