Detailed Description

This is a single blind (investigator unblinded), open label, single exposure, non-randomized, single center, outpatient, stepwise, rising dose study in male subjects with mild intermittent asthma to assess topical safety and tolerability of Albuterol Sulfate Acu-30™ DPI, compared with Placebo Acu-30™ DPI. Increasing doses of each drug will be administered in a sequential fashion in 4 steps to 3 different subjects at each step (a total of 12 subjects) with mild intermittent asthma in each step.
