Beta blockers are a type of medicine used to treat high blood pressure. Commonly used beta blockers are atenolol, metoprolol and propranolol. By reducing a patient's blood pressure beta blockers can reduce the risk of heart attacks and strokes.
Research has found that beta blockers work just as well as newer medicines. In older people beta blockers may not prevent as many strokes as other medicines, but they are still good for treating high blood pressure.
Many people need more than one medicine to control their blood pressure. Beta blockers are therefore often used with other medicines.
