Abstract

This study describes the population pharmacokinetics and dose personalization of cyclosporine in 36 patients with connective tissue diseases. A one-compartment open model with absorption was adopted as a pharmacokinetic model, and a nonlinear mixed effects model was used to analyze the population pharmacokinetic models. In the final model, age (AGE) and total body weight (TBW) were influential covariates on clearance (CL/F), which was expressed as CL/F (L/h)=17.8×(AGE/60)-0.269×(TBW/46.9)0.408, in addition to the volume of distribution (Vd/F), (L)=98.0 and absorption rate constant (Ka) (h-1)=0.67 (fixed). The results of the present study provide novel insights into factors involved in determining the most suitable dose and dosing strategy for individual patients with connective tissue disease.
