What is this medication?

Metoprolol, Lopressor
Antihypertensive/antianginal Agent, Blocks Beta 1 adrenergic receptors with little effect on Beta 2

Metoprolol/Lopressor is officially indicated for hypertension, angina, heart failure with reduced ejection fraction, and myocardial infarction (early treatment and future prevention).  It is also commonly prescribed off-label for atrial fibrillation/flutter, migraine prophylaxis, supraventricular tachycardia, thyrotoxicosis, and ventricular arrhythmia.

“ALERT: US Boxed Warning

Ischemic heart disease:
Following abrupt cessation of therapy with certain beta-blocking agents, exacerbations of angina pectoris and, in some cases, myocardial infarction (MI) have occurred. When discontinuing chronically administered metoprolol, particularly in patients with ischemic heart disease, gradually reduce the dosage over a period of 1 to 2 weeks and carefully monitor the patient. If angina markedly worsens or acute coronary insufficiency develops, reinstate metoprolol administration promptly, at least temporarily, and take other measures appropriate for the management of unstable angina. Warn patients against interruption or discontinuation of therapy without their health care provider’s advice. Because coronary artery disease is common and may be unrecognized, it may be prudent not to discontinue metoprolol therapy abruptly, even in patients treated only for hypertension.”

How does this medication work? 

Beta 1 receptor is activated by adrenaline and is involved with cardiac output by increasing the volume of each pump as well as increasing the heart rate.  Metoprolol/Lopressor works by blocking this receptor having the reverse effect thereby reducing heart rate and stroke volume.
