Carfentanil or carfentanyl, formerly sold under the brand name Wildnil, is an extremely potent opioid analgesic formerly used in veterinary medicine to anesthetize large animals such as elephants and rhinoceroses. It is a structural analogue of the synthetic opioid analgesic fentanyl. It is typically administered in this context by tranquilizer dart. Carfentanil has also been used in humans to image opioid receptors. It has additionally been used as a recreational drug, typically by injection, insufflation, or inhalation. Deaths have been reported in association with carfentanil.
