|Abstract:||Process and composition for reducing intraocular pressure and reducing aqueous humor formation by applying topically to the cornea an effective amount of an aqueous solution of a caronic anhydrase inhibitor comprising a sulfonamide having the following properties: a. sufficiently soluble in water to form at least a 3 mM solution at pH 8.2 or a pKa of not greater than 7.3; b. ether partition coefficient of at least 1.0; c. chloroform partition coefficient of at least 0.01; d. dissociation constant against carbonic anhydrase of not more than 3.times.10.sup.-8 molar; e. first order rate constant for penetration of the sulfonamide through a living rabbit cornea of at least 0.005 hr.sup.-1 ; f. not injurious to the cornea; and g. stable in aqueous solution and in contact with the cornea.|
