Simbrinza contains which two agents?

Explanation:
Simbrinza contains two agents: brinzolamide and brimonidine. It’s a fixed‑combination eye drop that pairs a carbonic anhydrase inhibitor with an alpha‑2 adrenergic agonist to lower intraocular pressure. Brinzolamide reduces aqueous humor production by inhibiting carbonic anhydrase in the ciliary body, while brimonidine further decreases production (and may help with outflow) by stimulating alpha‑2 receptors. The result is an additive drop in IOP from two different mechanisms. Other listed combinations pair drugs not in this product—for example, a beta-blocker with a carbonic anhydrase inhibitor, or an alpha‑2 agonist with a prostaglandin analog—so they are not Simbrinza.
