- Acute Myocardial Infarction: It is also indicated for the treatment of acute myocardial infarction (heart attack) to reduce cardiovascular mortality.
Lopressor belongs to a class of drugs known as beta-blockers, which work by blocking the effects of adrenaline on the heart and blood vessels, thereby slowing the heart rate, reducing blood pressure, and improving heart function.
