Mechanism of action

Brimonidine selectively binds to alpha-2 adrenergic receptors on the ciliary body and trabecular meshwork of the eye. This activation reduces the production of aqueous humor (the fluid inside the eye) and enhances its drainage through the uveoscleral pathway, thereby lowering intraocular pressure. The drug has minimal systemic absorption when applied topically to the eye.
