Outcome Measures
Primary Outcomes (2)
Area Under the Curve From Time Zero to Extrapolated Infinite Time [AUC (0 - 8)]
AUC (0 - 8)= Area under the plasma concentration versus time curve (AUC) from time zero (pre-dose) to extrapolated infinite time (0 - 8). It is obtained from AUC (0 - t) plus AUC (t - 8).

Secondary Outcomes (4)
