Barinep 0.1% Ophthalmic Suspension 5mL is a medication used to treat elevated intraocular pressure in patients with ocular hypertension or open-angle glaucoma. The active ingredient in Barinep is Brimonidine Tartrate 0.1%, which is a selective alpha-2 adrenergic receptor agonist that reduces the production of aqueous humor, thereby lowering intraocular pressure. Barinep is applied as drops to the affected eye(s), as directed by a healthcare professional. It is important to follow the dosing instructions carefully and to avoid touching the tip of the dropper to any surface or the eye to prevent contamination. Common side effects of Barinep include stinging or burning sensation, redness, itching, dry mouth, and blurred vision.
