Outcome Measures

Primary Outcomes (5)

  • Area under the plasma concentration vs time curve from time zero extrapolated to infinity

    a pharmacokinetic measure of the amount of study medication present in the blood

    24 hours

  • AUC from time zero to time of last quantifiable analyte concentration

    a pharmacokinetic measure of the amount of study medication present in the blood

    96 hours

  • Half-life associated with terminal slope of a semi-logarithmic concentration-time curve

    a pharmacokinetic measure of the time it takes for the study drug to be eliminated from the blood

    24 hours

  • Total body clearance following iv administration

    a pharmacokinetic measure of the time it takes for the study drug to be eliminated from the blood

    24 hours

  • Volume of distribution following iv administration

    a theoretical estimate of how much of the study drug that the body may contain

    24 hours

Secondary Outcomes (4)
