Data are presented as n, mean±sd or median (range). Pharmacokinetic parameters were estimated using noncompartment analyses. Cmax: maximum observed concentration; tmax: time of maximum observed concentration; AUC0-t: area under the concentration–time curve from dose administration at time 0 to tlast, where tlast is the time of last measurable observed concentration; MRT: mean residence time; t½: half-life; NR: not reportable; NC: not calculated. #: n=3; : n=2; +: n=1.
