Abstract

A method for calculating the mean residence times of metabolites in the body, systemic circulation, and peripheral tissue is described. The calculations require the AUC, AUMC, and derivatives of the plasma concentration versus time curves of the metabolite and its precursor. The method is applicable to metabolites with any precursor order and does not require separate administration of the metabolite. The approach is applied to published data for the primary and secondary metabolites of ketamine.
