Abstract
Analogs are prepared of the carbonic anhydrase inhibitors methazolamide, and dichlorphenamide. The analogs link a cleavable functional group to the pharmacologically active carbonic anhydrase inhibitor resulting in compounds of improved corneal permeability, which are non-irritable to the eye and which are effective topically to inhibit intraocular pressure.
