✦ Synopsis

Chlorimipramine and other tricyclic antidepressant drugs are widely used for the treatment of depressive disorders. We analysed chlorimipramine and its major metabolite desmethylchlorimipramine after a two step extraction from plasma with diethylether. The underivatized samples were separated on a short (40 cm x 2 mm) silanized glass column packed with 3% OV 17 on Chromosorb HPW-DMCS, 80-100 mesh, which was directly coupled to the mass spectrometer. Detection of the tricyclic antidepressant drugs and their respective deuterium labelled internal standards was performed by chemical ionization using methanol vapour as reactant gas. The method is simple and sufficiently sensitive to permit the routine analysis of therapeutic plasma levels of tricyclic antidepressant drugs in extracts originating from 1 ml plasma.

## Abstract A highly sensitive and specific LC‐MS/MS method has been developed and validated for the estimation of torcetrapib (TTB) with 100 Β΅L hamster/dog plasma using DRL‐16126 as an internal standard (IS). The API‐4000 Q Trap LC‐MS/MS was operated under multiple‐reaction monitoring mode using t
