A brief description of Cosopt eye drops:
Cosopt possesses the combination of two active drugs known as Dorzolamide and Timolol that is used to decrease the pressure inside the eye due to glaucoma. It is also used to prevent blindness by lowering high pressure inside the eye. Timolol comes under the class of drugs called beta-blockers and Dorzolamide comes under the class of drugs called carbonic anhydrase inhibitors.
Mechanism of action of Cosopt eye drops:
Dorzolamide and Timolol both decreases the elevated intraocular pressure, which is either or not associated with glaucoma. Dorzolamide inhibits the carbonic anhydrase in the ciliary muscle in the eye and thereby decreases aqueous humor Timolol is a beta-adrenergic receptor inhibitor that decreases the amount of fluid formation in the eye.
