Propranolol is an oral beta blocker prescribed mainly for cardiovascular conditions such as high blood pressure, angina, irregular heartbeat, and heart attack prevention. It is also utilized for managing symptoms of anxiety, reducing migraine frequency, controlling tremors, and treating thyroid-related disorders. By blocking beta-adrenergic receptors, propranolol slows the heart rate and decreases strain on the heart, thereby supporting its function and lowering blood pressure. This medication may occasionally be prescribed for other indications, like prophylaxis of migraine and certain types of birthmarks in infants, based on a healthcare provider’s evaluation.
