brinzolamide and its Impurities
Brinzolamide is a highly specific, non-competitive, reversible carbonic anhydrase inhibitor. It is used to treat high pressure inside the eye due to glaucoma or other eye diseases. Lowering high pressure inside the eye helps to prevent blindness.. Reference standards of Brinzolamide API, and its pharmacopeial, non pharmacopeial impurities, and stable isotopes are listed below
