Nedocromil sodium in the prevention of exercise-induced bronchospasm in athletes with asthma.
The aim of this study was to determine the efficacy of nedocromil sodium in the prevention of exercise-induced bronchospasm (EIB) in 13 top athletes affected by bronchial asthma. At a dose of 4 mg the drug significantly reduced the fall in FEV1 compared with placebo but not with respect to basal values. In 9 athletes, 4 mg nedocromil sodium produced a good protective effect and reduced the mean fall in FEV1 to 4% with respect to baseline values, while in the remaining 4 subjects, the protective effect was not satisfactory. In these 4 "non responders" 6 mg nedocromil was effective, and in 2 cases induced prolonged bronchodilatation. In conclusion, the effect of nedocromil sodium in the prevention of EIB may be dose-dependent in relation to the degree of bronchial hyperreactivity or to interference of other factors.
