Balanced prior data

Abstract

The dataset used for this study contained the estimated pharmacokinetic (PK) data after intravenous tobramycin administration to children and adults with and without cystic fibrosis, which was previously analysed using a mixed effects modelling approach [1]. Hence, the following two compartment PK parameters: individual clearance (CL), central volume of distribution (V1), distributional clearance (Q) and peripheral volume of distribution (V2) estimates for each patient were available. For the purpose of this study, these individual PK parameter estimates were considered as data. From the whole dataset [1], only patients aged 1-25 years were included which resulted in data from 570 subjects (6.4 to 120 kg, 204 male patients) treated with tobramycin. Included in the Balanced prior data set are: ID (subejct identifier), AGE (age in years), WT (total body weight in kg), CL (clearance of tobramycin from the central compartment), V1 (volume of distribution of the central compartment), Q (intercompartmental clearance), and V2 (volume of distribution of the peripheral compartment).
