Each ml contains: Active substance: Brinzolamide USP 10 mg and Brimonidine Tartrate BP 2 mg.
Preservative: Benzalkonium Chloride 0.03 mg.
Benozol BR is a sterile ophthalmic suspension containing Brinzolamide + Brimonidine for topical administration to the eye.
Clinical Pharmacology:
Benozol BR is comprised of two components: Brinzolamide (carbonic anhydrase inhibitor) and Brimonidine Tartrate (alpha 2 adrenergic receptor agonist). Each of these two components decreases elevated intraocular pressure. Elevated intraocular pressure is a major risk factor in the pathogenesis of optic nerve damage and glaucomatous visual field loss.
Brinzolamide inhibits carbonic anhydrase in the ciliary processes of the eye to decrease aqueous humor secretion, presumably by slowing the formation of bicarbonate ions with subsequent reduction in sodium and fluid transport. Brinzolamide has a peak ocular hypotensive effect occurring at 2 to 3 hours post-dosing.
Fluorophotometric studies in animals and humans suggest that Brimonidine Tartrate has a dual mechanism of action by reducing aqueous humor production and increasing uveoscleral outflow. Brimonidine Tartrate has a peak ocular hypotensive effect occurring at two hours post-dosing. The result is a reduction in intraocular pressure (IOP).
Benozol BR is a fixed combination of a carbonic anhydrase inhibitor and an alpha 2 adrenergic receptor agonist indicated for the reduction of elevated intraocular pressure in patients with open-angle glaucoma or ocular hypertension.
Shake well before use.
Instill one drop in the affected eye(s) three times daily. If more than one topical ophthalmic drug is being used, the drugs should be administered at least five (5) minutes apart.
*Prescription only*
In patients treated with Benozol BR rare instances to drug interactions have occurred with high-dose salicylate therapy, CNS Depressants, Antihypertensives/ Cardiac Glycosides, Tricyclic Antidepressants, Monoamine Oxidase Inhibitors. Therefore, the potential for such drug interactions should be considered in patients receiving Benozol BR.
Benozol BR contains Brinzolamide, a sulfonamide, and although administered topically is absorbed systemically. Therefore, the same types of adverse reactions that are attributable to sulfonamides may occur with topical administration of Benozol BR. Fatalities have occurred due to severe reactions to sulfonamides including Stevens-Johnson syndrome, toxic epidermal necrolysis, fulminant hepatic necrosis, agranulocytosis, aplastic anemia, and other blood dyscrasias.
Brimonidine Tartrate also may potentiate syndromes associated with vascular insufficiency. Benozol BR should be used with caution in patients with depression, cerebral or coronary insufficiency, Raynaud’s phenomenon, orthostatic hypotension, or thromboangiitis obliterans. anemia, and other blood dyscrasias. Brinzolamide and its metabolite are excreted predominantly by the kidney, Benozol BR is not recommended in renal impairment patients. The preservative in Benozol BR, benzalkonium chloride, may be absorbed by soft contact lenses. Contact lenses should be removed during instillation of Benozol BR but may be reinserted 15 minutes after.
Store at below 30°C in a dry place protected from light and freezing. Do not touch dropper tip to any surface. Do not use after one month of first opening of the bottle.
