Indications
Alphagan (brimonidine) eye drops are used to treat open-angle glaucoma, ocular hypertension, and to reduce pressure inside the eyes. It works by lowering high fluid pressure in the eye, which reduces the risk of vision loss.
Brimonidine belongs to the family of medications known as alpha-2-adrenergic receptor agonists. It is available in eye-drop form and is used to reduce the pressure inside the eye for people with open-angle glaucoma or intraocular hypertension (increased pressure in the eye).
