Increased Metformin Clearance in Overweight and Obese Adolescents: A Pharmacokinetic Substudy of a Randomized Controlled Trial.


ABSTRACT: In view of the increased use of metformin in obese adolescents, the aim of this study was to determine the pharmacokinetics of metformin in overweight and obese adolescents.In overweight and obese adolescents receiving metformin 500 or 1000 mg twice daily for 37 weeks during a clinical trial, blood samples were collected over 8 h during an oral glucose tolerance test. Population pharmacokinetic modeling was performed using NONMEM.Data for 22 overweight and obese adolescents with a mean total body weight (TBW) of 79.3 kg (range 54.7-104.9), body mass index (BMI) of 29.1 kg/m2 (range 22.9-39.3), and age of 15.9 years (range 11.1-17.5) were analysed. In the model, oral clearance (CL/F) of metformin (1.17 l/min [relative standard error of 6%]) increased significantly with TBW (p?
