Carbonic anhydrase inhibitors are used to treat glaucoma, altitude sickness, and certain types of seizures. They also have other uses, such as managing fluid buildup in the body. These medications work by reducing the production of fluid in the eye to lower eye pressure, or by changing the balance of electrolytes in the body. You can find these medications in both oral and eye drop forms. Examples include dorzolamide (Trusopt), brinzolamide (Azopt), acetazolamide, methazolamide, and dichlorphenamide (Keveyis). Your prescriber can help you choose the form that best fits your needs.
