Abbreviations and definitions for pharmacokinetic parameters: Tmax,ss: the time to reach maximum (peak) concentration following drug administration at steady state; Cmax,ss: the maximum (peak) observed steady-state drug concentration in the plasma during multiple dosing; AUCτ: area under curve during a dosing interval (τ) at steady state; Cavg,ss: the mean observed steady-state drug concentration in the plasma during multiple dosing; Cmin,ss: minimum (trough) observed steady-state drug concentration in the plasma during multiple dosing; T1/2: elimination half-life associated with the terminal slope (λz) of a semilogarithmic concentration-time curve; Racc: accumulation ratio.
Median (min-max).
Geometric mean [%CV geo mean].
Arithmetic mean (SD).
Effective elimination half-life based on drug accumulation at steady-state (Boxenbaum and Battle, 1995).
