Outcome Measures

Primary Outcomes (1)

  • Total Airway Resistance Increase

    concentration of methacholine required to increase total airway resistance by 40% (PC40R5)

    1 to 7 days

Study Arms (2)

Advair Diskus100/50 µg and Advair Diskus 100/50 µg

ACTIVE COMPARATOR

The Advair Diskus 100/50 µg and Advair Diskus 100/50 µg will be administered in a blinded fashion. One hour after receiving the dose of Advair a methacholine challenge will be performed to determine the PC40R5. After the PC40R5 has been reached or a negative result after the highest methacholine concentration, 64 mg/mL, subjects will inhale albuterol through a valved holding chamber to reverse bronchoconstriction and their lung function will be monitored until it has returned to within 20% of that day's baseline R5.

Drug: Advair Diskus100/50 µgDrug: Methacholine ChlorideDrug: Albuterol

Advair Diskus 100/50 µg and Flovent Diskus 100 µg

ACTIVE COMPARATOR

The Advair Diskus 100/50 µg and Flovent Diskus 100 µg will be administered in a blinded fashion. One hour after receiving the dose of Advair and Flovent a methacholine challenge will be performed to determine the PC40R5. After the PC40R5 has been reached or a negative result after the highest methacholine concentration, 64 mg/mL, subjects will inhale albuterol through a valved holding chamber to reverse bronchoconstriction and their lung function will be monitored until it has returned to within 20% of that day's baseline R5.
