CO-DORZAL Eye Drops (5ml) contain dorzolamide and timolol, used to treat elevated intraocular pressure in conditions like glaucoma. Dorzolamide is a carbonic anhydrase inhibitor that reduces the production of fluid in the eye, while timolol is a beta-blocker that decreases fluid production and pressure. These eye drops help prevent damage to the optic nerve and vision loss. They are typically used as directed by a healthcare provider.
