Outcome Measures

Primary Outcomes (3)

  • Area under the curve (AUC): The AUC from administration to the last sampling time will be determined by the trapezoid method.

    0-168 h

  • Maximum Concentration (Cmax): The maximum plasmatic concentration (Cmax) will be obtained as the highest concentration observed in the sampling interval.

    0-168 h

  • Time maximum concentration (tmax) is observed. Will be reported as the time at which the maximum concentration is observed.

    0-168 h

Secondary Outcomes (1)

  • Constant of elimination (ke): Will be determined as the slope from the linear logarithmic regression of the terminal phase of the logarithmic graph of concentration over time.

    0-168 h
