Optimization of therapeutic drug monitoring of vancomycin in newborns using “Dried Blood Spot” method by V. I. Petrov, I. S. Anikeev, T. E. Zayachnikova, A. V. Strygin, D. V. Kurkin, Yu. S. Kazmina

“…Therapeutic drug monitoring (TDM) is used to increase the individualization of pharmacotherapy, especially in patient groups with a high interindividual variability in pharmacokinetic (PK) parameters. One of these groups of patients is newborn children, for whom drug therapy, especially drugs with a narrow therapeutic range, causes a few difficulties or cannot be used in principle.The aim of the work was to develop and validate quantitative HPLC-MS/MS methods for the determination of vancomycin in “dried blood spot” samples using new protocols and comparison of the results obtained with the results in plasma samples using standard sample preparation methods.Materials and methods. …”
