Acetylfentanyl is a synthetic opioid analgesic that is an analog of fentanyl. It is a potent agonist of the mu-opioid receptor and has been associated with numerous overdose deaths.

Chemical structure and properties

Acetylfentanyl is chemically similar to fentanyl, with the primary difference being the presence of an acetyl group in place of the propionyl group found in fentanyl. Its IUPAC name is N-Phenyl-N-[1-(2-phenylethyl)piperidin-4-yl]acetamide. The molecular formula is C21H26N2O.

Pharmacology

Acetylfentanyl acts as a potent agonist at the mu-opioid receptor, which is responsible for its analgesic and euphoric effects. It is estimated to be 5 to 15 times more potent than heroin and about 80 times more potent than morphine. The drug's high potency increases the risk of overdose and respiratory depression.

Medical use

Acetylfentanyl has no approved medical use and is not prescribed for any condition. It is often encountered as a designer drug and is sometimes found in illicit drug supplies, either alone or mixed with other substances.

Legal status

The legal status of acetylfentanyl varies by country. In many jurisdictions, it is classified as a controlled substance due to its high potential for abuse and lack of accepted medical use. For example, in the United States, it is classified as a Schedule I substance under the Controlled Substances Act.

Health risks

The primary health risks associated with acetylfentanyl are related to its potency and potential for overdose. Symptoms of overdose may include severe respiratory depression, sedation, coma, and death. Naloxone can be used to reverse the effects of an acetylfentanyl overdose, but multiple doses may be required due to the drug's potency.
