Pharmacokinetic parameters

Parameter Definition
Cmax Maximum plasma concentration obtained directly from the data without interpolation.
Tmax Time to reach Cmax directly from the data without interpolation.
AUC0-last The area under the drug concentration-time curve, from time zero to time of the last measurable concentration, calculated by the “linear up and log down” method.
AUC0-inf Area under the drug concentration-time curve, from time zero extrapolated to infinity.
AUC0-12h Area under the drug concentration-time curve, from time 0 h to 12 h, calculated by the “linear up and log down” method.
AUC0-24h Area under the drug concentration-time curve, from time 0 h to 24 h, calculated by the “linear up and log down” method.
AUC%extrap The percentage of the AUC that was extrapolated beyond the last observed data point.
t1/2 Apparent plasma terminal elimination half-life.
λz or Kel The apparent terminal elimination rate constant.
CL/F Apparent total plasma clearance.
Vz/F Apparent terminal volume of distribution.

Kel, elimination rate constant. Values for λz, t1/2, AUC0-inf, AUC%extrap, CL/F, and Vz/F were not reported for cases that did not exhibit a terminal log-linear phase in the concentration versus time profile.
