What is Cosopt?

Cosopt (generic name: dorzolamide hydrochloride & timolol maleate) is an ophthalmic solution indicated to manage the reduction of elevated pressure in the eye or IOP (intraocular pressure) among patients with open-angle glaucoma and ocular hypertension. By lowering the pressure inside the eye, blindness could be prevented.

This eye solution is a combination of carbonic anhydrase inhibitor and beta-adrenergic receptor blocking agent. This medication reduces aqueous humor secretion to decrease intraocular pressure. Cosopt also inhibits carbonic anhydrase in the ciliary processes of the eye by slowing the formation of bicarbonate ions, succeeding in a reduction in sodium and fluid transport.

This is available in Cosopt 20 mg/mL dorzolamide + 5 mg/mL timolol solution.
