Propranolol is a medication belonging to a class of drugs known as beta-blockers. It is primarily used to treat high blood pressure, anxiety, and certain heart conditions. By blocking the effects of adrenaline, it helps to reduce heart rate and lower blood pressure, making it easier for the heart to pump blood. In addition to its cardiovascular uses, Propranolol is often prescribed for migraine prevention and to manage symptoms of performance anxiety. It can also be used to treat tremors and certain types of irregular heartbeats. As with any medication, it is important to follow a healthcare provider's instructions when using Propranolol.
