Mechanism of Hormone Action - PowerPoint PPT Presentation Adrenaline, also known as epinephrine, is a hormone and medication which is involved in regulating visceral functions (e.g., respiration). Epinephrine works by reversing the symptoms of anaphylaxis. Adrenaline is a hormone produced within the adrenal gland in response to stress that increases heart rate, strengthens the force of the heart's contraction and cardiac output, increases blood pressure and opens up the bronchioles in the lungs, and raises the blood levels of glucose and lipids among other effects. Epinephrine is a sympathomimetic catecholamine that exerts its pharmacologic effects on both alpha and beta-adrenergic receptors using a G protein-linked second messenger system. Epinephrine acts on both alpha and beta-adrenergic receptors. The drug may cause decreased renal perfusion.

Adrenaline is an endogenous catecholamine, a sympathomimetic drug with little receptor selectivity. Myburg (2008) - "The case for Adrenaline" Critical Care and Resuscitation, Volume 10 (3) page 178. poor quality . In its role as a haemodynamic support infusion, adrenaline acts as an inodilator, increasing cardiac output and increasing blood pressure while decreasing the afterload (mainly by its effect on the arterioles of the skeletal muscle). Accidental injection of high dose (1:1,000) epinephrine contained in epinephrine autoinjectors into fingers or thumb can produce prolonged tissue ischemia, reperfusion pain, and in some cases traumatic nerve injury (neuropraxia) lasting as long as 8-10 weeks (Fitzcharles-Bowe et al, 2007; Mathez et al, 2009).
