Filter by:This is a multicenter, randomized, double-blind, single-dose, placebo-controlled, 2-period, crossover study to evaluate the efficacy and safety of budesonide/albuterol metered-dose inhaler (BDA MDI/PT027) as compared with a placebo metered-dose inhaler (placebo MDI) on exercise-induced bronchoconstriction (EIB) in adult and adolescent subjects with asthma. Subjects will receive each study treatment on separate visits and undergo a treadmill exercise challenge test for up to 10 minutes so that the effect of study treatment on exercise-induced bronchoconstriction can be evaluated.
The term exercise-induced bronchospasm (EIB) describes acute, transient airway narrowing that occurs during, and most often after, exercise. Manifestations of EIB can range from mild impairment of performance to severe bronchospasm and respiratory failure. The pathogenesis of EIB remains controversial and the role of airway inflammation has not yet been definitively characterized. We plan on comparing markers of inflammation in asthmatic participants with and without EIB at baseline and after bronchoprovocation with eucapnic voluntary hyperventilation testing (EVH). We also will collect demographic information as well as information about asthma control and exercise habits.
The purpose of the study is to test how well 2 different medications stop asthma symptoms caused by exercising. The two medications that will be tested are "pretreatment with albuterol" and montelukast (Singulair®). Although both medications are used for treating asthma, we don't know which medicine is better at stopping asthma symptoms caused by exercising.
To determine if administration of levalbuterol tartrate HFA MDI in subjects with EIB will be effective in the prevention of EIB and be safe and well-tolerated.
This study was designed to examine the effectiveness of two bronchodilator inhalers in patients who have exercise-induced asthma.
