The separation of seven structurally similar antidepressant drugs (amitriptyline, nortriptyline, imipramine, desipramine, protriptyline, doxepin, and nordoxepin) was achieved in under 15 min using a novel nonionic micelle polymer, poly(n-undecyl-alpha-D-glucopyranoside) (PUG) by use of capillary zone electrophoresis (CZE). Systematic studies with

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.
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

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

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
