title: Three-compartment open model analysis of micronomicin in man.
abstract: The pharmacokinetics of micronomicin (MCR) as a model drug of aminoglycoside antibiotics (AGs) was studied in man by applying our results previously obtained in rats. Three-compartment open model analysis of combined serum and total body store (T.B.S.) data obtained from multiple dosing in man was done using a non-linear least-squares regression program MULTI. We found large individual variations of MCR disposition in man and these variations did not appear within the serum concentration range measurable with conventional assay methods. This finding suggests that the disposition of AGs, included MCR, cannot be estimated by only plasma or serum level analyses. We conclude that the therapeutic drug monitoring of AGs by using T.B.S. data analysis should be an effective method for controlling therapy with AGs in the clinical setting.
