Abstract

The aim of this double-blind placebo-controlled trial was to assess the efficacy and tolerance of nedocromil sodium at a dose of 4 mg four times daily, in the management of children suffering from grass-pollen asthma. Thirty-one children suffering from seasonal asthma (24 boys and seven girls, aged 4-21 yr, mean 11 yr) were enrolled in the study during the 1988 pollen season. Only one child was aged 4 yr, and she was a cooperative girl able to use the metered dose inhaler properly. In addition, in each group there was a patient aged 20 and 21 years, respectively, who had been followed up by us since childhood. Treatments were delivered by pressurized aerosol over a period of 4 weeks following a 1-week baseline, during which patients were required to show active disease by obtaining a minimum symptom score (almost 2 points of severity score on at least 3 days of the baseline period). The patients were randomly assigned to both treatment groups, all were taking inhaled or oral bronchodilators, when necessary. Twenty-nine patients completed the trial, 16 in the nedocromil sodium treatment group and 13 in the placebo group. One child of each group was withdrawn due to treatment failure. Statistically significant differences in favour of nedocromil sodium were found regarding morning tightness and mean morning PEFR values on diary cards (P
