Mechanism Of Action:

Beta blockers, also called beta-adrenergic blocking agents, inhibit the release of the adrenaline and noradrenaline in certain parts of the body. This results in a slowing of the heart rate and reduces the force at which blood is pumped around your body. Beta-blockers are drugs which make your heart beat more slowly and with less force.

Beta-blockers can also block angiotensin II In the kidney which results in lowering the blood pressure.
