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.

This study was conducted to identify the cytochrome P450s (CYPs) responsible for the metabolism of the cis- and trans-isomers of the tricyclic antidepressant doxepin to its pharmacologically active N-desmethylmetabolite by in vitro techniques. The doxepin N-demethylation was studied by means

European journal of clinical pharmacology, 58(4), 253-257 (2002-07-24)
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.

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
Antonia Gronewold et al.
Forensic science international, 190(1-3), 74-79 (2009-06-16)
Body fluids and tissues in eight doxepin (Dox)-related deaths were investigated in order to prove whether the individual concentration of Dox, the concentration sum of parent drug and its active metabolite N-desmethyldoxepin (NDox) or the concentration ratio Dox/Ndox valuably contribute
