Action of nedocromil sodium in exercise-induced asthma in adolescents.

In view of the high incidence of exercise-induced asthma (EIA) in asthmatic adolescents and adults, the aim of the present study was to examine the preventive effect of nedocromil sodium administered prior to an exercise provocation test. The study involved 30 adolescents with EIA, aged between 14 and 19 years, who attended gymnastics classes at the Children's Hospital and Aerobics School. Baseline spirometry, six-minute treadmill running and spirometry for 7-15 minutes post-exercise were performed.
