Drug Mode of Action ::  

Metoprolol selectively inhibits ?1-adrenergic receptors but has little or no effect on ?2-receptors except in high doses. It does not exhibit membrane stabilising or intrinsic sympathomimetic activity.

Drug Interactions ::

Additive effect w/ catecholamine-depleting drugs (e.g. reserpine) and MAOIs. May antagonise ?1-adrenergic stimulating effects of sympathomimetics. Additive negative effects on SA or AV nodal conduction w/ cardiac glycosides, nondihydropyridine Ca channel blockers. Paradoxical response to epinephrine may occur. Increased plasma concentrations w/ CYP2D6 inhibitors (e.g. bupropion, cimetidine). Increased risk of hypotension and heart failure w/ myocardial depressant general anaesth (e.g. diethyl ether). Risk of pulmonary HTN w/ vasodilators (e.g. hydralazine) in uraemic patients. Reduced plasma levels w/ rifampicin. May increase negative inotropic and negative dromotropic effect of antiarrhythmic drugs (e.g. quinidine, amiodarone). May reduce antihypertensive efficacy w/ indometacin. May increase effects of hypoglycaemics.
