About Cosopt
Cosopt is indicated for the treatment of elevated intraocular pressure (IOP) in patients with open-angle glaucoma, or pseudoexfoliative glaucoma when monotherapy with a beta-blocker is not enough. Timolol belongs to a group of medicines called beta-blockers. These drugs lower intraocular pressure in different ways. Cosopt is prescribed to reduce elevated eye pressure in the treatment of glaucoma when the use of beta-blocker eye drops as monotherapy is not appropriate.
Cosopt is indicated for the treatment of elevated intraocular pressure (IOP) in patients with open-angle glaucoma, or pseudoexfoliative glaucoma when monotherapy with a beta-blocker is not enough.
Cosopt eye drops solution is comprised of two main active ingredients, Dorzolamide and Timolol, each of these two components lower elevated intraocular pressure, reducing the secretion of aqueous humor, although each using different mechanisms of action. Dorzolamide hydrochloride is a potent inhibitor of human carbonic anhydrase II. Inhibition of carbonic anhydrase in the ciliary processes of the eyes decreases the secretion of aqueous humor, probably slowing down the formation of bicarbonate ions with the subsequent reduction of sodium and fluid transport. Timolol maleate is a non-selective blocking agent for beta-adrenergic receptors. For now, the exact mechanism of action is not clearly established.
The main benefit this eye drop solution is associated with is being used to reduce high intraocular pressure (ocular hypertension) and in the treatment of glaucoma (open-angle glaucoma, pseudoexfoliative glaucoma). This is thanks to the combination of the main active ingredients: Dorzolamide and timolol.
