Both are beta blockers. Here is how Lopressor and Bystolic compare on class, mechanism, dosing, approval and supply.
1 IND ICATIONS AND USAGE LOPRESSOR 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 LOPRESSOR 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 pharma…
1. INDICATIONS AND USAGE BYSTOLIC is a beta-adrenergic blocking agent indicated for the treatment of hypertension, to lower blood pressure. Lowering blood pressure reduces the risk of fatal and nonfatal cardiovascular events, primarily strokes and myocardial infarctions. ( 1.1 ) 1.1 Hypertension BYSTOLIC is indicated for the treatment of hypertension, to lower blood pressure [see Clinical Studies ( 14.1 )]. BYSTOLIC may be used alone or in combination with other antihypertensive agents [see Drug Interactions ( 7 )]. Lowering blood pressure reduces the risk of fatal and nonfatal 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 the class to which this drug principally belongs. There are no controlled trials demonstrating risk reduction wi…
12.1 Mechanism of Action Metoprolol is a beta 1 -selective (cardioselective) adrenergic receptor blocking agent. This preferential effect is not absolute, however, and at higher plasma concentrations, metoprolol also inhibits beta 2 -adrenoreceptors, chiefly located in the bronchial and vascular musculature. Metoprolol has no intrinsic sympathomimetic activity, and membrane-stabilizing activity is detectable only at plasma concentrations much greater than required for beta-blockade. Animal and human experiments indicate that metoprolol slows the sinus rate and decreases AV nodal conduction. The relative beta 1 -selectivity of metoprolol has been confirmed by the following: (1) In normal sub…
12.1 Mechanism of Action The mechanism of action of the antihypertensive response of BYSTOLIC has not been definitively established. Possible factors that may be involved include: (1) decreased heart rate, (2) decreased myocardial contractility, (3) diminution of tonic sympathetic outflow to the periphery from cerebral vasomotor centers, (4) suppression of renin activity and (5) vasodilation and decreased peripheral vascular resistance.
Which medicine is right for a given person depends on their diagnosis, other conditions, other medicines, kidney and liver function, pregnancy, and cost or reimbursement — none of which this page knows. Two drugs in the same class are not automatically interchangeable. Never start, stop or switch a prescription medicine on the basis of a web page; that decision belongs to you and your clinician or pharmacist.
Class and summary text is written by the Priya Life Science editorial team. Label, mechanism, route, manufacturer and approval data come from the U.S. FDA via the openFDA API; shortage status from the FDA Drug Shortage Database. Approvals, indications and brand names differ between the US, EU/Ireland (EMA/HPRA) and other regions — a drug approved in one may not be approved, or may carry a different name, in another.
