British Journal of Clinical Pharmacology · 10.1111/j.1365-2125.2005.02547.x

Structure

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

Study population

General, Critically ill and Mixed patients — Scotland, United Kingdom and Europe. Fitted to 139 patients and 559 concentration observations.

Covariate As reported
Age 66 (17–87) yr
Weight 72.5 (44–112) kg
CrCl 60 (12–172) mL/min
SCr 1.14 (0.51–5.96) 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=2.97(1+0.0205(CrCl57))CL = 2.97 \cdot (1 + 0.0205 \cdot (CrCl - 57))V1=1.24WeightV_1 = 1.24 \cdot Weight
LaTeX source
CL = 2.97 \cdot (1 + 0.0205 \cdot (CrCl - 57))
V_1 = 1.24 \cdot Weight

Implementation notes

One-compartment model developed for cardiothoracic surgery patients with unstable renal function.
