Pharmacokinetic Parameters Derived

Parameter Description
Cmax Maximum observed drug concentration
tmax Time to reach Cmax
AUC0-t Area under the drug concentration time curve from time 0 to time t, where t is the time of the last measurable concentration [Cp], calculated using the linear trapezoidal rule
AUC0-∞ Area under the drug concentration time curve from time 0 to infinity, calculated as AUC0-∞ = AUC0-t + CpZ
AUC0-15 min Area under the drug concentration time curve from time 0 to 15 minutes
AUC0-30 min Area under the drug concentration time curve from time 0 to 30 minutes
t Terminal elimination half-life, calculated as ln(2)/λZ where λZ is the apparent first-order terminal elimination rate constant calculated from a semi-log plot of the concentration vs time curve by linear least-squares regression analysis
λZ Terminal elimination rate constant
AUC%extrap Percentage of AUC0-∞ extrapolated from Cp to infinity, calculated as 100 × (1 − [AUC0-t/ AUC0-∞])

AUC = area under the curve.
