Propranolol

Uses

Propranolol Uses Propranolol is used in the treatment of angina (heart-related chest pain), arrhythmia, heart attack, hypertension (high blood pressure), anxiety, tremors, glaucoma, heart failure, migraine, prevention of migraine, and pheochromocytoma.

How it Works

How Propranolol works Propranolol is a beta blocker that affects the body’s response to nerve impulses, particularly in the heart. It slows down the heart rate and facilitates the heart's ability to pump blood throughout the body. This action helps prevent arrhythmias, stabilizes blood pressure, and reduces the risk of heart attacks. Additionally, it dilates blood vessels to improve blood flow, thereby preventing angina and migraines. The precise mechanism by which it prevents tremors is not fully understood, but experts believe that Propranolol may help block nerve impulses to the muscles responsible for tremors. It also counteracts the effects of the chemical messengers, adrenaline and noradrenaline, produced by the brain, which are known to increase heart rate and contribute to feelings of anxiety. Thus, Propranolol can aid in managing anxiety. In the treatment of pheochromocytoma, Propranolol may be administered to inhibit the action of high levels of adrenaline, reducing the risk of dangerously high blood pressure during surgery to remove the tumor.

Side Effects

Common side effects of Propranolol include slow heart rate, nightmares, cold extremities, sleep disturbances, and fatigue.
