DRUG INDEX
GENERIC NAME: brimonidine BRAND NAME: Alphagan
DRUG CLASS AND MECHANISM: Brimonidine is used for the treatment of one type of glaucoma , open-angle glaucoma. In this type of glaucoma, too much fluid (aqueous humor) is made within the eye and causes high pressures within the eye. The pressure damages the nerves in the eye responsible for vision, and this ultimately causes blindness. Brimonidine reduces the body's production of aqueous humor and increases the flow of aqueous humor out of the eye, resulting in a decrease in pressure. (It accomplishes this by stimulating alpha type 2 receptors in the eye.) It is the first drug of its class to be used for glaucoma. Brimonidine was approved by the FDA in 1996.
