Beta blockers are prescription medications that reduce the workload of the heart and lower blood pressure. They are commonly prescribed to relieve angina (a certain type of chest pain, pressure or discomfort) or to treat heart failure. They are ... prescribed for people who have high blood pressure (hypertension).

Beta blockers reduce blood pressure. Beta blockers work by blocking the effects of the hormone epinephrine... known as adrenaline. As a result, the heart beats more slowly and with less force, thereby reducing blood pressure. Beta blockers also help blood vessels relax and open up to improve blood flow.

Beta-blockers can be used to treat some types of heart disease. Beta-blockers improve the heart's ability to relax, decrease the production of harmful substances produced by the body in response to heart failure and slow the heart rate. Over time, beta-blockers improve the heart's pumping ability.
