Description

General description

Doxepin is a tricyclic antidepressant used for the treatment of sleep maintenance. This internal standard is applicable for doxepin testing or isotope dilution methods by GC/MS or LC/MS for clinical toxicology, urine drug testing, or forensic analysis applications.

Application

• High-throughput protein precipitation method for doxepin analysis: A study presented a protein precipitation method using a 96-well plate to determine doxepin and nordoxepin levels in human plasma, employing LC-MS/MS, highlighting the utility of stable isotope-labeled doxepin for quantitative analysis in clinical settings (Margaryan et al., 2020).


• LC-MS-MS analysis of neuroleptics including doxepin: Research detailed the use of LC-MS-MS for analyzing neuroleptics like doxepin in hair samples from psychiatric patients, demonstrating the method′s effectiveness for long-term medication monitoring (Weinmann et al., 2002).


• Detection of doxepin in hair following therapy: A study investigated the detection of doxepin and its major metabolite in hair, providing a methodological foundation for forensic and clinical assessments of drug therapy adherence using hair samples (Negrusz et al., 1998).
