title: Effect of nedocromil sodium on exercise-induced bronchoconstriction in children.
abstract: A double-blind, placebo-controlled, crossover study investigated the efficacy of nedocromil sodium in reducing bronchoconstriction subsequent to exercise challenge in asthmatic children. Twelve children aged 7-14 years (mean 10.8 years) were pretreated with nedocromil sodium aerosol (2 inhalations; 2 mg/inhalation) or matching placebo, 30 min prior to treadmill running. Lung function was measured at regular intervals postexercise and the mean maximum percentage decrease in PEF and FEV1 compared following nedocromil sodium or placebo pretreatment. Nedocromil sodium significantly reduced the fall in PEF (P less than 0.001) and FEV1 (P less than 0.001) and provided significantly greater protection (P less than 0.001) than placebo. No adverse reactions or unusual symptoms were observed.
