Mechanism of action

Carbonic anhydrase II is an enzyme that catalyzes the production of aqueous humor in the ciliary body of the eye. By inhibiting this enzyme, dorzolamide decreases aqueous humor secretion, which reduces intraocular pressure. This mechanism makes it effective for treating glaucoma and ocular hypertension, conditions where elevated intraocular pressure can damage the optic nerve.
