What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Sensitivity analysis

    Sensitivity analysis is percentage of asthmatics subjects with positive final challenge compared with total asthmatics subjects in this study.

    Measured: On the 1 day of administration

  2. Specificity Analysis

    Specificity is the percentage of healthy subjects with negative results in healthy subjects in this study.

    Measured: On the 1 day of administration

  3. Provocative dose causing a 20% fall (PD20)

    PD20 is provocative dose causing a 20% fall in forced expiratory volume in 1 second (FEV1) .

    Measured: On the 1 day of administration

  4. Adverse events

    adverse events occured after administration

    Measured: Base line to 3 days after dosing

  5. heart rate (Vital signs)

    Measured: Base line to 3 days after dosing

  6. oxyhemoglobin saturation (Vital signs)

    Measured: Base line to 3 days after dosing

  7. Recovery of forced expiratory volume in 1 second (FEV 1)

    Recovery of forced expiratory volume in 1 second (FEV 1) after administration to assess safty profile.

    Measured: Base line to 3 days after dosing
