Isotonitazene

Isotonitazene is a benzimidazole derived opioid analgesic drug related to etonitazene, which has been sold as a designer drug. It has only around half the potency of etonitazene in animal studies, but this still makes it a similar strength to fentanyl and its analogues, and consequently isotonitazene can be expected to pose a significant risk of producing life-threatening respiratory depression, as well as other typical opioid side effects such as sedation, itching, nausea and vomiting.
