MedKoo CAT#: 317332

CAS#: 70359-46-5 (tartrate)

Description: Brimonidine tartrate is a selective AR, α 2 receptor, agonist used to treat glaucoma. Upon ocular administration, brimonidine tartrate acts on the blood vessels causing them to constrict which leads to a decrease in the production of aqueous humor. Brimonidine tartrate enhances the outflow of aqueous humor. This drug is used to reduce intraocular pressure.
