Summary

This trial tests whether montelukast, a drug used for asthma, can help infants hospitalized with acute bronchiolitis recover faster. About 60 children aged 4 weeks to 2 years will receive either montelukast or a placebo alongside standard care. Researchers will measure changes in symptom severity over 72 hours and how long each child stays in the hospital.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Montelukast, an oral drug that may reduce airway inflammation, given as a 4 mg sachet once daily at night.
What this could lead to
If effective, montelukast could become a standard add-on treatment to shorten hospital stays and speed recovery in infants with bronchiolitis.
What could go wrong
This is a small, early-stage trial, so results may not apply broadly. Montelukast may not improve symptoms or shorten stays, and side effects are possible.
