Overview: Beta blockers are drugs that make your heart beat slower and with less force.
Beta-adrenergic blocking agents, more commonly known as beta blockers, are drugs that slow the heart beat and reduce its force of contraction. Beta blockers do this by attaching (binding) to the sites that the hormone epinephrine binds to. You may know epinephrine as adrenaline.
Beta blockers have such names as atenolol, metoprolol, nadolol, propranolol, sotalol and others (names normally end in "ol").
