Interpreting mono- and poly-SCRA intoxications from an activity-based point of view: JWH-018 equivalents in serum as a comparative measure.

Synthetic cannabinoid receptor agonists (SCRAs) are a class of synthetic drugs that mimic and greatly surpass the effect of recreational cannabis. Acute SCRA intoxications are in general difficult to assess due to the large number of compounds involved, differing widely in both chemical structure and pharmacological properties. The rapid pace of emergence of unknown SCRAs hampers on one hand the timely availability of methods for identification and quantification to confirm and estimate the extent of the SCRA intoxication.

A case of fatal multidrug intoxication involving flualprazolam: distribution in body fluids and solid tissues.

Purpose: Designer benzodiazepines (DBZDs) increasingly emerged on the novel psychoactive substance (NPS) market in the last few years. They are usually sold as readily available alternatives to prescription benzodiazepines (BZDs) or added to counterfeit medicines. BZDs are generally considered relatively safe drugs due to the low risk of serious acute adverse effects in mono-intoxication, though e.

Effect of new legislation in Germany on prevalence and harm of synthetic cannabinoids.

Context: New psychoactive substances (NPS) have become an ongoing threat to public health. To prevent the emergence and spread of NPS, a new German law, the 'NpSG' took effect in November 2016. This study presents an overview of analytically confirmed synthetic cannabinoid (SC) intoxications from January 2015 to December 2018.

Hemoadsorption eliminates remdesivir from the circulation: Implications for the treatment of COVID-19.

Both antiviral treatment with remdesivir and hemoadsorption using a CytoSorb adsorption device are applied in the treatment of severe COVID-19. The CytoSorb adsorber consists of porous polymer beads that adsorb a broad range of molecules, including cytokines but also several therapeutic drugs. In this study, we evaluated whether remdesivir and its main active metabolite GS-441524 would be adsorbed by CytoSorb .

Use of the CytoSorb adsorption device in MDMA intoxication: a first-in-man application and in vitro study.

Background: 3,4-Methylenedioxymethamphetamine (MDMA, "ecstasy") abuse is frequent, and overdosing might cause severe and eventually lethal multi-organ failure. To date, there is no causal therapy of MDMA intoxication and removal of MDMA from the circulation might be a reasonable measure to prevent adverse courses after overdosing. We present here first-in-man experience and in vitro data supporting a potential role of an adsorber device in severe MDMA overdosing.

Acute severe intoxication with cyclopropylfentanyl, a novel synthetic opioid.

Background: Since 2016 an increase has been observed in the availability of new synthetic opioids (NSO) in Europe. Cyclopropylfentanyl is a very potent and selective μ-opioid agonist, which was reported for the first time in August 2017 in Europe.

Methods: The case was included in a prospective observational study of patients treated in emergency departments after the intake of novel psychoactive substances (NPS).
