What Is Propranolol?

Propranolol is a widely used medication belonging to a class of drugs called beta-blockers. It has been prescribed for decades to treat heart-related conditions, migraine headaches, and even anxiety. Because it blocks the effects of adrenaline, Propranolol helps calm the body, reduce heart rate, and lower blood pressure.

Brief History & Development

Developed in the 1960s, Propranolol was one of the very first beta-blockers ever introduced. It transformed modern heart treatment approaches by giving doctors the ability to regulate abnormal heart signals safely and effectively.

How It Works in the Body

Propranolol works by blocking beta-receptors in the heart and the sympathetic nervous system. This prevents adrenaline from overstimulating the body, leading to lowered stress responses, reduced blood pressure, and steadier heart rhythms. This mechanism also makes Propranolol helpful for anxiety.

Performance Anxiety Benefits
