Atenolol is a medicine which is used in heart rhythm disorders, hypertension, angina and heart attacks.

Mechanism of action:

Aenolol tablets contain atenolol, which belongs to a group of medications called beta blockers. It is a selective beta-receptor antagonist, which means that it blocks the action of chemicals like adrenaline (epinephrine) that are released by the adrenal glands in response to nerve stimulation (for example due to stress) and work via beta-receptors to increase heart rate and constrict (narrow) blood vessels, amongst many other actions. Beta-receptors are found in many tissues, particularly the heart, kidneys, vascular smooth muscle in blood vessel walls, lung, skeletal muscle and liver. Atenolol in Atenolol tablets 50mg works by blocking stimulation of beta-receptors by adrenaline, which slows the heart rate and dilates (widens) blood vessels. This lowers blood pressure and increases blood flow and oxygen to the heart, which ...
... in turn decreases demand by the heart for oxygen, reduces the amount of work the heart has to do and helps the heart beat more regularly. All short-term and long-term symptom relief due to taking Atenolol is based on blocking beta-receptors in the target tissue.
