Brinzolamide¿¡ ´ëÇÑ Mechanism_Of_Action Á¤º¸ Brinxolamide is both a sulfonamide and a carbonic anhydrase II inhibitor. Carbonic anhydrase catalyzes the reversible reaction involving the hydration of carbon dioxide and the dehydration of carbonic acid. Inhibition of carbonic anhydrase in the ciliary processes of the eye decreases aqueous humor secretion, presumably by slowing the formation of bicarbonate ions, with subsequent reduction in sodium and fluid transport. The result is a reduction in intraocular pressure, and thereby a reduction in the risk of optic nerve damage and glaucomatous visual field loss.
Pharmacology
Brinzolamide¿¡ ´ëÇÑ Pharmacology Á¤º¸ Used in the treatment of glaucoma, brinzolamide inhibits aqueous humor formation and reduces elevated intraocular pressure. Elevated intraocular pressure is a major risk factor in the pathogenesis of optic nerve damage and glaucomatous visual field loss.

Brinzolamide¿¡ ´ëÇÑ Description Á¤º¸ Brinzolamide is a carbonic anhydrase inhibitor. Carbonic anhydrase (CA) is an enzyme found in many tissues of the body including the eye. It catalyzes the reversible reaction involving the hydration of carbon dioxide and the dehydration of carbonic acid. In humans, carbonic anhydrase exists as a number of isoenzymes, the most active being carbonic anhydrase II (CA-II). Inhibition of carbonic anhydrase in the ciliary processes of the eye decreases aqueous humor secretion, presumably by slowing the formation of bicarbonate ions with subsequent reduction in sodium and fluid transport. The result is a reduction in intraocular pressure. Brinzolamide is indicated in the treatment of elevated intraocular pressure in patients with ocular hypertension or open-angle glaucoma.
