Etorphine is an alcohol and a morphinane alkaloid. It has a role as an opioid analgesic, a sedative and an opioid receptor agonist.

Etorphine is a DEA Schedule I controlled substance. Substances in the DEA Schedule I have no currently accepted medical use in the United States, a lack of accepted safety for use under medical supervision, and a high potential for abuse. Etorphine (also called M-99, aka what is used in the popular show Dexter) is a narcotic analgesic morphinan used as a sedative in veterinary practice. In certain countries, etorphine is classified as a Schedule 1 drug and hence, in these countries, it can be used legally only by health professionals and for research purposes. Etorphine is only available to the patients under an official prescription. In the US, Etorphine is listed as a Schedule I drug, although Etorphine hydrochloride is classified as Schedule II.
