What is epinephrine auto-injector, and how does it work (mechanism of action)?
- EpiPen is an auto-injectable epinephrine-containing device used for self-administration during life-threatening allergic reactions, including anaphylaxis. Epinephrine, the medicine contained in EpiPen, is an excitatory chemical naturally made by our bodies. Epinephrine stimulates alpha and beta-adrenergic receptors found throughout the body. When injected during an allergic reaction, epinephrine works in multiple ways to treat the many signs of anaphylaxis. It causes blood vessels to constrict or tighten which helps to increase blood pressure and decrease swelling. Epinephrine also stimulates the heart muscle, causing the heart to beat faster and pump more blood to the vital organs. Epinephrine helps patients breathe better by relaxing the muscles in the lungs and allowing the airways to open up. Additionally, it also helps to prevent further release of inflammatory chemicals that were triggered by the initial allergic reaction.
- The FDA approved EpiPen in December 1987.
