What researchers measure

Primary outcomes

  1. Area Under the Curve From Time Zero to Extrapolated Infinite Time [AUC (0-∞)]

    AUC (0-∞) = Area under the plasma concentration versus time curve (AUC) from time zero (pre-dose) to extrapolated infinite time (0-∞). It is obtained from AUC (0-t) plus AUC (t-∞).

    Time frame: 0, 1, 2, 3, 4, 6, 8, 10, 12, 14, 16, 24, 36, 48, 72, 96, 120 and 168 hours post dose

  2. Area Under the Curve From Time Zero to Last Quantifiable Concentration (AUClast)

    Area under the plasma concentration-time curve from time zero (pre-dose) to the time of the last measurable concentration (AUClast).

    Time frame: 0, 1, 2, 3, 4, 6, 8, 10, 12, 14, 16, 24, 36, 48, 72, 96, 120 and 168 hours post dose

  3. Maximum Observed Plasma Concentration (Cmax)

    Time frame: 0, 1, 2, 3, 4, 6, 8, 10, 12, 14, 16, 24, 36, 48, 72, 96, 120 and 168 hours post dose

Secondary outcomes

  1. Time to Reach Maximum Observed Plasma Concentration (Tmax)

    Time frame: 0, 1, 2, 3, 4, 6, 8, 10, 12, 14, 16, 24, 36, 48, 72, 96, 120 and 168 hours post dose

  2. Plasma Decay Half-life (t1/2)

    Plasma decay half-life is the time measured for the plasma concentration to decrease by one half.

    Time frame: 0, 1, 2, 3, 4, 6, 8, 10, 12, 14, 16, 24, 36, 48, 72, 96, 120 and 168 hours post dose
