Why Cosopt Eyedrops are prescribed?
The combination of dorzolamide and timolol is used to treat eye conditions, including glaucoma and ocular hypertension, in which increased pressure can lead to a gradual loss of vision. Dorzolamide and timolol are used for patients whose eye condition has not responded to another medication. Dorzolamide is in a class of medications called topical carbonic anhydrase inhibitors. Timolol is in a class of medications called topical beta-blockers. Dorzolamide and timolol lower pressure in the eye by decreasing the production of natural fluids in the eye.
