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.

A high-performance liquid chromatographic (HPLC) method was developed for the quantitative, simultaneous determination of the following four compounds in serum: E-doxepin, Z-doxepin, E-desmethyldoxepin, and Z-desmethyldoxepin. A 3-microns analytical silica column (6 x 100 mm) was employed with the mobile phase

It has been suggested that the polymorphism of the CYP2D6 gene can contribute to occurrence of fatal adverse effects. We therefore investigated postmortem toxicology cases of fatal drug poisonings related to CYP2D6 substrates, with the manner of death denoted as

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.
