Generic Metoprolol: An Overview
Metoprolol is part of a class of medicines called beta-adrenergic blocking agents, or
beta blockers for short. The drug helps to block a specific type of beta receptor called beta-1 receptors. By doing this, metoprolol causes the reverse effect of stress hormones, such as adrenaline (epinephrine). It decreases heart rate and both
systolic and diastolic blood pressure, as well as the workload of the heart, meaning that the heart requires less blood and oxygen to work properly.
Metoprolol is sold under the brand names
Lopressor® (immediate-release version) and
Toprol-XL® (extended-release version). Lopressor was originally developed by Novartis Pharmaceuticals, and
Toprol-XL was developed by AstraZeneca Pharmaceuticals. The patents for these medicines have expired, and generic versions are now available.
