Intravenous Emergency treatment of cardiac arrhythmias Adult: Initially, up to 5 mg at a rate of 1-2 mg/min, may repeat at 5-min intervals if needed up to a total dose of 10-15 mg. Prophylaxis or control of arrhythmias on induction of anaesthesia Adult: 2-4 mg as slow inj, may repeat injections of 2 mg as necessary up to max 10 mg. Adjunct in the early management of acute myocardial infarction Adult: Admin w/in 12 hr of the onset of chest pain, 5 mg at 2-min intervals to a total of 15 mg, if tolerated. Patients who have received full IV dose: After 15 min, initiate oral therapy of 50 mg 6 hrly for 2 days. Patients who did not tolerate the full IV dose: Reduced oral dose should be given as and when their condition permits. Subsequent maintenance: 100 mg bid (oral). Patients not given an IV inj: 200 mg in 2 or 4 divided doses started when patient's condition stabilises. Hepatic impairment: Reduce dose. Dosing Considerations In switching from immediate-release to extended-release, same total daily dose of metoprolol should be used In switching between oral and IV dosage forms, equivalent beta-blocking effect is achieved in 2.5:1 (oral-to-IV) ratio

May be taken with or without food.

Contra Indications

2nd or 3rd degree AV block, sick sinus syndrome, hypotension, decompensated heart failure, sinus bradycardia, severe peripheral arterial circulatory disorders, cardiogenic shock, severe asthma and bronchospasm, untreated phaeochromocytoma, Prinzmetal's angina, metabolic acidosis.

Precautions

Patients w/ myasthenia gravis, well-compensated heart failure, bronchospastic disease, AV conduction disorders, substantial cardiomegaly. May mask signs and symptoms of hyperthyroidism and hypoglycaemia. Patients w/ history of cardiac failure or those w/ minimal cardiac reserve. Patients undergoing major surgery involving general anaesth. Avoid abrupt withdrawal as it may precipitate thyroid storm or MI, and may exacerbate angina and ventricular arrhythmias. Hepatic impairment. Pregnancy and lactation. Patient Counselling May affect ability to drive or operate machinery. Monitoring Parameters Monitor BP, ECG and heart rate. Lactation: Drug is concentrated in breast milk; use with caution (American Academy of Pediatrics states that drug is compatible with nursing)

Pregnancy-Lactation

Pregnancy There are no adequate and well-controlled studies in pregnant women Limited data on the use of metoprolol in pregnant women Risk to fetus/mother is unknown; because animal reproduction studies are not always predictive of human response, use if clearly needed Animal data Lopressor has been shown to increase postimplantation loss and decrease neonatal survival in rats at doses up to 11 times the maximum daily human dose of 450 mg, when based on surface area Distribution studies in mice confirm exposure of the fetus when Lopressor is administered to the pregnant animal These limited animal studies do not indicate direct or indirect harmful effects with respect to teratogenicity Fertility Drug effects on the fertility of human have not been studied Lopressor showed effects on spermatogenesis in male rats at a therapeutic dose level, but had no effect on rates of conception at higher doses in animal fertility studies Lactation Lopressor is excreted in breast milk in a very small quantity An infant consuming 1 liter of breast milk daily would receive a dose of less than 1 mg of the 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.

Mode of Action

Metoprolol selectively inhibits beta1-adrenergic receptors but has little or no effect on beta2-receptors except in high doses. It does not exhibit membrane stabilising or intrinsic sympathomimetic activity.
