Brinzolamide is a medication that belongs to the class of drugs known as carbonic anhydrase inhibitors. It is primarily used in the treatment of glaucoma, a condition characterized by increased pressure within the eye that can lead to optic nerve damage and vision loss.Brinzolamide works by inhibiting the enzyme carbonic anhydrase in the eye, which reduces the production of fluid (aqueous humor) in the eye. By decreasing the production of fluid, brinzolamide helps to lower intraocular pressure, which is important in managing glaucoma and preventing further damage to the optic nerve.
