Notes: Brinzolamide is a potent inhibitor of carbonic anhydrase II (CAII) and CAIV (IC50s = 3.19 and 45.3 nM, respectively).{53202} It is selective for CAII and CAIV over CAI (IC50 = ~1,365 nM). Brinzolamide (30 mg/kg) reduces intestinal charcoal meal progression by 44% and prolongs pentobarbital sodium-induced sleep time by 35% in mice. Topical administration of brinzolamide (0.25, 0.5, and 1 mg/eye) reduces intraocular pressure (IOP) in a rabbit model of spontaneous ocular hypertension. It also reduces IOP in a cynomolgus monkey model of argon laser trabeculoplasty-induced ocular hypertension. Formulations containing brinzolamide have been used in the treatment of glaucoma and ocular hypertension.
