BETA BLOCKER
May 13th, 2008 . by editor
Beta blockers are common class of prescription drugs that neutralize the stimulatory effects of Adrenaline or epinephrine on beta receptors. These receptors are found in many tissues of the body like the nervous system and heart for example. When this beta receptors are stimulated, the heart beats faster and harder and the blood vessels constrict that results in an elevation of blood pressure. Beta blockers act by suppressing the stimulatory impulses that leads to a slowing of the pulse rate and reduction of blood pressure. Through the reduced workload of the heart, beta blockers can relieve symptoms of angina pectoris. Beta blockers have also been used in the treatment of migraine, as long as it is in a continuous or daily basis.
