Overview

Metoprolol tartrate (tablet) is a anti-anginal, antiarrhythmic, beta-adrenergic blocker that is FDA approved for the {{{indicationType}}} of acute myocardial infarction (AMI). Common adverse reactions include bradyarrhythmia, constipation, depression, diarrhea, dizziness, dyspnea, fatigue, headache, heart block, heart failure, hypotension, indigestion, nausea, pruritus, rash, and wheezing.

Adult Indications and Dosage

FDA-Labeled Indications and Dosage (Adult)

Hypertension
  • Dosing Information
  • Individualize the dosage of Lopressor tablets. Lopressor tablets should be taken with or immediately following meals.
  • The usual initial dosage of Lopressor tablets is 100 mg daily in single or divided doses, whether used alone or added to a diuretic. Increase the dosage at weekly (or longer) intervals until optimum blood pressure reduction is achieved. In general, the maximum effect of any given dosage level will be apparent after 1 week of therapy. The effective dosage range of Lopressor tablets is 100-450 mg per day. Dosages above 450 mg per day have not been studied. While once-daily dosing is effective and can maintain a reduction in blood pressure throughout the day, lower doses (especially 100 mg) may not maintain a full effect at the end of the 24-hour period, and larger or more frequent daily doses may be required. This can be evaluated by measuring blood pressure near the end of the dosing interval to determine whether satisfactory control is being maintained throughout the day. Beta1 selectivity diminishes as the dose of Lopressor is increased.
Angina Pectoris
  • Dosing Information
  • The dosage of Lopressor tablets should be individualized. Lopressor tablets should be taken with or immediately following meals.
  • The usual initial dosage of Lopressor tablets is 100 mg daily, given in two divided doses. gradually increase the dosage at weekly intervals until optimum clinical response has been obtained or there is pronounced slowing of the heart rate. The effective dosage range of Lopressor tablets is 100-400 mg per day. Dosages above 400 mg per day have not been studied. If treatment is to be discontinued, gradually decrease the dosage over a period of 1-2 weeks
Myocardial Infarction
  • Dosing information
  • Early treatment:
  • During the early phase of definite or suspected acute myocardial infarction, initiate treatment with Lopressor as soon as possible after the patient's arrival in the hospital. Such treatment should be initiated in a coronary care or similar unit immediately after the patient's hemodynamic condition has stabilized.
  • Begin treatment in this early phase with the intravenous administration of three bolus injections of 5 mg of Lopressor each; give the injections at approximately 2-minute intervals. During the intravenous administration of Lopressor, monitor blood pressure, heart rate, and electrocardiogram.
  • In patients who tolerate the full intravenous dose (15 mg), initiate Lopressor tablets, 50 mg every 6 hours, 15 minutes after the last intravenous dose and continue for 48 hours. Thereafter, the maintenance dosage is 100 mg twice daily.
  • Start patients who appear not to tolerate the full intravenous dose on Lopressor tablets either 25 mg or 50 mg every 6 hours (depending on the degree of intolerance) 15 minutes after the last intravenous dose or as soon as their clinical condition allows. In patients with severe intolerance, discontinue Lopressor.
  • Late treatment: Start patients with contraindications to treatment during the early phase of suspected or definite myocardial infarction, patients who appear not to tolerate the full early treatment, and patients in whom the physician wishes to delay therapy for any other reason on Lopressor tablets, 100 mg twice daily, as soon as their clinical condition allows. Continue therapy for at least 3 months. Although the efficacy of Lopressor beyond 3 months has not been conclusively established, data from studies with other beta blockers suggest that treatment should be continued for 1-3 years.

Off-Label Use and Dosage (Adult)

Guideline-Supported Use

Atrial Fibrillation, Rate Control
  • Dosing Information
Acute Setting: Lopressor injection 2.5—5 mg IV bolus over 2 min; up to 3 doses[1]

In the absence of preexcitation, intravenous administration of beta blockers (esmolol, metoprolol, or propranolol) or nondihydropyridine calcium channel antagonists (verapamil, diltiazem) is recommended to slow the ventricular response to atrial fibrillation in the acute setting, exercising caution in patients with hypotension or heart failure.[2]

Non–Guideline-Supported Use

Atrial flutter
  • Dosing Information
Lopressor injection dose range: 2—15 mg[3]
Multifocal atrial tachycardia
  • Dosing Information
Lopressor injection dose range: 2—15 mg[3]
Supraventricular Tachycardia
  • Dosing Information
Lopressor injection dose range: 2—15 mg[3]
Aggressive Behavior
Injection Site Pain Associated with Propofol Use
  • Dosing Information
Pretreatment with Lopressor injection 2 mg.[4]

Contraindications

Warnings

Heart Failure

Beta blockers, like Lopressor, can cause depression of myocardial contractility and may precipitate heart failure and cardiogenic shock. If signs or symptoms of heart failure develop, treat the patient according to recommended guidelines. It may be necessary to lower the dose of Lopressor or to discontinue it.

Ischemic Heart Disease

Do not abruptly discontinue Lopressor therapy in patients with coronary artery disease. Severe exacerbation of angina, myocardial infarction and ventricular arrhythmias have been reported in patients with coronary artery disease following the abrupt discontinuation of therapy with beta-blockers. When discontinuing chronically administered Lopressor, particularly in patients with coronary artery disease, the dosage should be gradually reduced over a period of 1-2 weeks and the patient should be carefully monitored. If angina markedly worsens or acute coronary insufficiency develops, Lopressor administration should be reinstated promptly, at least temporarily, and other measures appropriate for the management of unstable angina should be taken. Patients should be warned against interruption or discontinuation of therapy without the physician's advice. Because coronary artery disease is common and may be unrecognized, it may be prudent not to discontinue Lopressor therapy abruptly even in patients treated only for hypertension.

Use During Major Surgery

Chronically administered beta-blocking therapy should not be routinely withdrawn prior to major surgery; however, the impaired ability of the heart to respond to reflex adrenergic stimuli may augment the risks of general anesthesia and surgical procedures.

Bradycardia

Bradycardia, including sinus pause, heart block, and cardiac arrest have occurred with the use of Lopressor. Patients with first-degree atrioventricular block, sinus node dysfunction, or conduction disorders may be at increased risk. Monitor heart rate and heart rhythm in patients receiving Lopressor. If severe bradycardia develops, reduce or stop Lopressor.

Exacerbation of Bronchospastic Disease

Patients with bronchospastic disease,should, in general, not receive beta blockers, including Lopressor. Because of its relative beta1 selectivity, however, Lopressor may be used in patients with bronchospastic disease who do not respond to, or cannot tolerate, other antihypertensive treatment. Because beta1 selectivity is not absolute use the lowest possible dose of Lopressor and consider administering Lopressor in smaller doses three times daily, instead of larger doses two times daily, to avoid the higher plasma levels associated with the longer dosing interval. Bronchodilators, including beta2 agonists, should be readily available or administered concomitantly.

Diabetes and Hypoglycemia

Beta blockers may mask tachycardia occurring with hypoglycemia, but other manifestations such as dizziness and sweating may not be significantly affected.

Pheochromocytoma

If Lopressor is used in the setting of pheochromocytoma, it should be given in combination with an alpha blocker, and only after the alpha blocker has been initiated. Administration of beta blockers alone in the setting of pheochromocytoma has been associated with a paradoxical increase in blood pressure due to the attenuation of beta-mediated vasodilatation in skeletal muscle.

Thyrotoxicosis

Lopressor may mask certain clinical signs (e.g., tachycardia) of hyperthyroidism. Avoid abrupt withdrawal of beta blockade, which might precipitate a thyroid storm.
