Brinzolamide is a highly specific carbonic anhydrase (CA) inhibitor which lowers intraocular pressure (IOP) by reducing the rate of aqueous humour formation. Formulated as a 1% ophthalmic suspension (Azopt) and administered twice or three times daily, brinzolamide is indicated for the topical management of primary open-angle glaucoma (POAG) and ocular hypertension (OH) as either monotherapy or adjunctive therapy with topical beta-blockers.

Brinzolamide is a novel carbonic anhydrase inhibitor that elicits an ocular hypotensive effect when instilled topically. A multicenter, double-masked, placebo-controlled, parallel trial was conducted to evaluate the optimal intraocular pressure (IOP)-lowering concentration and ocular tolerability of topically administered brinzolamide (0.3%, 1%, 2%, and 3%) in patients with primary, open-angle glaucoma or ocular hypertension.

To assess the effects of brinzolamide and dorzolamide on ocular haemodynamics and retinal oxygen saturation in patients with primary open-angle glaucoma (OAG). This pilot study suggests that brinzolamide and dorzolamide may increase retinal oxygen saturation in patients with OAG.

Brinzolamide 1.0% produced clinically relevant intraocular pressure reductions in substantial numbers of patients. Brinzolamide's effectiveness equaled that of dorzolamide 2.0% and it produced less ocular discomfort (burning and stinging) on instillation.
