WebCatecholamine release is mediated through changes in sympathetic nervous system, being increased during stress and hypoglycemia. Catecholamines inhibit insulin secretion while decreasing insulin action. WebThe release of Catecholamines into the blood has a number of effects including increased energy, dilated pupils, increased blood pressure, increased heart rate and heightened metabolism. Typically, once the source of the stress has passed, Catecholamines are quickly metabolized and removed from the body through the urine.

WebUnder physiologic conditions, infusing catecholamine is associated with enhanced rates of aerobic glycolysis (resulting in adenosine triphosphate production), glucose release (both from glycogenolysis and gluconeogenesis), and inhibition of insulin-mediated glycogenesis.
