Randomized Controlled Trial Multicenter Study Clinical Trial Controlled Clinical Trial
Montelukast, a leukotriene receptor antagonist, for the treatment of persistent asthma in children aged 2 to 5 years.
The greatest prevalence of asthma is in preschool children; however, the clinical utility of asthma therapy for this age group is limited by a narrow therapeutic index, long-term tolerability, and frequency and/or difficulty of administration. Inhaled corticosteroids and inhaled cromolyn are the most commonly prescribed controller therapies for young children with persistent asthma, although very young patients may have difficulty using inhalers, and dose delivery can be variable. Moreover, reduced compliance with inhaled therapy relative to orally administered therapy has been reported. One potential advantage of montelukast is the ease of administering a once-daily chewable tablet; additionally, no tachyphylaxis or change in the safety profile has been evidenced after up to 140 and 80 weeks of montelukast therapy in adults and pediatric patients aged 6 to 14 years, respectively. To our knowledge, this represents the first large, multicenter study to address the effects of a leukotriene receptor antagonist in children younger than 5 years of age with persistent asthma, as well as one of the few asthma studies that incorporated end points validated for use in preschool children. ⋯ Oral montelukast (4-mg chewable tablet) administered once daily is effective therapy for asthma in children aged 2 to 5 years and is generally well tolerated without clinically important adverse effects. Similarly, in adults and children aged 6 to 14 years, montelukast improves multiple parameters of asthma control. Thus, this study confirms and extends the benefit of montelukast to younger children with persistent asthma.

Randomized Controlled Trial Multicenter Study Clinical Trial
Early postnatal dexamethasone therapy for the prevention of chronic lung disease.
To test the hypothesis that early postnatal dexamethasone will reduce the incidence of death or chronic lung disease (CLD) in ventilated extremely low birth weight premature infants. ⋯ A 12-day course of early postnatal steroid therapy given to extremely low birth weight infants did not decrease the risk of CLD or death at 36 weeks postmenstrual age and was associated with an increased risk of complications and poor weight gain.
