Brimonidine and para-aminoclonidine (PAC) are imidazoline compounds and relatively selective alpha 2-adrenoreceptor agonists.They are used for the treatment of glaucoma and ocular hypertension.1–5 Brimonidine and PAC appear to have similar mechanisms of action in their effect on intraocular pressure. Common Questions and Answers about Brimonidine mechanism of action. While brimonidine reduces IOP initially by reducing aqueous humor production, over time this effect fades and uveoscleral outflow of aqueous humor from the eye increases. Brimonidine is an alpha adrenergic receptor agonist (primarily alpha-2). Fluorophotometric studies in animals and humans suggest that Brimonidine Tartrate has a dual mechanism of action by reducing aqueous humor production and increasing uveoscleral outflow. 12.1 Mechanism of Action.

I am not physically restricted - I walk 1 mile or more day and do 10 minutes of other light exercises most days. The doctor prescribed brimonidine tatar .2% to reduce the size of the pupil. MECHANISM OF ACTION. Terms in this set (6) generic name. It is administered as a topical eye drop three times-daily. Brimonidine is an α 2 adrenergic agonist.. α 2 agonists, through the activation of a G protein-coupled receptor, inhibit the activity of adenylate cyclase.This reduces cAMP and hence aqueous humour production by the ciliary body.. Learn vocabulary, terms, and more with flashcards, games, and other study tools. Brimonidine tartrate ophthalmic solution, 0.2% is a relatively selective alpha-2 adrenergic receptor agonist with a peak ocular hypotensive effect occurring at two hours post-dosing. Persistent centrofacial erythema is a predominant component of rosacea. Elevated Intraocular Pressure Therapy . Applied once daily, brimonidine works quickly to reduce the redness of rosacea and the beneficial effects last up to 12 hours. Apraclonidine (), also known under the brand name Iopidine, is a sympathomimetic used in glaucoma therapy. combigan. It appears to act by decreasing aqueous humor production and increasing aqueous outflow {01}. Action And Clinical Pharmacology: Mechanism of Action: Brimonidine is a relatively selective alpha adrenergic receptor agonist that in radioligand binding assays and in functional assays, is approximately 1 000 times more selective for the alpha-2 adrenoceptor than the alpha-1 adrenoceptor. 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.
