Mode of Action

Brimonidine is an alpha 2-adrenoceptor agonist which works to reduce aqueous humor production and increase uveoscleral flow. Timolol is a non-selective beta-adrenergic receptor blocker. It does not have significant intrinsic sympathomimetic activity, direct myocardial depressant activity or local anaesth activity. Exact mechanism of ocular hypotensive effect is unclear, but it is thought to be related to reduction of aqueous humour formation. beta-blockade also causes lowering of BP.
