Check out Dr. Peter Akpunonu, Assistant Professor of Emergency Medicine, and co-author’s Clinical Toxicology article, Highly potent fentanyl analogs: apnea from exposure to small quantities of ß-hydroxyfentanyl and furanylfentanyl, published online March 19, 2019.
“Fentanyl analogs are a heterogeneous class of opioids that include acetylfentanyl, alpha-methyl fentanyl, butyrfentanyl, carfentanil, sufentanil, ß-hydroxyfentanyl, and furanylfentanyl. Fentanyl analogs have been largely described in the United States as an adulterant in heroin and tablets. In the Pacific Northwest, the use of powdered fentanyl for insufflation has become increasingly common. We report cases of toxicity from intentional recreational exposure to the novel synthetic opioids furanylfentanyl, and intentional therapeutic use of ß-hydroxyfentanyl.” click here to read more
