What is brimonidine?
Brimonidine is a prescription medicine that is used to treat rosacea.
Brimonidine tartrate ophthalmic solution 0.2%, sterile, is a relatively selective alpha-2 adrenergic receptor agonist (topical intraocular pressure lowering agent).
The structural formula of brimonidine tartrate is:
5-Bromo-6-(2-imidazolidinylideneamino) quinoxaline L-tartrate; MW= 442.24
In solution, brimonidine tartrate ophthalmic solution 0.2% has a clear, greenish-yellow color. It has an osmolality of 280 to 330 mOsml/kg and a pH of 5.6 to 6.6.
Each mL of brimonidine tartrate ophthalmic solution contains the active ingredient brimonidine tartrate 0.2% (2 mg/mL) with the inactive ingredients benzalkonium chloride 0.005% (0.05 mg/mL) as a preservative; citric acid; polyvinyl alcohol; sodium chloride; sodium citrate; and water for injection. Hydrochloric acid and/or sodium hydroxide may be added to adjust pH.
Mechanism of Action
Brimonidine tartrate ophthalmic solution 0.2% is a relatively selective alpha-2 adrenergic receptor agonist with a peak ocular hypotensive effect occurring at two 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.
