Xolamid B Ophthalmic Suspension

In patients treated with this drop 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 this.

It is contraindicated in patients who are hypersensitivity to Brinzolamide, Brimonidine Tartrate, or to any ingredient in the formulation and Neonates and Infants (under the age of 2 years).

The most frequently reported adverse reactions in patients treated with Benozol BR occurring in approximately 3 to 5% of patients were blurred vision, eye irritation, dysgeusia (bad taste), dry mouth, and eye allergy. Other adverse reactions that have been reported with the individual components during clinical trials are listed below.

Brinzolamide 1%: The most frequently reported adverse reactions reported with Brinzolamide in 5 to 10% of patients were blurred vision and bitter, sour or unusual taste. Adverse reactions occurring in 1 to 5% of patients were blepharitis, dermatitis, dry eye, foreign body sensation, headache, hyperemia, ocular discharge, ocular discomfort, ocular keratitis, ocular pain, ocular pruritus and rhinitis.

Brimonidine Tartrate 0.2%: Adverse reactions occurring with Brimonidine Tartrate in approximately 10 to
30% of the subjects, in descending order of incidence, included oral dryness, ocular hyperemia, burning and stinging, headache, blurring, foreign body sensation, fatigue/drowsiness, conjunctival follicles, ocular allergic reactions, and ocular pruritus.

Pregnancy Category C. Benozol BR should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus. It is not known whether Benozol BR are excreted in human milk following topical ocular administration. Because many drugs are excreted in human milk and because of the potential for serious adverse reactions in nursing infants from Benozol BR, a decision should be made whether to discontinue nursing or to discontinue the drug, taking into account the importance of the drug to the mother.

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 thromboangitis 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.

Use in Pediatrics: The individual component, Brinzolamide, has been studied in pediatric glaucoma patients 4 weeks to 5 years of age. The individual component, Brimonidine Tartrate, has been studied in pediatric patients 2 to 7 years old. Somnolence (50-83%) and decreased alertness was seen in patients 2 to 6 years old. Benozol BR is contraindicated in children under the age of 2 years

Use in Geriatrics: No overall differences in safety or effectiveness have been observed between elderly and adult patients.

Although no human data are available, electrolyte imbalance, development of an acidotic state, and possible nervous system effects may occur following an oral overdose of Brinzolamide. Serum electrolyte levels (particularly potassium) and blood pH levels should be monitored. Very limited information exists on accidental ingestion of Brimonidine Tartrate in adults; the only adverse event reported to date has been hypotension. Symptoms of Brimonidine Tartrate overdose have been reported in neonates, infants, and children receiving Brimonidine Tartrate as part of medical treatment of congenital glaucoma or by accidental oral ingestion. Treatment of an oral overdose includes supportive and symptomatic therapy; a patent airway should be maintained.
