Brinzolamide/brimonidine: a review of its use in patients with open-angle glaucoma or ocular hypertension.
Brinzolamide 1 %/brimonidine 0.2 % ophthalmic suspension (Simbrinza(®)) is a fixed-combination of a carbonic anhydrase inhibitor and an α2-adrenergic receptor agonist that is indicated for the reduction of elevated intraocular pressure (IOP) in patients with open-angle glaucoma or ocular hypertension in both the USA and EU (with the EU indication restricted to patients for whom monotherapy provides insufficient IOP reduction). In phase III randomized trials, both three-times-daily and twice-daily administration of brinzolamide/brimonidine provided significantly greater IOP-lowering efficacy over 3-6 months than either of its individual components alone, and twice-daily brinzolamide/brimonidine was noninferior to concomitant administration of brinzolamide plus brimonidine over 6 months in this regard. Brinzolamide/brimonidine was generally well tolerated, with a tolerability profile that was consistent with its individual components and with no unexpected safety findings. Therefore, brinzolamide/brimonidine is an effective treatment option for patients with open-angle glaucoma or ocular hypertension, providing a convenient alternative for those patients who require multiple IOP-lowering medications. Brinzolamide/brimonidine is the first available fixed-combination that does not contain timolol, and maybe particularly suited to patients with comorbidities that restrict treatment with β-adrenergic receptor antagonists.
