Epinephrine belongs to a class of drugs known as alpha- and beta-adrenergic agonists (sympathomimetic agents). It acts by relaxing the airway muscles and constricting the blood vessels. Epinephrine injection is used to treat severe allergic responses (including anaphylaxis) to insect bites or stings, drugs, foods, or other substances in an emergency.
It is also used to treat anaphylaxis caused by unknown chemicals or exercise-induced anaphylaxis. Epinephrine acts swiftly to enhance breathing, accelerate the heart, boost blood pressure, reverse hives, and reduce swelling of the face, lips, and throat.
Increased vascular smooth muscle contraction, pupillary dilator muscle contraction, and intestinal sphincter muscle contraction are all caused by epinephrine. Other noteworthy effects include increased heart rate, myocardial contractility, and beta-1 receptor-mediated renin release.
