Levatol Uses

What Is Levatol Used For?

Levatol^® (penbutolol sulfate) is a prescription medication approved for the treatment of high blood pressure (hypertension). It belongs to a group of medications known as beta blockers. It can be used alone or in combination with other blood pressure medications. In particular, Levatol is often used in combination with thiazide diuretics (a certain type of "water pill").

 

In clinical studies, Levatol has been shown to significantly reduce blood pressure. By lowering blood pressure, medications such as this are thought to decrease the risks that occur with long-term high blood pressure (see Effects of High Blood Pressure). Levatol does not, however, cure high blood pressure.

 

How Does It Work?

Levatol belongs to a group of drugs called beta-adrenergic blocking agents, more often known as beta blockers. As the name implies, these medications block beta receptors in the body. In addition to blocking beta receptors, however, Levatol also slightly stimulates the beta receptors. 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.
