What is epinephrine? ; Epinephrine, also called adrenaline, is both a hormone and a neurotransmitter. As a hormone, it’s made and released by your adrenal glands, which are hat-shaped glands that sit on top of each kidney. As a central nervous system neurotransmitter, it’s a chemical messenger that helps transmit nerve signals across nerve endings to another nerve cell, muscle cell or gland cell. Epinephrine is part of your sympathetic nervous system, which is part of your body’s emergency response system to danger — the “fight-or-fli ...

Epinephrine and norepinephrine sound alike, and they also share many of the same functions. Learn more about these two hormones and neurotransmitters, including the differences between them.
Background : The administration of epinephrine after severe refractory hypotension, shock, or cardiac arrest restores systemic blood flow and major vessel perfusion but may worsen cerebral microvascular perfusion and oxygen delivery through vasoconstriction. The authors hypothesized that epinephrine induces significant microvascular constriction in the brain, with increased severity after repetitive dosing and in the aged brain, eventually leading to tissue hypoxia. Methods : The authors investigated the effects of intravenous epinephrine admin ...
