Name	Dorzolamide
Groups	approved
Description	Dorzolamide is a non-bacteriostatic sulfonamide derivative [A1304] and topical carbonic anhydrase (CA) inhibitor that treats elevated intraocular pressure (IOP) associated with open-angle glaucoma and ocular hypertension.[L11377] It works by blocking an enzyme in the ciliary process that regulates ion balance and fluid pressure in the eyes.[A1303] Unlike oral CA inhibitors, dorzolamide has negligible effects of acid-base or electrolyte disturbances and other systemic adverse effects.[A1304] First marketed in 1995,[A190624] dorzolamide is available in ophthalmic solutions as monotherapy marketed as Trusopt [L11377] or in combination with [timolol] as Cosopt PF.[L11380]

Indication	Dorzolamide is indicated for the management of elevated intraocular pressure in patients with ocular hypertension or open-angle glaucoma.[L11377] It can also be used in combination with [timolol] for the same indication in patients who are insufficiently responsive to ophthalmic beta-blockers.[L11380] Its pre-operative use was also investigated to prevent elevated intraocular pressure after neodynium yttrium aluminum garnet laser posterior capsulotomy.[A190183]
