Airway Responses to Montelukast and Desloratadine.

January 18, 2008 updated by: University of Saskatchewan
Montelukast (for asthma) and desloratadine (for allergies) are effective therapy for their current uses. Part of what happens when your allergies trigger your asthma should be prevented by either of these drugs. This project is being conducted to determine if these drugs are effective, either alone or in combination, on controlling asthma that is triggered by allergies.
