Cosopt

Contain 2 active ingredients: Dorzolamide HCl 20 mg & Timolol Maleate 5 mg. These are both medicines that decrease raised pressure within the eye.

The pressure within the eyeball is normally maintained by a continuous flow of liquid called aqueous humour through the eyeball. Aqueous humour is produced by a part of the eye called the ciliary body. If aqueous humour builds up inside the eyeball, this increases the pressure within the eyeball. This pressure needs to be reduced, as otherwise it can damage the optic nerve and impair vision.

Timolol and dorzolamide work in different ways to reduce the production of aqueous humour and so decrease its build-up inside the eyeball. They both therefore decrease the pressure in the eyeball.

Timolol is a type of medicine called a beta-blocker. These medicines block beta receptors in various parts of the body. Blocking the beta receptors in the eye reduces the amount of aqueous humour that is produced.

Dorzolamide is a type of medicine called a carbonic anhydrase inhibitor. It works by blocking the action of an enzyme in the body called carbonic anhydrase. Carbonic anhydrase is usually responsible for the production of a salt called bicarbonate in the body. Bicarbonate is needed for the production of the aqueous humour. By decreasing the production of bicarbonate, dorzolamide also decreases the production of aqueous humour.

Cosopt eye drops are used to treat glaucoma when treatment with a beta-blocker eye drop on its own has not lowered the pressure in the eye sufficiently.

What is it used for?

Open angle glaucoma.

Pseudo-exfoliative glaucoma
