The doctor prescribed brimonidine tatar .2% to reduce the size of the pupil. Pharmacokinetics Absorption These two components lower intraocular pressure (IOP) in patients with open-angle glaucoma (OAG) and ocular hypertension (OHT) by suppressing the formation of aqueous humour from the ciliary process in the eye. It is an α 2 adrenergic receptor agonist and a weak α 1 adrenergic receptor agonist. In two 1 year studies, brimonidine has been shown to lower intraocular pressure by mean values of approximately 4-6 mmHg. Flourophotometric studies in animals and humans suggest that brimonidine tartrate has a dual mechanism of action. This reduces cAMP and hence aqueous humour production by the ciliary body.
