Butyr-fentanyl

Butyr-fentanyl Uses, Dosage, Side Effects, Food Interaction and all others data.

Butyr-fentanyl or butyrylfentanyl (not to be confused with 3-methylfentanyl) is a potent short-acting synthetic opioid analgesic drug. It is an analog of fentanyl with roughly 1/30 the potency. Butyr-fentanyl was first synthesized in 1961 by Janssen Pharmaceuticals as a new opioid analgesic.

Butyr-fentanyl has no current legitimate clinical applications, but anecdotal reports indicate it may occasionally be surfacing on the grey-market as a recreational drug. This compound is a schedule I controlled substance in the USA because it is a positional isomer of 3-Methylfentanyl.

The DEA in the United States has confirmed at least 40 fatalities involving butyrfentanyl before May 2016.
