title: Blood and tissue concentrations of tricyclic antidepressant drugs in post mortem cases: literature survey and a study of forty deaths.
abstract: Blood, urine, heart, liver, and psoas muscle concentrations of tricyclic antidepressant (TCA) drugs and their N-desmethyl metabolites were determined in forty medical examiner cases. The cases were evaluated for the role played by the TCA drugs in the cause of death and compared to a literature survey of previously reported cases. The incidence of the various individual TCA drugs as a factor and the significance of the disposition of the drugs and their metabolites is included. Comparing TCA drug concentrations in the heart and skeletal muscle and considering the differences in perfusion to these organs, TCA drugs and metabolites showed an affinity for the cardiac over the skeletal muscle. The case results were correlated with experimental studies to suggest the relationships of blood concentrations with toxicity.
