Etodesnitazene (Desnitroetonitazene, Etazen, Etazene, Etazone) is a benzimidazole derived opioid analgesic drug, which was originally developed in the late 1950s alongside etonitazene and a range of related derivatives.^[1] It is many times less potent than etonitazene itself, but still 70x more potent than morphine in animal studies. Corresponding analogues where the N,N-diethyl group is replaced by piperidine or pyrrolidine rings also retain significant activity (10x and 20x morphine respectively).^[2] Etodesnitazene has been sold as a designer drug,^[3] first being identified in both Poland and Finland in March 2020.^[4]^[5]
