Description

General description

Zolpidem Phenyl-4-carboxylic acid is the major urinary metabolite of zolpidem, accounting for 51% of an administered dose. Literature references indicate the metabolite can be found in urine for 2-3 days following ingestion of a single therapeutic dose of zolpidem. Zolpidem, marketed as Ambien^® or Stilnox^®, is a nonbenzodiazepine used for the short-term treatment of insomnia.

Application

• Pharmacokinetics in forensic contexts: A study demonstrated the simultaneous analysis of Zolpidem and its metabolites, including Zolpidem phenyl-4-carboxylic acid, in postmortem urine, which is critical for forensic toxicology (Yamaguchi et al., 2023).



• Detection in hair samples: Research developed a sensitive LC-MS/MS method for detecting picogram levels of Zolpidem and its primary metabolites, such as Zolpidem phenyl-4-carboxylic acid, in hair, offering valuable insights for forensic and clinical investigations (Kim et al., 2021).



• Advanced analytical techniques: The determination of Zolpidem phenyl-4-carboxylic acid and Zolpidem 6-carboxylic acid in hair was achieved using gas chromatography-electron ionization-tandem mass spectrometry, enhancing the capabilities of toxicological analyses (Kwon et al., 2021).



• Pharmacokinetic profiling: A study on the pharmacokinetics of Zolpidem and Zolpidem phenyl-4-carboxylic acid in oral fluid post administration provided crucial data for understanding drug behavior in therapeutic monitoring (Feng et al., 2019).



• Forensic case study: An examination of a fatal zolpidem poisoning case highlighted the postmortem distribution and redistribution of Zolpidem and its predominant metabolite, Zolpidem phenyl-4-carboxylic acid, in body fluids and tissues, offering insights for forensic pathology (Hasegawa et al., 2018).
