|Drug Class: What is Alphagan and why is it prescribed?|
Generic Alphagan helps to reduce pressure in the eye for patients with increased pressure or open-angle glaucoma.
|Drug Mechanism: How does Alphagan work?|
Generic Alphagan acts on receptors (alpha-receptors) in the blood vessels of the eye causing them to constrict. These blood vessels control the production of the watery fluid that fills the rear of the eye. When the blood vessels constrict there is a decrease in the production of this watery fluid.
Generic Alphagan is used in the treatment of glaucoma. This is a condition where the fluid drainage from the eye is impaired, resulting in fluid build-up and increased pressure in the eye.
Generic Alphagan is used as an eye drop so that it can act directly where it is needed. Generic Alphagan may be used in conjunction with beta-blocker eye drops (e.g.betaxolol).
Generic Alphagan may also be used to treat glaucoma that does not respond to beta-blocker eye drops.
|Dosage: How should you take Alphagan|
The usual dose of Generic Alphagan is 1 drop in the affected eye(s) 3 times daily, approximately 8 hours apart.
