Diprenorphine is considered the specific antagonist for etorphine and carfentanil,<ref>Jessup DA, Clark WE, Jones KR, Clark R, Lance WR.

''Journal of the American Veterinary Medical Association''. 1985 Dec 1;187(11):1253-4.</ref> and is normally used to remobilise animals once veterinary procedures have been completed,<ref>Alford BT, Burkhart RL, Johnson WP. Etorphine and diprenorphine as immobilizing and reversing agents in captive and free-ranging mammals. ''Journal of the American Veterinary Medical Association''. 1974 Apr 1;164(7):702-5.</ref>. Because diprenorphine also has some agonistic properties of its own, it should not be used on humans in the event that they are accidentally exposed to etorphine or carfentanil. Naloxone or naltrexone are the preferred human antagonists<ref>Caulkett NA, Arnemo JM. Chemical Immobilization of Free-Ranging Terrestrial Mammals. In: Tranquilli WJ, Thurmon JC, Grimm KA, eds.

In theory, diprenorphine could also be used as an antidote for treating overdose of certain opioid derivatives which are used in humans, such as ], for which the binding affinity is so high that naloxone does not reliably reverse the narcotic effects. However, diprenorphine is not generally available in hospitals; instead a vial of diprenorphine is supplied with etorphine or carfentanil specifically for reversing the effects of these drugs, so use of diprenorphine for treating e.g. a buprenorphine overdose is not carried out in practice, although it would work in theory. |
