Detailed Description:

This was a randomized, open-label, active controlled, multicenter, parallel-group safety study in subjects 12 years of age and older with asthma. Subjects of appropriate age who completed the Phase III levalbuterol HFA MDI trials (Studies 051-353 or 051-355) were eligible to participate. Studies 051-353 and 051-355, both entitled "An Efficacy and Safety Study of Levalbuterol, Racemic Albuterol and Placebo in Subjects Twelve Years of Age and Older with Asthma" were multicenter, randomized, double-blind, placebo- and active-controlled, parallel-group studies of up to nine weeks in duration (a one-week single-blind placebo run in period followed by an eight-week double-blind treatment period). Subjects who completed Studies 051 353 and 051 355 but who were not immediately eligible to rollover into the current study could also participate but only after a 30-day washout. New subjects and subjects who participated in the Phase III trials who were not immediately eligible (ie, had a >30-day washout) were considered to be de novo subjects.

Study participation included 10 study visits over a 12 month period.
