Uses
1 INDICATIONS AND USAGE SIMBRINZA (brinzolamide/brimonidine tartrate ophthalmic suspension) 1%/0.2% is a fixed combination of a carbonic anhydrase inhibitor and an alpha 2 adrenergic receptor agonist indicated for the reduction of elevated intraocular pressure (IOP) in patients with open-angle glaucoma or ocular hypertension. SIMBRINZA is a combination of brinzolamide, a carbonic anhydrase inhibitor, and brimonidine tartrate, an alpha adrenergic agonist, indicated for the reduction of elevated intraocular pressure (IOP) in patients with open-angle glaucoma or ocular hypertension. (1)
Dosage
2 DOSAGE AND ADMINISTRATION The recommended dose is one drop of SIMBRINZA in the affected eye(s) three times daily. Shake well before use. SIMBRINZA ophthalmic suspension may be used concomitantly with other topical ophthalmic drug products to lower IOP. If more than one topical ophthalmic drug is being used, the drugs should be administered at least five (5) minutes apart. 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 minutes apart. (2)
Side Effects
6 ADVERSE REACTIONS Most common adverse reactions occurring in approximately 3% to 5% of patients included blurred vision, eye irritation, dysgeusia (bad taste), dry mouth, eye allergy. (6.1) To report SUSPECTED ADVERSE REACTIONS, contact Alcon Laboratories, Inc. at 1-800-757-9195 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch. 6.1 Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to the rates in the clinical trials of another drug and may not reflect the rates observed in practice. SIMBRINZA In two clinical trials of three months duration 435 patients were treated with SIMBRINZA, and 915 were treated with the two individual components.
Interactions
7 DRUG INTERACTIONS Oral Carbonic Anhydrase Inhibitors (7.1) High-dose Salicylate Therapy (7.2) Central Nervous System Depressants (7.3) Antihypertensives/Cardiac Glycosides (7.4) Tricyclic Antidepressants (7.5) Monoamine Oxidase (MAO) Inhibitors (7.6) 7.1 Oral Carbonic Anhydrase Inhibitors There is a potential for an additive effect on the known systemic effects of carbonic anhydrase inhibition in patients receiving an oral carbonic anhydrase inhibitor and brinzolamide ophthalmic suspension 1%, a component of SIMBRINZA ophthalmic suspension. The concomitant administration of SIMBRINZA and oral carbonic anhydrase inhibitors is not recommended. 7.2 High-Dose Salicylate Therapy Carbonic anhydrase inhibitors may produce acid-base and electrolyte alterations.
Warnings
5 WARNINGS AND PRECAUTIONS Potential for sulfonamide hypersensitivity reactions because of the brinzolamide component (5.1) Potential for corneal endothelium cell loss (5.2) Severe renal impairment may limit the metabolism of the brinzolamide component (5.3) 5.1 Sulfonamide Hypersensitivity Reactions SIMBRINZA 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 SIMBRINZA. 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. 4 CONTRAINDICATIONS Hypersensitivity to any component of this product. (4.1) Neonates and infants (under the age of two years). (4.2) 4.1 Hypersensitivity SIMBRINZA is contraindicated in patients who are hypersensitive to any component of this product.
Pregnancy
8.1 Pregnancy Developmental toxicity studies with brinzolamide in rabbits at oral doses of 1, 3, and 6 mg/kg/day (20, 60, and 120 times the recommended human ophthalmic dose) produced maternal toxicity at 6 mg/kg/day and a significant increase in the number of fetal variations, such as accessory skull bones, which was only slightly higher than the historic value at 1 and 6 mg/kg.
