ABSTRACT A metabonomic study on biochemical changes in the urine of type 2 diabetes mellitus (T2DM) patients after the treatment of sulfonylurea (SU) antidiabetic drugs was performed. An ultra‐performance liquid chromatography/mass spectrometry (UPLC/MS) method was used to generate metabolic fingerprints for the metabonomic analysis of urinary samples obtained from 20 T2DM patients without any drug treatment and 20 T2DM patients treated with SU antidiabetic drugs and 20 normal glucose tolerance subjects. The resulting data were subjected to chemometric analysis (principal component analysis and partial least squares discriminant analysis) to investigate the effect of SU antidiabetic drugs on urinary metabolite profiles of T2DM patients. Biomarkers such as xanthine, phenylalanine, tryptophan, hippurate, phenylacetylglutamine, carnitine C8:1, carnitine C10:3, uric acid and citrate were found to be responsible for the separation of T2DM and SU‐treated groups, which indicates a potential effect of SU on energy metabolism, Tricarboxylic acid (TCA) cycle, gut microflora metabolism and oxidative stress. The study may be helpful to the understanding of the action of mechanism of SU antidiabetic drugs. Copyright © 2014 John Wiley & Sons, Ltd.
