Outcome Measures

Primary Outcomes (12)

  • Number of Participants Who Experienced At Least One Adverse Event

    Up to 14 days after last dose of study drug

  • Number of Participants Who Discontinued Study Drug Due to an Adverse Event

    Up to 7 days after last dose of study drug

  • Area Under the Curve From 0 to 24 Hours (AUC 0-24hr) of Montelukast - Single Dose

    Blood samples for assessment of AUC 0-24hr were drawn predose and then at specified timepoints (up to 24 hours postdose) on Day 1 in Part I.

    Up to 24 hours postdose

  • AUC 0-24hr of Montelukast - Multiple Doses

    Blood samples for assessment of AUC 0-24hr were drawn predose and then at specified timepoints (up to 24 hours postdose) on Days 1 and 5 in Part II and on Days 1 and 10 in Part III.

    Up to 24 hours postdose

  • Maximum Plasma Concentration (Cmax) of Montelukast - Single Dose

    Blood samples for assessment of Cmax were drawn predose and then at specified timepoints (up to 24 hours postdose) on Day 1 in Part I.

    Up to 24 hours postdose

  • Cmax of Montelukast - Multiple Doses

    Blood samples for assessment of Cmax were drawn predose and then at specified timepoints (up to 24 hours postdose) on Days 1 and 5 in Part II and on Days 1 and 10 in Part III.

    Up to 24 hours postdose

  • Time to Cmax (Tmax) of Montelukast - Single Dose

    Blood samples for assessment of Tmax were drawn predose and then at specified timepoints (up to 24 hours postdose) on Day 1 in Part I.

    Up to 24 hours postdose

  • Tmax of Montelukast - Multiple Doses

    Blood samples for assessment of Tmax were drawn predose and then at specified timepoints (up to 24 hours postdose) on Days 1 and 5 in Part II and on Days 1 and 10 in Part III.

    Up to 24 hours postdose

  • Apparent Terminal Half Life (t1/2) of Montelukast - Single Dose

    Blood samples for assessment of t1/2 were drawn predose and then at specified timepoints (up to 24 hours postdose) on Day 1 in Part I.

    Up to 24 hours postdose

  • t1/2 of Montelukast - Multiple Doses

    Blood samples for assessment of t1/2 were drawn predose and then at specified timepoints (up to 24 hours postdose) on Days 1 and 5 in Part II and on Days 1 and 10 in Part III.

    Up to 24 hours postdose

  • AUC 0-24hr Accumulation Ratio of Montelukast - Multiple Doses

    The AUC 0-24hr Accumulation Ratio of Montelukast was calculated as the geometric mean ratio of AUC 0-24hr on the last day and the first day of a multiple dose regimen: Day 5/Day 1 in Part II and Day 10/Day 1 in Part III.

    up to 10 days after first dose of study drug

  • Cmax Accumulation Ratio of Montelukast - Multiple Doses

    The Cmax Accumulation Ratio of Montelukast was calculated as the geometric mean ratio of Cmax on the last day and the first day of a multiple dose regimen: Day 5/Day 1 in Part II and Day 10/Day 1 in Part III.

    up to 10 days after first dose of study drug
