Structure

A two-compartment model, driven by weight and creatinine clearance.

Study population

General patients — Korea and Asia. Fitted to 220 patients and 1,020 concentration observations.

Covariate As reported
Age 63 (21–98) yr
Weight 61.6 (30–126.7) kg
CrCl 77 (4.57–279) mL/min
SCr 1.7 (0.2–13.3) 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 = 2.82 \cdot \left(\frac{CrCl}{72}\right)^{0.836}
V_1 = 31.8
V_2 = 75.4 \cdot \frac{Weight}{60}
Q = 11.7

Implementation notes

Korean general-population TDM model. HD and CRRT clearance covariates excluded; implemented for non-RRT patients.
