Pharmacokinetic assessments during the study will include area under the concentration-time curve from time zero (pre-dose) extrapolated to infinite time (AUC(0-infinity)), area under the concentration-time curve from time zero (pre-dose) to last time of quantifiable concentration within a subject across all treatments (AUC(0-t)), maximum observed concentration (Cmax), terminal phase half-life (t½), lag time before observation of drug concentrations in sampled matrix (tlag), time of occurrence of Cmax (tmax), concentration at 24 hours post-dose (C24), and apparent clearance following oral dosing (CL/F).
