brimonidine tartrate 2 MG/ML / timolol 5 MG/ML Ophthalmic Solution
What it is used for
Brimonidine Tartrate/Timolol Maleate Ophthalmic Solution, 0.2%/0.5% is indicated for the reduction of elevated intraocular pressure (IOP) in patients with glaucoma or ocular hypertension who require adjunctive or replacement therapy due to inadequately controlled IOP. The IOP-lowering of brimonidine tartrate/timolol maleate ophthalmic solution dosed twice a day was slightly less than that seen with the concomitant administration of 0.5% timolol maleate ophthalmic solution dosed twice a day and 0.2% brimonidine tartrate ophthalmic solution dosed three times per day. Brimonidine Tartrate/Timolol Maleate Ophthalmic Solution is a combination of brimonidine tartrate, an alpha-adrenergic receptor agonist, and timolol maleate, a beta-adrenergic receptor inhibitor indicated for the reduction of elevated intraocular pressure (IOP) in patients with glaucoma or ocular hypertension who require adjunctive or replacement therapy due to inadequately controlled IOP. The IOP-lowering of brimonidine tartrate/timolol maleate ophthalmic solution dosed twice a day was slightly less than that seen with the concomitant administration of timolol maleate ophthalmic solution, 0.5% dosed twice a day and brimonidine tartrate ophthalmic solution, 0.2% dosed three times per day.

Description
Brimonidine tartrate/Timolol maleate ophthalmic solution 0.2%/0.5%, sterile, contains brimonidine tartrate, a relatively selective alpha -2 adrenergic receptor agonist, and timolol maleate, a non-selective beta-adrenergic receptor inhibitor (topical intraocular pressure lowering agent) for topical ophthalmic use.
The structural formulae are: Brimonidine tartrate: 5-bromo-6-(2-imidazolidinylideneamino) quinoxaline L-tartrate; MW= 442.24 Timolol maleate: (-)-1-(tert-butylamino)-3-[(4-morpholino-1,2,5-thiadiazol-3-yl)-oxy]-2-propanol maleate (1:1) (salt); MW=432.50 as the maleate salt In solution, brimonidine tartrate/timolol maleate ophthalmic solution 0.2%/0.5% has a clear, greenish-yellow color. It has an osmolality of 260 to 330 mOsmol/kg and a pH during its shelf life of 6.5 to 7.3. Brimonidine tartrate appears as pale yellow colored powder to wheatish colored powder and is soluble in water, practically insoluble in anhydrous ethanol and in toluene. Timolol maleate appears as a white or almost white, crystalline powder or colorless crystals and is soluble in water, ethanol (96%) and in methanol, sparingly soluble in chloroform and in propylene glycol, insoluble in ether and in cyclohexane. Each mL of brimonidine tartrate/timolol maleate ophthalmic solution contains the active ingredients brimonidine tartrate 0.2% and timolol 0.5% with the inactive ingredients benzalkonium chloride 0.005%, disodium hydrogen phosphate heptahydrate, monobasic sodium phosphate monohydrate, hydrochloric acid and/or sodium hydroxide to adjust pH (6.5 to 7.3), water for injection.
