title: A SepPak HPLC method for tricyclic antidepressant drugs in human vitreous humor.
abstract: Death from tricyclic antidepressant overdose has become an all-too-common occurrence. Several factors, including postmortem concentration changes, can render blood and tissue samples useless for the determination of antidepressant drug concentrations. We present here an efficient method of solid-phase extraction for these drugs from vitreous humor and a reversed-phase, isocratic high-performance liquid chromatographic method for the simultaneous quantitation of amitriptyline, doxepin, and imipramine and their desmethylated metabolites.
