International Journal of Clinical Pharmacology and Therapeutics · 10.5414/CP201842

Structure

A one-compartment model, driven by creatinine clearance.

Study population

General patients — China. Fitted to 72 patients and 167 concentration observations.

Covariate As reported
Age 54.07 ± 18.36 yr
Weight 61.12 ± 10.7 kg
CrCl 32.09 ± 36.19 mL/min
SCr 0.9 ± 0.51 mg/dL

V_1 = 47.76

Implementation notes

One-compartment model for Chinese adults. CL is linearly related to CLcr below 80 mL/min and constant above 80 mL/min.
