ABSTRACT:
Although dibasic carbonic anhydrase inhibitors (C.A.I.) can be administered systemically by oral or intravenous routes, attempts to administer them topically were inadvisable because of their elevated pH. The mono-alkali metal salts in the treatment of intraocular hypertension especially the sodium and potassium salts, of dibasic salt-forming C.A.I. are as effective in lowering intraocular pressure as dialkali metal salts of dibasic C.A.I. while having a pH more in harmony with ocular pH. They are found particularly useful when administered in conjunction with an ophthalmologically acceptable water-soluble polymer such as hydroxypropylcellulose in an aqueous carrier.
