Propranolol is used for the treatment of high blood pressure, irregular heart rate, pheochromocytoma, some kinds of tremor and hypertrophic obstructive stenosis (heart muscle disease). Propranolol is also used for the prevention of angina (chest pain), migraine, headache and rehabilitation after the heart attack. Propranolol belongs to the class of beta-blockers. It works by relaxation of blood vessels and slowing the heart rate, which improves blood circulation and reduces blood pressure.
High blood pressure can result in the damage of brain, heart, blood vessels, kidneys and other organs, which in its turn can cause heart disease, infarction, cardiac insufficiency, stroke, kidney failure, loss of vision and other problems. In addition to the use of drugs, the changes of lifestyle also help to control the blood pressure. These changes include the low-fat and low-sodium diets, maintaining healthy weight, physical activities (at least 30 minutes every day), giving up smoking and alcohol abuse.
Main contraindications every patient should be aware of (not all of them are identical for all beta-blockers):

Arterial hypotension- systolic (upper) blood pressure less than 100-90 mm Hg.
