Detailed explanation-3: -For severe allergic reactions which lead to hypotension, epinephrine helps to increase blood flow through veins by constricting blood vessels. By binding to receptors on smooth muscles of the lungs, epinephrine helps to relax the muscles blocking the airways and allows breathing to return to normal.

Detailed explanation-4: -About Epinephrine The first-line treatment for anaphylaxis is epinephrine (adrenaline). It is available by prescription in an auto-injector. A delay in using epinephrine is common in severe food allergic reaction deaths. Epinephrine works to reverse the life-threatening symptoms.
