Detection of the designer benzodiazepine metizolam in urine and preliminary data on its metabolism.
Designer benzodiazepines provide an attractive alternative to prescribed benzodiazepines for abuse purposes as they are readily available via the Internet without control. Metizolam was ordered via the Internet and a 2 mg blue tablet was orally administered to a 54-year-old man. Urine samples were collected over 6 days in polypropylene tubes. ⋯ Two authentic urine samples were analyzed using the same analytical method to search for metabolites of metizolam. M1, together with its glucuronide (M1-Glu), and M2 were observed in urine at the 8 h mark, whereas only M1 and M1-Glu were still detected in urine at 30 h post administration.
