Blood Pressure Home > Levatol

Levatol is licensed for the treatment of high blood pressure. It comes in tablet form and is taken by mouth, typically once a day. This prescription drug belongs to a class of medications known as beta blockers, which help to lower blood pressure by blocking beta receptors throughout the body. Potential side effects include dizziness, fatigue, and nausea.

What Is Levatol?

How Does It Work?

Levatol belongs to a group of drugs called beta-adrenergic blocking agents, known as beta blockers for short. As you might guess, these medications block beta receptors in the body. In addition to blocking beta receptors, however, Levatol also slightly stimulates them. Only a few beta blockers do this; this slight stimulatory action is known as "intrinsic sympathomimetic activity" or ISA.
Beta receptors are located in a number of places within the body, including the heart and blood vessels. Stress hormones (such as adrenaline) bind to these receptors and cause certain reactions in the body, such as:
By blocking beta receptors, Levatol causes the reverse effect of stress hormones and reduces blood pressure. It may have less effect on heart rate and the workload of the heart compared to most other beta blockers, due to the fact that it slightly stimulates the beta receptors.
