What is Labetalol?
Labetalol is a prescription medication primarily used to manage high blood pressure (hypertension). It belongs to a class of drugs called beta-blockers, which help reduce heart rate and relax blood vessels, allowing blood to flow more easily.
By lowering blood pressure, Labetalol helps decrease the risk of serious health issues such as heart attack, stroke, and kidney damage.
How Labetalol Works
Labetalol works by blocking specific receptors in the body that affect heart activity and blood vessels. This action:
- Slows down the heart rate
- Reduces the force of heart contractions
- Widens blood vessels
As a result, blood pressure drops and the heart works more efficiently.
