Primary outcomes

  1. Area Under the Curve From Time Zero to Extrapolated Infinite Time (AUC Infinity)

    Time frame: 0.25, 0.5, 1, 1.5, 2, 3, 4, 6, 9, 10, 12, 24, 36, 48, 72 hours post dose

    AUCinf = Area under the plasma concentration-time curve from time 0 (predose) extrapolated to infinite time; measured in nanograms times hour per milliliter (ng*hr/mL). Pharmacokinetic (PK) parameters derived from subject's concentration data; collected Period 1, Day 1 to Day 4; Period 2, Day 1 to Day 4.

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

    Time frame: 0.25, 0.5, 1, 1.5, 2, 3, 4, 6, 9, 10, 12, 24, 36, 48, 72 hours post dose

    AUClast = area under the plasma concentration-time curve from 0 (predose) to the time of the last measureable concentration (Clast). PK parameters derived from subject's concentration data; collected Period 1, Day 1 to Day 4; Period 2, Day 1 to Day 4.

  3. Maximum Observed Plasma Concentration (Cmax)

    Time frame: 0.25, 0.5, 1, 1.5, 2, 3, 4, 6, 9, 10, 12, 24, 36, 48, 72 hours post dose

    Cmax = maximum observed plasma concentration. Measured in nanograms per milliter (ng/mL); collected Period 1, Day 1 to Day 4; Period 2, Day 1 to Day 4.

Secondary outcomes

  1. Time to Reach Maximum Plasma Concentration (Tmax)

    Time frame: 0.25, 0.5, 1, 1.5, 2, 3, 4, 6, 9, 10, 12, 24, 36, 48, 72 hours post dose

    Tmax = time (hours) to maximum plasma concentration (Cmax). Observed directly from data as time of first occurrence; PK parameters derived from subject's concentration data; collected Period 1, Day 1 to Day 4; Period 2, Day 1 to Day 4.

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

    Time frame: 0.25, 0.5, 1, 1.5, 2, 3, 4, 6, 9, 10, 12, 24, 36, 48, 72 hours post dose

    t1/2 = terminal elimination half-life in hours; ln 2/kel, where kel is the termination phase rate constant calculated by a linear regression of the log-linear concentration-time curve. Only those data points judged to describe the terminal log-linear decline were used in the regression. PK parameters derived from subject's concentration data; collected Period 1, Day 1 to Day 4; Period 2, Day 1 to Day 4.
