Title: | Novel Benzodiazepines (Clonazolam and Flubromazolam) Identified in Candy-Like Pills. | Authors: | Weng Choy K.;Schneider H.G.;Drummer O.H.;Pope J.D. | Institution: | (Pope, Schneider) Clinical Biochemistry, Alfred Health ,Commercial Road, Melbourne, Australia (Pope, Drummer) Department of Forensic Medicine, Monash University, Melbourne, Australia (Weng Choy) Clinical Biochemistry, Monash Health, Melbourne, Australia (Schneider) Central Clinical School, Monash University, Melbourne, Australia | Issue Date: | 11-Mar-2021 | Copyright year: | 2018 | Publisher: | NLM (Medline) | Place of publication: | United Kingdom | Publication information: | The journal of applied laboratory medicine. 3 (1) (pp 48-55), 2018.

METHOD(S): Illicit PEZ-like pills purchased from an online vendor, containing unknown substances, were investigated by UHPLC-QTof. Accurate mass and experimental data were obtained. Tentative identifications were subsequently confirmed with commercial standards. RESULT(S): Accurate mass data, high-energy mass spectra, elucidation software, and a review of the scientific literature enabled the tentative identification of clonazolam and flubromazolam in the PEZ-like pills. On the basis of these tentative identifications, commercial standards were purchased to confirm the initial findings. On subsequent reinterrogation of the data, flubromazolam was identified in the urine specimen of the patient. CONCLUSION(S): Utilizing high-resolution mass data, 2 novel benzodiazepines were tentatively identified by reinterrogation of a routine analysis for drugs of abuse. Use of UHPLC-QTof in a clinical toxicology laboratory provides additional capabilities to explain and potentially improve treatment of patients presenting to the emergency department with symptoms possibly due to toxic substance ingestion.Copyright © 2018 American Association for Clinical Chemistry. | DOI: | http://monash.idm.oclc.org/login?url= http://monash.idm.oclc.org/login?url=http://dx.doi.org/10.1373/jalm.2017.025387 |
