Dorzolamide (trade name Trusopt) is a carbonic anhydrase inhibitor. It is an anti-glaucoma agent and topically applied in the form of eye drops. This drug, developed by Merck, was the first drug in human therapy (market introduction 1995) which resulted from structure-based drug design. Dorzolamide hydrochloride is used to lower increased intraocular pressure in open-angle glaucoma and ocular hypertension. The combination of dorzolamide with timolol is marketed under the trade name Cosopt.
Dorzolamide HCl is a water-soluble, potent inhibitor of human carbonic anhydrase II and IV with Ki of 1.9 nM and 31 nM, respectively, used as anti-glaucoma agent.
