Background Isotonitazene is a novel opioid that was first reported in Europe in 2019. There have been no reports of the detection of isotonitazene in patients presenting to the emergency department with acute drug toxicity. Aim There was an increase in presentations to our emergency department with acute opioid toxicity in August 2021. We aim to describe this outbreak and provide detail on two cases in which isotonitazene was quantified in serum samples. Methods Serum samples were available for comprehensive toxicological analysis for two presentations. Written consent was obtained and the samples were analysed through a Thermo XRS ultrahigh-performance liquid chromatography system, interfaced to a Thermo Q Exactive high-resolution accurate mass spectrometer, operating in heated positive ion electrospray mode. Acquired data were processed using Toxfinder software (Thermo) against a regularly updated in-house database. Results There was an increase in acute opioid presentations to our emergency department from a median of 10 per month to 36 in August 2021. Twenty were treated with naloxone, and 23 were admitted to the hospital for observation and treatment. Serum sample analysis from two patients with acute opioid toxicity responsive to naloxone detected the presence of isotonitazene (0.18 and 0.81 ng/ml). Conclusion We report a cluster of acute opioid toxicity presentations to our Emergency Department with detection of isotonitazene in two cases. Analytical screening is important in determining the presence of novel psychoactive substances (NPS) and to help inform the public health of the implications of NPS use, particularly during clusters of acute recreational drug toxicity presentations.
