In general beta blockers enhance the heart's ability to relax.


Beta blockers work by blocking the effects of epinephrine and slowing the heart's rate, thereby decreasing the heart's demand for oxygen.

Too much adrenaline can lead to rapid heartbeat, high blood pressure, excessive sweating, anxiety, and palpitations. Blocking the release of these hormones, blockers decrease the oxygen demands and reduce stress on the heart. This lowers the force of the contractions of the heart muscles, and of blood vessels in the heart, the brain and the rest of the body.
