Influences of renal function descriptors on population pharmacokinetic modeling of vancomycin in Chinese adult patients

Acta Pharmacologica Sinica · 10.1038/aps.2017.57

Structure

A one-compartment model, driven by creatinine clearance and age.

Study population

General patients — China and Asia. Fitted to 218 patients and 251 concentration observations.

Covariate As reported
Age 78 (42–95) yr
Weight 65 (38–90) kg
BMI 22.31 (12.85–36.89) kg/m²
CrCl 58.02 (5.45–224) mL/min
SCr 75 (24–893) mg/dL

Reported as the source publication gives them — mean ± SD, or median with range or interquartile range.

Equations

The model's structural parameters as Chorus implements them.

CL=2.829(1+0.00842(CrCl80))(75Age)0.8143CL = 2.829 \cdot (1 + 0.00842 \cdot (CrCl - 80)) \cdot \left(\frac{75}{Age}\right)^{0.8143}V1=52.14V_1 = 52.14

CL = 2.829 \cdot (1 + 0.00842 \cdot (CrCl - 80)) \cdot \left(\frac{75}{Age}\right)^{0.8143}
V_1 = 52.14

Implementation notes

Model for Chinese adults incorporating age and CrCl. Published age exponent typo (0.08143) corrected to 0.8143 based on Table 3.
