Uses
Propranolol is a medication belonging to a class of drugs known as beta-blockers. It is commonly prescribed by healthcare professionals to treat various conditions including:
- High blood pressure (hypertension)
- Angina (chest pain)

Propranolol works by blocking the effects of adrenaline, thus reducing the workload on the heart and decreasing blood pressure. By slowing down the heart rate, it can also relieve symptoms related to anxiety and stress.
