Brimonidine (bri-MOE-ni-deen, brand names Alphagan and Alphagan-P) is a drug used to treat open-angle glaucoma or ocular hypertension. Alphagan is also used to induce miosis for people suffering from poor night vision after Lasik or PRK surgery.

It acts via decreasing synthesis of aqueous humor, and increasing the amount that drains from the eye. As a treatment for glaucoma, it is usually given in eyedrop form.

Brimonidine is an α2-adrenergic receptor agonist.

Alpha 2 agonists, through the activation of the Gi GPCR, inhibit the activity of adenylate cyclase. This reduces cAMP and hence Aqueous Humour production by the ciliary body.

Clinical uses

Brimonidine is indicated for the lowering of intraocular pressure in patients with open-angle glaucoma or ocular hypertension.
