ABSTRACT
AIM: To establish a population pharmacokinetics (PPK) model of vancomycin in patients with hematological diseases who developed neutropenia. METHODS: Patients from department of hematology with neutropenia in our hospital were taken into oue study.The patients (n=77) were performed trough and peak serum concentration of vancomycin, and their clinical data and medication information were collected. The Nonlinear mixed effect modeling approach (NONMEM) was used to establish the PPK model of those patients and model assessment and validation was carried out. Goodneess of fit plots and visual predictive check plus Bootstrap approach were used to assess validate our model. RESULTS: The model was a two compartment model, the final formulas were: clearance rate CL=6.84×(BW/70)
