Asthma
Conditions
Brief summary
This study will attempt to find out if the addition of an intravenous form of a drug that is already used for treating asthma in children will help resolve asthma attacks faster than using the current standard care alone.
Detailed description
The duration of treatment is a one time dose.

Pbo for a study approximately 120 minutes in duration
