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

Doxepin is a tricyclic antidepressant marketed as an irrational mixture of cis- and trans-geometric isomers in the ratio of 15:85. A convenient high-performance liquid chromatographic (HPLC) procedure for simultaneous quantitation of geometric isomers of doxepin and N-desmethyldoxepin in plasma and
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

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.

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
