like propranolol and oxprenolol, timolol binds at beta(1)-adrenergic receptors in the heart and vascular smooth muscle, inhibiting the effects of the catecholamines epinephrine and norepinephrine and decreasing heart rate, cardiac output, and systolic and diastolic blood pressure. it also blocks beta-2 adrenergic receptors located in bronchiole smooth muscle, causing vasoconstriction.
