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 while simultaneously enhancing its drainage through the uveoscleral pathway, thereby lowering intraocular pressure. The purite formulation is a preserved formulation designed for topical ophthalmic use.
