Median and range are provided for tmax.
AUC indicates area under the concentration-versus-time curve; Cl, systemic clearance; Cmax, peak concentration; CV, coefficient of variation; MRT, mean residence time; SD, standard deviation; t½, terminal phase elimination half-life; tmax, time to peak concentration; Vss, apparent steady-state volume of distribution.
