The WHO Secretariat would like to thank the following people for their contribution in producing this review report: Dr. Katia Gysling, Chile (literature search, review and drafting), Dr. Dilkushi Poovendran, Geneva, Switzerland (questionnaire analysis and report drafting) and Dr. Stephanie Kershaw, Adelaide, Australia (review report editing, questionnaire analysis and report drafting). WHO would like to thank the European Monitoring Centre for Drugs and Drug Addiction (EMCDDA) for providing information on Furanyl Fentanyl from the European Union Early Warning System, which includes data reported by the Reitox National Focal Points in the EU Member States, Turkey, and Norway. Page 5 of 16 39th ECDD (2017) Agenda item 4.6 Furanyl fentanyl Summary Furanyl Fentanyl is a new designer opioid drug. It is a derivative of fentanyl with two distinctive characteristics: 1) higher liposolubility that allows its rapid absorption into general circulation 2) It binds to µ-opioid receptors with significant higher affinity than morphine. These characteristics give furanyl fentanyl a highly risky pharmacological profile. In the last several years there has been an increase in deaths due to the use of this designer opioid. Furthermore, it has been reported that it might be present in cocaine crack and other illicit drugs sold on the black market. Page 6 of 16 39th ECDD (2017) Agenda item 4.6 Furanyl fentanyl 1.
