Penbutolol

Penbutolol (pronounced: pen-byoo-toh-lol) is a beta blocker medication primarily used in the treatment of hypertension (high blood pressure). It is also sometimes used to treat angina pectoris and arrhythmia.

Etymology

The term "Penbutolol" is derived from its chemical structure. The prefix "Pen" is short for "Pentyl", referring to the five carbon atoms in the molecule. "But" refers to the four carbon atoms in the butyl group, and "olol" is a common suffix for beta blockers.

Usage

Penbutolol works by blocking the action of certain natural chemicals in your body, such as epinephrine, on the heart and blood vessels. This effect reduces heart rate, blood pressure, and strain on the heart.
