Curator's Comment:: description was created based on several sources, including: https://www.drugs.com/mtm/brimonidine-ophthalmic.html http://www.drugbank.ca/drugs/DB00484 DOI: 10.1002/9781118541203.xen125

Brimonidine reduces the amount of fluid in the eye, which decreases pressure inside the eye. Brimonidine ophthalmic (for the eyes) is used to treat open-angle glaucoma or ocular hypertension (high pressure inside the eye). Brimonidine is an alpha adrenergic receptor agonist (primarily alpha-2). Fluorophotometric studies in animals and humans suggest that Brimonidine has a dual mechanism of action by reducing aqueous humor production and increasing uveoscleral outflow. Adverse reactions occurring in approximately 1020% of the subjects receiving brimonidine ophthalmic solution (0.1-0.2%) included: allergic conjunctivitis, conjunctival hyperemia, and eye pruritus. Because Brimonidine may reduce blood pressure, caution in using drugs such as antihypertensives and/or cardiac glycosides with Brimonidine is advised.

Sample Use Guides

In Vivo Use Guide

One drop in the affected eye(s), three times daily, approximately 8 hours apart

Route of Administration: Topical

In Vitro Use Guide

Cells were pretreated for 6 h with different doses of Brimonidine tartrate 0.1% (1/2×, 1×, 5×, 10×), followed by a 24-h exposure to 100 μM of Hydroquinone. The ROS levels decreased at 1×, 5×, and 10× doses of Brimonidine in ARPE-19 but only at 10× on MIO-M1 cells.
