How Labetalol Works

Labetalol works by blocking specific receptors in the body, known as beta-adrenergic receptors. This action helps to slow down the heart rate and reduce the force of the heart’s contractions.

By relaxing the blood vessels, labetalol helps to lower blood pressure, making it easier for the heart to pump blood throughout the body.

This dual action on heart rate and blood vessels makes it effective in managing high blood pressure.
