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.

Interaction

Brimonidine Tartrate: Possibility of an additive or potentiating effect with CNS depressants e.g. alcohol, barbiturates, opiates, sedatives or anaesthetics. Caution when used with ?-blockers (ophthalmic and systemic), antihypertensives or cardiac glycosides. TCAs can affect the metabolism and uptake of circulating amines. Timolol: Concomitant admin w/ reserpine may increase hypotension and bradycardia. Additive effects w/ other antihypertensives (e.g. hydralazine, methyldopa). Increased ?-adrenergic blockade (e.g. decreased heart rate) w/ quinidine. Rebound HTN due to abrupt withdrawal of clonidine. Hypotensive effect may be antagonised by NSAIDs (e.g. indomethacin, ibuprofen).
