Abbreviations: AUC0 − 48: area under the curve from 0 to 48 h; AUC0−∞: area under the curve from 0 to infinity; tmax: time to reach maximum concentration; Cmax: maximum concentration; t1/2: elimination half-life; MRT0−∞: mean residence time from time zero to infinity; CL/F: apparent total clearance of the drug; Vz/F: apparent volume of distribution during terminal phase after non-intravenous administration; V1: apparent volume, central or plasma compartment in a two-compartment model; V2: apparent volume, peripheral compartment in a two-compartment model; K12: rate constant, central to peripheral compartment; K21: rate constant, peripheral to central compartment.
