Propranolol

About propranolol

This belongs to the group of medicines known as beta-blockers. Propranolol is used to treat a number of different problems.
High Blood Pressure: Propranolol slows down the activity of the heart, decreasing blood pressure.
Angina: Propranolol slows down the activity of the heart and reduces the heart's need for oxygen. This makes angina attacks less likely to occur.
Irregular Heartbeat: Normally the heartbeat is regulated by special tissues which conduct electricity. Some cases of irregular heartbeat are caused by these tissues conducting electricity too quickly. Propranolol works by reducing over-activity in the conducting tissue.
Anxiety: Anxiety can cause physical symptoms such as fast heartbeat, palpitations and trembling. Propranolol slows the heart rate to relieve these symptoms. (This medicine does not relieve the emotional symptoms associated with anxiety such as stress or fear, these symptoms should be treated separately).
Thyroid Problems: An overactive thyroid gland causes symptoms such as a fast or pounding heartbeat, trembling and sweating. Propranolol relieves these symptoms quickly, while anti-thyroid treatment takes effect (this may be several weeks).
Protecting the heart: Taking beta-blockers after having a heart attack has been shown, in some patients, to reduce the risk of a second attack.
Migraine: The pain of a migraine attack is usually due to widening of the blood vessels on the surface of the brain. Propranolol prevents this widening and thus prevents attacks.
