Fluetonitazene (fluornitrazene, F-etonitazene, 2-fluoroetonitazene) is a benzimidazole derivative which is an opioid designer drug. It was patented in 2024 as a potential novel analgesic, [1] but appeared on the illicit market at around the same time, first being identified in Germany in March 2024. [2] [3] It is a potent opioid agonist in vitro with similar potency to N-Desethyletonitazene. [4]
