Metoprolol Tartrate
Contraindications
Bronchospastic Diseases: Because of its relative beta 1 ‐selectivity, however, Metoprolol may be used with caution in patients with bronchospastic disease who do not respond to, or cannot tolerate other antihypertensive treatment. Major Surgery: The necessity or desirability of withdrawing beta‐blocking therapy prior to major surgery is controversial; the impaired ability of the heart to respond to reflex adrenergic stimuli may augment the risks of general anesthesia and surgical procedures. Diabetes and Hypoglycemia: Beta‐blockers may mask tachycardia occurring with hypoglycemia, but other manifestations such as dizziness and sweating may not be significantly affected. Peripheral Vascular Disease: Beta‐blockers can precipitate or aggravate symptoms of arterial insufficiency in patients with peripheral vascular disease. Calcium Channel Blockers: Because of significant inotropic and chronotropic effects in patients, caution should be exercised in patients treated with these agents concomitantly.
Side Effects
Pregnancy Category C. There are no adequate and well‐controlled studies in pregnant women. This drug should be used during pregnancy only if clearly needed. Metoprolol is excreted in breast milk in very small quantities. Caution should be exercised when Metoprolol is administered to a nursing woman.

Therapeutic
Poisoning due to an overdose of metoprolol may lead to severe hypotension, sinus bradycardia, atrioventricular block, heart failure, cardiogenic shock, cardiac arrest, bronchospasm, impairment of consciousness, coma, nausea, vomiting, cyanosis, hypoglycaemia and, occasionally, hyperkalaemia. The first manifestations usually appear 20 minutes to 2 hours after drug ingestion. Treatment: Treatment should include close monitoring of cardiovascular, respiratory and renal function, and blood glucose and electrolytes. Further absorption may be prevented by induction of vomiting, gastric lavage or administration of activated-charcoal if ingestion is recent. Cardiovascular complications should be treated symptomatically, which may require the use of sympathomimetic agents (e.g. noradrenaline, metaramionl), atropine or inotropic agents (e.g. dopamine, dobutamine). Temporary pacing may be required for AV block. Glucagon can reverse the effects of excessive B-blockade, given in a dose of 1-10 mg intravenously. Intravenous B2-stimulants e.g. terbutaline may be required to relieve bronchospasm. Metoprolol cannot be effectively removed by haemodialysis.
