General description

Oxazepam glucuronide is a major urinary metabolite of the benzodiazepine drug, oxazepam. Oxazepam, marketed as Alepam, Medopam, or Murelax®, has been used extensively since the 1960s for treatment of anxiety and insomnia and in the control of symptoms of alcohol withdrawal. This certified reference solution is suitable for GC/MS or LC/MS applications with oxazepam or oxazepam glucuronide such as urine drug testing, pain prescription monitoring, toxicology analysis, or forensic testing.

Application


  • Advanced Analytical Techniques for Benzodiazepine Metabolites: Oxazepam glucuronide has been targeted in studies using high-performance liquid chromatography with tandem mass spectrometry (HPLC-MS/MS). This method allows for the sensitive and automatic determination of diazepam and its metabolites, including oxazepam glucuronide, in human oral fluid, highlighting its utility in forensic and clinical toxicology (Jiang et al., 2016).

  • Forensic Applications: Oxazepam glucuronide is directly determined using μElution solid-phase extraction and liquid chromatography-tandem mass spectrometry (LC-MS/MS) in human whole blood. This technique is crucial for forensic science, providing reliable data for legal and medical investigations involving benzodiazepine use (Wang et al., 2013).

The disposition of tracer doses of 3H-oxazepam was studied in the recirculating perfused mouse liver preparation. 3H-Oxazepam was biotransformed primarily to the diastereomeric 3H-oxazepam glucuronides, which either effluxed into the circulation or underwent biliary excretion. Three additional, unknown metabolites constituted

Six healthy volunteers received oxazepam 15 mg i.v. and orally at an interval of at least one week. The kinetic variables of i.v. oxazepam were: elimination half-life (t1/2 beta) 6.7 h, total clearance (CL) 1.07 ml.min-1.kg-1, volume of distribution (Vc)

British journal of clinical pharmacology, 20(3), 225-234 (1985-09-01)
Single dose pharmacokinetics of oxazepam, 30 mg, have been studied in six healthy male volunteers in the absence of diflunisal and during continuous treatment with diflunisal 500 mg twice daily. During diflunisal treatment, peak plasma concentration of oxazepam significantly decreased

The concentrations of (R)-(-)- and (S)-(+)-oxazepam glucuronides in plasma and urine of several species have been measured. The relative amounts of these diastereoisomers vary among species. Thus, in the plasma and urine of rhesus monkeys the concentrations of the R-isomer

Protocols

Using UHPLC/MS (TOF) for Detection of Drugs and Metabolites in Urine Following Optimized Enzymatic Hydrolysis Conditions

To optimize hydrolysis using β-glucuronidase, factors such as incubation time, temperature, hydrolysis pH, enzyme source, and enzyme concentration must be evaluated for each glucuronide metabolite to be analyzed.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
