Study Arms (2)

A

EXPERIMENTAL

Subjects will receive both treatments: (a) levalbuterol HFA MDI; 45 micrograms (8 cumulative doses); followed by (b) racemic albuterol HFA MDI; 90 micrograms (8 cumulative doses). The first treatment will be administered, followed by a 7 ±2 days washout period, after which the second of the two treatments will be administered. Cumulative dosing will occur according to the following schedule: 1 puff at 0 and 30 minutes, 2 puffs at 60 minutes, 4 puffs at 90 minutes and 8 puffs at 120 minutes. Treatment will be administered with an AeroChamber Plus ™ spacer for the first cohort (spacer cohort) of subjects and without the AeroChamber Plus ™ spacer (non-spacer cohort) for the second cohort of subjects.

Drug: Levalbuterol HFA MDI followed by Racemic albuterol HFA MDI

B

ACTIVE COMPARATOR

Subjects will receive both treatments: (a) racemic albuterol HFA MDI; 90 micrograms (16 cumulative doses) followed by (b) levalbuterol HFA MDI; 45 micrograms (16 cumulative doses) The first treatment will be administered, followed by a 7 ±2 days washout period, after which the second of the two treatments will be administered. Cumulative dosing will occur according to the following schedule: 1 puff at 0 and 30 minutes, 2 puffs at 60 minutes, 4 puffs at 90 minutes and 8 puffs at 120 minutes. Treatment will be administered with an AeroChamber Plus ™ spacer for the first cohort (spacer cohort) of subjects and without the AeroChamber Plus ™ spacer (non-spacer cohort) for the second cohort of subjects.

Drug: Racemic Albuterol followed by levalbuterol HFA MDI
