Adrenorfin (metorfamid) je endogeni, C-terminalno amidisani, opioidni oktapeptid (Tyr-Gly-Gly-Phe-Met-Arg-Arg-Val-NH2). On nastaje proteolitičim presecanjem proenkefalina A. Adrenorfin je široko rasprostranjen u mozgu sisara.[3][4][5][6][7]
Dobio je ime po činjenici da je originalno nađen u humanom feohromocitomnom tumoru izvedenom iz srži nadbubrežne žlezde. Naknadno je utvrđeno da je isto tako prisutan u normalnoj humanoj i goveđoj adrenalnoj meduli.[3] Adrenorfin ima potentno opioidno dejstvo. On deluje kao balansirani agonist μ- i κ-opioidnog receptora, a nema efekta na δ-opioidne receptore.[4] On ispoljava analgetičke i respiratorno depresantske efekte.[8]
