It is an oxidized derivative of adrenaline and has no adrenaline-mimetic effect, so it does not affect blood pressure and heart rate, but it can enhance the resistance of capillaries to damage, stabilize the acidic mucopolysaccharides in blood vessels and surrounding tissues, reduce the permeability of capillaries, and enhance the retraction effect of damaged capillary ends, making it difficult for blood clots to fall off the tube wall, thereby shortening the hemostasis time, but it does not affect the coagulation process.

It produces direct pharmacological effects through hypertonic dehydration, eliminating brain edema, reducing brain water content, and lowering intracranial pressure; tissue dehydration and diuretic effects. It increases plasma osmotic pressure, reduces tissue edema, increases renal blood flow, reduces the reabsorption of water and electrolytes by the renal tubules, and promotes the excretion of certain drugs and poisons.
