adrenaline (epinephrine) (ă-dren-ă-lin) n. an important hormone secreted by the medulla of the adrenal gland. It has widespread effects on circulation, the muscles, and sugar metabolism. The action of the heart is increased, the rate and depth of breathing are increased, and the metabolic rate is raised; the force of muscular contraction improves and the onset of muscular fatigue is delayed. At the same time the blood supply to the bladder and intestines is reduced, their muscular walls relax, and the sphincters contract. Adrenaline is administered by injection for the emergency treatment of anaphylaxis and cardiac arrest. It is also included in some local anaesthetic solutions, particularly those used in dentistry, to prolong anaesthesia, and is used as eye drops in treating glaucoma.
