by Drugs.com
Epinephrine works by activating both alpha and beta receptors found in your body in response to a severe allergy (called anaphylaxis). By acting on alpha receptors, it helps to maintain your blood pressure and heart function, and by acting on beta receptors, it relaxes your lung airways to help relieve shortness of breath and wheezing.
