Summary

This study looked at 101 children aged 6 to 17 with moderate to severe asthma attacks in the emergency room. It compared two medications, racemic albuterol and levalbuterol, to see which one improved breathing better and reduced the need for hospital admission. The goal was to find the most effective treatment for acute asthma flare-ups.
