L(-)-Epinephrine Summary: epinephrine (adrenaline, epinephrine, capital abbreviations are: A or E) is the main hormone of the adrenal medulla, the biosynthesis mainly in the medulla chromaffin cells norepinephrine first formed, then further through phenethylamine -N- methyl transferase (phenylethanolamine N-methyl transferase, PNMT) the role of the norepinephrine methylated form of adrenaline.
L(-)-Epinephrine Usage: non-steroidal hormone drugs, also used as a hemostatic Adrenosem intermediates. Mainly used for anaphylactic shock, bronchial asthma and cardiac arrest rescue. The main clinical use of cardiac arrest, bronchial asthma, anaphylactic shock, but also treat hives, hay fever and nasal or gum bleeding.
L(-)-Epinephrine Mechanism: the direct effect of the product on the adrenergic α, β receptors, resulting in rapid and brief strong excitement α and β-type effect on the heart β1- receptors excited, can enhance myocardial contractility, heart rate, cardiac increased oxygen consumption. At the same effect on vascular smooth muscle β2- receptor, blood vessels dilate, reduce peripheral vascular resistance and reduced diastolic blood pressure. Β2- excited receptors in bronchial smooth muscle relaxation, bronchodilation, relieve bronchial spasm; for α- receptor stimulant, the skin, mucosal vascular and visceral small blood vessels.
