General description

Desmethyldoxpein is the primary urinary metabolite of doxepin, a tricyclic antidepressant used for the treatment of sleep maintenance and sold under trade names such as Silenor® and Aponal. This analytical reference standard is suited for use in LC/MS or GC/MS methods for urine drug testing, clinical toxicology, and forensic analysis applications.

Application

Desmethyldoxepin solution may be used as an internal standard in the high performance liquid chromatographic (HPLC) determination of bupivacaine in samples of human serum.

Doxepin--like other antidepressant drugs (ADs)--shows a variable antidepressant effect in clinical practice. The cause for this variability is as yet unclear; however, pharmacokinetic factors such as the variable permeability of doxepin into the cerebrospinal fluid (CSF), may contribute to the

Commercial preparations of the tricyclic anti-depressant doxepin contain 15% of the more active cis-doxepin and 85% of the trans-isomer. The single dose pharmacokinetics of doxepin and its major metabolite N-desmethyldoxepin were examined in 30 healthy young men. Results for total

Due to its tranquilizing properties, the tricyclic antidepressant doxepin may be misused as a doping agent in competition horses. Therefore, efficient analytical procedures are required to detect this drug in samples submitted for doping control. To screen for parent doxepin

Little information on the population pharmacokinetics of the tricyclic antidepressant doxepine and its pharmacologically active metabolite desmethyldoxepine is available. However, a more individualised drug therapy may be feasible if the influence of various patient characteristics on plasma concentration was known.
