Filter by: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.
Intraoperative bronchospasm challenges anesthesia's safety. This study aims to investigate high concentration of exhaled nitric oxide as a marker of intraoperative bronchospasm.
It is our primary hypothesis that pretreatment with arformoterol will provide superior protection against EIB in children with mild-moderate asthma compared to placebo added to the current asthma regimen. Our secondary hypothesis is that nebulized arformoterol has comparable protection against EIB compared to inhaled formoterol by dry powder inhaler.
This clinical study will evaluate and establish the protective effects of Amphastar's Albuterol Sulfate HFA Inhalation Aerosol (Albuterol-HFA), in preventing exercise-induced bronchoconstriction (EIB) in adolescent and adult asthmatic patients, in comparison with (1) Proventil®-HFA (Reference drug and Active Control ), and (2) Placebo-HFA control (HFA propellant only). Safety of the test drug, Albuterol-HFA, will also be evaluated in comparison to the Active and Placebo Controls. Analyses will be performed to determine if the Armstrong's Albuterol-HFA has resulted in a significant bronchoprotective effect, with attenuated Max % Fall in FEV1, in comparison to the Placebo-HFA control.
GSK615915A is being developed as a novel surfactant for use in the formulation of GSK's future generation of Metered Dose Inhalers (MDIs). A surfactant in a MDI would provide a more stable drug suspension, this in turn will produce a consistent dose of drug being delivered with each puff.
The purpose of this study is to determine if treatment of exercise-induced Bronchospasm with montelukast will help college athletes train more effectively and thus become more competitive in a non ergogenic manner.
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.
During this study, your child will need to attend up to 5 office visits and maintain regular telephone contact with the clinic. Certain office visits will include physical exams, medical history review, exercise challenge test (walking/running on a treadmill), electrocardiogram (ECG) tests, and lung function tests. All study related medications and medical examinations are provided at no cost. All study drugs are currently available by prescription to patients 4 years and older.
