A 2017
In 2013, the FDA approved topical application of brimonidine 0.33% gel for persistent facial redness of rosacea.
Mechanism of action
Brimonidine is an α2 adrenergic agonist.[1]
α2 agonists, through the activation of a
Peripheral α2 agonist activity results in vasoconstriction of blood vessels (as opposed to central α2 agonist activity that decreases sympathetic tone, as can be seen by the medication clonidine). This vasoconstriction may explain the acute reduction in aqueous humor flow. The increased uveoscleral outflow from prolonged use may be explained by increased prostaglandin release due to α adrenergic stimulation. This may lead to relaxed ciliary muscle and increased uveoscleral outflow.[9]
