Propranolol is widely used in the medical field to treat various conditions. It is primarily prescribed to manage high blood pressure, helping to reduce the risk of heart attacks and strokes. Additionally, it is effective in controlling irregular heartbeats (arrhythmias) and preventing chest pain (angina) by easing the heart's workload.

Beyond cardiovascular issues, propranolol is also utilized to manage symptoms of anxiety, such as stage fright or performance anxiety, by reducing physical symptoms like trembling and rapid heartbeat. It is sometimes prescribed for migraines to prevent their occurrence or lessen their severity.

In rare cases, propranolol is used to treat certain types of tremors or to manage symptoms of hyperthyroidism, such as rapid heart rate. Its versatility in addressing both physical and psychological conditions makes it a valuable medication in clinical practice.
