Many people are more familiar with opioid drugs and the brand names of this category of medications that are frequently offered and marketed. The lesser known analgesics of the opioid drug are also important to be aware of, particularly if working in a field in which these substances are used and/or prepared.

Etorphine is type of opioid analgesic that is semi-synthetic. Unlike other opioid drugs that are prepared from the substance that generally occurs in the opium poppy extract, Etorphine was originally prepared from oripavine, or the “poppy straw” in related opioid plants, Papaver bracteatum and Papaver orientale.

Conventional Uses of Etorphine

The potency of Etorphine is approximately 1000 times that of morphine and is typically given to mammals via a projectile syringe dart. Outside of use in a general veterinary practice, qualified health professionals and pharmacists who are authorized to handle the substance may also use Etorhpine for research purposes.

This substance is listed as a Schedule 1 drug in the United States and is not typically manufactured in the country. Outside supplies of this substance are usually imported from the United Kingdom and/or Germany for veterinary purposes.

Misuse of Etorphine

Trafficking or manufacturing of the substance without authorization can lead to not only legal difficulties but potential for misuse as well. If you or someone you know has had possession of the drug or any form of it, it is important to seek out professional help and assistance immediately.

High incidences of side effects have been observed with the use of large mammals in veterinary practices and can undoubtedly prove fatal with accidental human ingestion. Qualified health professionals, as with all drugs and substances, should regulate Etorphine, only.
