Mechanism Of Action In the eye, alpha-1 adrenoceptors play a role in vasoconstriction, mydriasis, eyelid retraction, and elevation of intraocular pressure (IOP) whereas alpha-2 adrenoceptors are responsible for IOP reduction via a complex Gi-coupled signaling cascade pathway. Activation of alpha-2 receptors leads to inhibition of adenylyl cyclase and reduction of cyclic AMP levels. As a result, there is a decrease in norpinephrine (NE) release at the synaptic junction, NE-induced stimulation of beta-2 adrenoceptors, and production of aqueous humor by the ciliary epithelium.
Description of the Drug: Brimonidine is an alpha-2 adrenergic agonist used to treat glaucoma and ocular hypertension, as well as facial erythema in rosacea.
