WebNov 25, 2013 · where R 0 is the rate of drug input. The C ss is proportional to the infusion rate directly. One additional trick you can use is the relationship between AUC for a dosing interval and AUC 0-∞ after a single dose: Based on this equality, if you calculate AUC 0-∞ after a single dose, you can then predict the steady state concentrations for ... Webto extrapolate to infinity. This can be calculated from the AUC(0-t) by the addition of a constant (Clast/λz), where Clast is the last observed quantifiable concentration and λz is the terminal phase rate constant. • AUC(0-tau): AUC to the end of the dosing period (for example for OD dosing, the dosing tau is 24hrs.)

WebInter-dose AUC (ie, most generally AUC 0–12 h) is more informative than C 0 because it correlates better with rejection in patients with kidney transplants [16–18]. However, AUC 0–12 h estimation based on a complete pharmacokinetic profile requires multiple blood samples over a 12-h period, which is uncomfortable for the patient and costly.

The VancoPK model was the most accurate and precise. It yielded a mean trough-only AUC of 491, with a correlation of 0.925. The RMSE was 41, meaning that approximately 95% of the trough-only AUCs were within 82 points of peak-trough AUCs (Table 4 and Figure 1). raw inlineWebDetails. If method is set to "trapezoid" then the curve is formed by connecting all points by a direct line (composite trapezoid rule). If "step" is chosen then a stepwise connection of two points is used..
