Objective. To study pharmacokinetics (PK) and develop a pharmacokinetic/pharmacodynamic (PK/PD) model of linezolid for preterm infants, based on therapeutic drug monitoring (TDM) data.
Materials and Methods. The PK/PD analysis included data from therapeutic drug monitoring (TDM) of 24 premature infants, taking into account the repeated TDM procedure – a total of 27 occasions and 54 measurements of linezolid concentration. Quantitative determination of linezolid concentrations in the blood plasma of patients was carried out using the analytical method of measurement by HPLC-UV previously developed on the basis of the educational and scientific laboratory for the study of drug safety at the Department of General and Clinical Pharmacology of the RUDN University in the City Clinical Hospital No.
