This medicine contains 20 mg/mL the active ingredient dorzolamide which belongs to group of medicines called carbonic anhydrase inhibitors. These medicines block the action of carbonic anhydrase enzyme which is responsible for the production of aqueous humour (fluid in the front part of the eye) that causes high pressure within your eye. Dorzolamide is prescribed for the treatment of glaucoma (damage of the optic nerve at the back of the eye caused by high pressure in the eye) and ocular hypertension.
