Brimonidine Tartrate
Pharmacology
Brimonidine is an α-2 adrenoreceptor agonist that is more selective for the α-2 adrenoreceptor than α-1. Topical administration of Brimonidine Tartrate eye drops decreases intraocular pressure (IOP) in humans. When used as directed Brimonidine Tartrate have the action of reducing elevated IOP with minimal effect on cardiovascular parametres. Brimonidine Tartrate eye drops have a rapid onset of action with the peak ocular hypotensive effect occurring at two hours post-dosing. The duration of effect is 12 hours or greater. Fluorophotometric studies in animals and humans suggest that Brimonidine Tartrate has a dual mechanism of action. Brimonidine Tartrate eye drops lower IOP by reducing aqueous humor production and enhancing uveoscleral outflow.
Dosage Administration

This ophthalmic solution may be used concomitantly with other topical ophthalmic drug products to lower intraocular pressure. If more than one topical ophthalmic product is being used, the products should be administered at least 5 minutes apart. 0.15% ophthalmic solution: The recommended dose is one drop of 0.15% ophthalmic solution in the affected eye(s) three times daily, approximately 8 hours apart. 0.025% ophthalmic solution: Instill 1 drop in the affected eye(s) every 6-8 hours.
