Beta blockers are medications used for cardiac pathologies. They are prescribed in cases of cardiac deficiency
(especially after a myocardial infarction
) and cardiac arrhythmia
. Their principal action is to induce a blockage of adrenergic mediator receptors of catecholamines (such as adrenaline). They result in reduced contraction of the cardiac muscle, a reduced pulse rate, and diminished production of renin (a hormone involved in the regulation of arterial blood pressure).
