| This is a combination medication that contains two ingredients: dorzolamide and timolol. Dorzolamide is a member of the family of medications known as carbonic anhydrase inhibitors. Timolol is a member of the family of medications known as beta-blockers. Together, these medications are used to reduce the pressure inside the eye for people with open-angle glaucoma or ocular hypertension (increased pressure in the eye). These medications work by reducing the production of fluid in the eye, thereby lowering the pressure in the eye. |
