  • Maximum concentration pharmacokinetic endpoint for tigecycline [ Time Frame: -1, 0, 0.5, 1, 2, 3, 4, 8, 12, 16, 24, 48, 72, 96 hours ]
  • Time of maximum concentration pharmacokinetic endpoint for tigecycline [ Time Frame: -1, 0, 0.5, 1, 2, 3, 4, 8, 12, 16, 24, 48, 72, 96 hours ]
  • Elimination rate constant pharmacokinetic endpoint for tigecycline [ Time Frame: -1, 0, 0.5, 1, 2, 3, 4, 8, 12, 16, 24, 48, 72, 96 hours ]
  • Half life pharmacokinetic endpoint for tigecycline [ Time Frame: -1, 0, 0.5, 1, 2, 3, 4, 8, 12, 16, 24, 48, 72, 96 hours ]
  • Area under the concentration time curve to last measured concentrations pharmacokinetic endpoint for tigecycline [ Time Frame: -1, 0, 0.5, 1, 2, 3, 4, 8, 12, 16, 24, 48, 72, 96 hours ]
  • Area under the concentration time curve extrapolated to infinity pharmacokinetic endpoint for tigecycline [ Time Frame: -1, 0, 0.5, 1, 2, 3, 4, 8, 12, 16, 24, 48, 72, 96 hours ]
  • Clearance pharmacokinetic endpoint for tigecycline [ Time Frame: -1, 0, 0.5, 1, 2, 3, 4, 8, 12, 16, 24, 48, 72, 96 hours ]
  • Volume of distribution at steady-state pharmacokinetic endpoint for tigecycline [ Time Frame: -1, 0, 0.5, 1, 2, 3, 4, 8, 12, 16, 24, 48, 72, 96 hours ]
  • Response-exposure relationships between QT/QTc and tigecycline concentration [ Time Frame: -1, 0, 0.5, 1, 2, 3, 4, 8, 12, 16, 24, 48, 72, 96 hours ]
