Selective Beta Blockers: A Comprehensive Overview

Selective beta blockers are a class of medications that selectively target beta-1 receptors in the heart and blood vessels. They are commonly used to treat a variety of cardiovascular conditions, including high blood pressure, chest pain, and heart failure.

How Selective Beta Blockers Work

Beta-1 receptors are located on the heart and blood vessels. When activated, these receptors cause the heart to beat faster and the blood vessels to constrict. Selective beta blockers block these receptors, which slows the heart rate and relaxes the blood vessels. This can help to lower blood pressure, reduce chest pain, and improve heart function.

Types of Selective Beta Blockers

There are several different types of selective beta blockers available, including:

• Acebutolol
• Atenolol
• Bisoprolol
• Metoprolol
• Nadolol
• Nebivolol
• Propranolol

The choice of which type of selective beta blocker to use depends on the individual patient's condition and needs.
