Adrenergic Receptors, Mechanism Of Action, Side Effects, Summary

Beta-blockers are medications used primarily for treating high blood pressure. The usefulness of these medications rests on their ability to block the effects of a nervous system transmitter chemical known as norepinephrine and the related "fight-or-flight" hormone epinephrine. Beta-blockers are also used to treat heart-related chest pain (angina pectoris, or simply angina), abnormalities of heart rhythm, and certain other conditions.
