A Study of an Intravenous Drug in Pediatric Patients With Acute Asthma (0476-301)

A Multicenter, Randomized, Double-Blind Study Comparing the Clinical Effects of Intravenous Montelukast With Placebo in Pediatric Patients (Ages 6 to 14 Years) With Acute Asthma

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.

The duration of treatment is a one time dose.

Inclusion Criteria:

• Children 6-14 years of age seeking treatment in emergency departments with acute asthma attacks

Exclusion Criteria:

• Other respiratory conditions (including congenital lung abnormalities) or other acute illnesses that would complicate current treatment and response for asthma
