Metoprolol tartrate is a beta-adrenergic blocker indicated for the treatment of: Hypertension, to lower blood pressure. Lowering blood pressure reduces the risk of fatal and non-fatal cardiovascular events, primarily strokes and myocardial infarctions. ( 1.1 ) Angina Pectoris. ( 1.2 ) Myocardial Infarction, to reduce the risk of cardiovascular mortality when used in conjunction with intravenous metoprolol therapy in patients with definite or suspected acute myocardial infarction in hemodynamically stable patients. ( 1.3 ) 1.1 Hypertension Metoprolol tartrate is indicated for the treatment of hypertension in adult patients, to lower blood pressure. Lowering blood pressure lowers the risk of fatal and non-fatal cardiovascular events, primarily strokes and myocardial infarctions. These benefits have been seen in controlled trials of antihypertensive drugs from a wide variety of pharmacologic classes including metoprolol. Control of high blood pressure should be part of comprehensive cardiovascular risk management, including, as appropriate, lipid control, diabetes management, antithrombotic therapy, smoking cessation, exercise, and limited sodium intake. Many patients will require more than 1 drug to achieve blood pressure goals. For specific advice on goals and management, see published guidelines, such as those of the National High Blood Pressure Education Program’s Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure (JNC). …

Metoprolol tartrate is contraindicated in severe bradycardia, second or third degree heart block, cardiogenic shock, systolic blood pressure <100, decompensated heart failure, sick sinus syndrome (unless a permanent pacemaker is in place), and in patients who are hypersensitive to any component of this product. Known hypersensitivity to product components. ( 4 ) Severe bradycardia: Greater than first degree heart block, or sick sinus syndrome without a pacemaker. ( 4 ) Cardiogenic shock or decompensated heart failure. ( 4 )

Abrupt cessation may exacerbate myocardial ischemia. ( 5.1 ) Heart Failure: Worsening cardiac failure may occur. ( 5.2 ) Bronchospastic Disease: Avoid beta-blockers. ( 5.3 ) Pheochromocytoma: Initiate therapy with an alpha blocker. ( 5.4 ) Major Surgery: Avoid initiation of high-dose extended-release metoprolol in patients undergoing non- cardiac surgery. Do not routinely withdraw chronic beta-blocker therapy prior to surgery. ( 5.5 , 6.1 ) Diabetes: May mask symptoms of hypoglycemia. ( 5.6 ) Thyrotoxicosis: Abrupt withdrawal in patients with thyrotoxicosis might precipitate a thyroid storm. ( 5.7 ) Peripheral Vascular Disease: Can aggravate symptoms of arterial insufficiency. ( 5.9 ) 5.1 Abrupt Cessation of Therapy Following abrupt cessation of therapy with certain beta-blocking agents, exacerbations of angina pectoris and, in some cases, myocardial infarction have occurred. When discontinuing chronically administered Metoprolol tartrate, particularly in patients with ischemic heart disease, gradually reduce the dosage over a period of 1 to 2 weeks and monitor the patient. If angina markedly worsens or acute coronary ischemia develops, promptly reinstate Metoprolol tartrate, and take measures appropriate for the management of unstable angina. Warn patients not to interrupt therapy without their physician’s advice. Because coronary artery disease is common and may be unrecognized, avoid abruptly discontinuing Metoprolol tartrate in patients treated only for hypertension. 5.2 …

Hepatic Impairment: Consider initiating Metoprolol tartrate therapy at low doses and gradually increase dosage to optimize therapy, while monitoring closely for adverse events. ( 8.6 ) 8.1 Pregnancy Risk Summary Available data from published observational studies have not demonstrated an association of adverse developmental outcomes with maternal use of metoprolol during pregnancy (see Data ) . Untreated hypertension and myocardial infarction during pregnancy can lead to adverse outcomes for the mother and the fetus (see Clinical Considerations ). In animal reproduction studies, metoprolol has been shown to increase post- implantation loss and decrease neonatal survival in rats at oral …
