Brimonidine ophthalmic drops are a type of medication used to treat high pressure inside the eye, including glaucoma, and to reduce redness and swelling in the eyes. They belong to a class of medications known as alpha-2 adrenergic agonists, which work by decreasing the amount of fluid produced in the eye and increasing the outflow of fluid from the eye, thereby lowering the pressure inside the eye.
The active ingredient, brimonidine, is a selective alpha-2 adrenergic receptor agonist, which means it targets specific receptors in the eye to produce its therapeutic effects. By stimulating these receptors, brimonidine reduces the production of aqueous humor, the clear fluid that fills the front part of the eye, and increases the outflow of this fluid through the trabecular meshwork, a spongy tissue located near the base of the iris.
