What is the therapeutic action of brimonidine?

Brimonidine lowers intraocular pressure by reducing the formation of aqueous humor and, over time, also enhances uveoscleral outflow via acting on the iris-ciliary body 2-adrenergic receptors.

Is brimonidine a vasodilator?

Through the release of endothelium-derived relaxing factor via the 2-adrenergic receptors on endothelial cells, brimonidine tartrate may also cause vasodilation. The positive impact of 0.2% brimonidine tartrate on intraocular pressure was verified by our findings.

What class of drug is brimonidine?

Alpha-adrenergic agonists are a group of medications that includes brimonidine. Brimonidine reduces the quantity of fluid in the eyes in order to work.
