What is a common medication for lowering blood pressure?

Lopressor is a well-known medication for lowering blood pressure, specifically classified as a beta-blocker. Beta-blockers work by blocking the effects of epinephrine (adrenaline) on the body, which causes the heart to beat more slowly and with less force. This decrease in heart rate and the overall workload of the heart ultimately leads to lower blood pressure. Lopressor is often prescribed for conditions such as hypertension and can also help prevent angina (chest pain) and improve heart function after a heart attack.

In contrast, the other medications listed serve different purposes. Singulair is primarily used for managing asthma and allergies, Crestor is a statin used to lower cholesterol levels, and Proair HFA is a rescue inhaler used to relieve asthma or COPD symptoms. Therefore, these medications do not have the primary function of lowering blood pressure, making Lopressor the most appropriate choice in this context.
