Primary Outcome Measures:
  • Maximum drug concentration (Cmax) [ Time Frame: Multiple sampling from 0 to 36 hours following single dose ] [ Designated as safety issue: No ]
  • Area under the plasma drug concentration versus time curve from hour 0 to the time with a last quantifiable level (AUCo-t) [ Time Frame: Multiple sampling from 0 to 36 hours (could be less than 36 hours if the last quantifiable concentration is below limit of quantification), following single dose ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Time to reach maximum plasma concentration (tmax) [ Time Frame: Multiple sampling from 0 to 36 hours following single dose ] [ Designated as safety issue: No ]
  • Plasma concentration at the end of infusion (C15' ) [ Time Frame: At 15 minutes after termination of the15-minutes infusion ] [ Designated as safety issue: No ]
  • Area under the curve from 0 to infinity (AUC) [ Time Frame: Multiple sampling from 0 to 36 hours following single dose ] [ Designated as safety issue: No ]
  • Mean resident time (MRT) [ Time Frame: Multiple sampling from 0 to 36 hours following single dose ] [ Designated as safety issue: No ]
  • Terminal elimination half-life(t1/2) [ Time Frame: Multiple sampling from 0 to 36 hours following single dose ] [ Designated as safety issue: No ]
  • First order terminal elimination rate constant (λz ) [ Time Frame: Multiple sampling from 0 to 36 hours following single dose ] [ Designated as safety issue: No ]
  • Total body clearance after oral administration (CL/F) or after IV infusion (CL) [ Time Frame: Multiple sampling from 0 to 36 hours following single dose ] [ Designated as safety issue: No ]
  • Volume of distribution after oral administration(Vz/F) or after IV infusion(Vz) [ Time Frame: Multiple sampling from 0 to 36 hours following single dose ] [ Designated as safety issue: No ]
