Brimonidine (bri-MOE-ni-deen ) is a drug used to treat glaucoma. It acts via decreasing aqueous humor synthesis.

Brimonidine is an alpha2 receptor agonist.

Alpha 2 agonists, through the activation of the Gi GPCR, inhibit the production of AC. This reduces cAMP and hence Aqueous Humour production by the ciliary body.
