How do beta blockers work?

August 14, 2019 0 By Bertrand Dibbert


Your heart pumps blood around your body
through a network of blood vessels, known as the circulatory system. Your blood then supplies the cells in your body with the oxygen and nutrients they need. If your doctor has prescribed you beta blockers, such as atenolol or bisoprolol, it may be because you have an abnormal heart rhythm or angina, or heart failure or had a heart attack. Beta blockers work by blocking the actions of hormones called adrenaline and noradrenaline. These hormones make the heart beat
faster and with more force. Blocking them makes your heart beat more slowly and with less force, which reduces your blood pressure and the strain on your heart.
