1. What is Alphagan and what is it used for

Alphagan is used to lower high pressure in the eye. The active substance in Alphagan, brimonidine tartrate, belongs to a group of medicines called alpha-2 adrenergic agonists and works by reducing the amount of fluid produced in the eye.

It can be used on its own, when beta-blocker eye drops are not suitable, or with other eye drops, when Alphagan alone is not enough to lower the pressure in the eye in the treatment of open-angle glaucoma or ocular hypertension.
