AUC indicates area under the plasma concentration–time curve; AUC0‐t, AUC from time of dose to last measurement; AUC0–∞, AUC from time of dose extrapolated to infinity; Cmax, peak plasma concentration; CV%, coefficient of variation; tmax, time from dose to Cmax; t½, half‐time of elimination.
Values are medians (minimum, maximum). Ranges in subscripts indicate time intervals of measurements.
