OTHER_PRE_SPECIFIED outcome
Timeframe: Pre-dose, 2, 4, 5, 6, 10, 14 and 24 hours following dosing in each period.Population: Since the PK sample collection only occurred until 24 hours and the approximate t1/2 at all doses appeared to be \>10 hours, t1/2 and area under the plasma concentration versus time curve until infinity (AUCinf) are not reported at any dose level.
Plasma decay half-life is the time measured for the plasma concentration to decrease by one half.

OTHER_PRE_SPECIFIED outcome
Timeframe: 14 and 24 hours following dosing in each period.Population: Since the PK sample collection only occurred until 24 hours and the approximate t1/2 at all doses appeared to be \>10 hours, t1/2 and area under the plasma concentration versus time curve until infinity (AUCinf) are not reported at any dose level.
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).
