Generic Name: metoprolol succinate er tablets

Over-the-Counter (OTC)

Brand Names:

Metoprolol Succinate

Metoprolol succinate ER tablets are a beta-1 selective adrenergic blocker in extended-release form indicated for treating hypertension, angina pectoris, and heart failure.

Overview

Metoprolol succinate ER tablets are a beta-1 selective adrenergic blocker in extended-release form indicated for treating hypertension, angina pectoris, and heart failure.

Uses

Indicated for treating hypertension, angina pectoris, and heart failure. For hypertension: lowers blood pressure to reduce risk of cardiovascular events. For angina: reduces attacks and improves exercise tolerance. For heart failure: reduces cardiovascular mortality and hospitalization risk.

Dosage

Administer once daily with titration at weekly or longer intervals as needed. Hypertension: starting 25-100 mg daily. Angina: starting 100 mg daily. Heart failure: starting 12.5-25 mg daily. Pediatric (6+ years): 1 mg/kg once daily maximum 50 mg initially. Maximum studied dose 400 mg daily.

Side Effects

Most common (>2%): tiredness, dizziness, depression, diarrhea, shortness of breath, bradycardia, and rash. Post-operative: increased bradycardia, hypotension, stroke, and death compared to placebo.

Interactions

Catecholamine-depleting drugs have additive effects. CYP2D6 inhibitors (quinidine, fluoxetine, paroxetine, propafenone) increase metoprolol concentrations. Digitalis glycosides, clonidine, diltiazem, verapamil increase bradycardia risk.

Warnings

Abrupt cessation may exacerbate myocardial ischemia. Risk of worsening heart failure during titration. Avoid in bronchospastic disease. Bradycardia risk with concomitant drugs. Pheochromocytoma requires alpha-blocker first. May mask hypoglycemia signs. Can precipitate thyroid storm if abruptly withdrawn. Contraindicated in severe bradycardia, second/third-degree heart block, cardiogenic shock, decompensated heart failure.

Pregnancy

Available data show no drug-associated birth defect risk, but inconsistent reports of growth restriction and preterm birth exist. Neonates exposed in utero may experience hypotension, hypoglycemia, bradycardia, respiratory depression. Metoprolol present in breast milk.

Storage

Store at 25 degrees C (77 degrees F); excursions permitted to 15-30 degrees C (59-86 degrees F).
