The effect of disodium cromoglycate and Sch 1000 on exercise-induced asthma was studied in nine patients. The exercise stimulus consisted of either treadmill running or jogging; spirometric measurements were made before and at intervals after exercise. In six patients, disodium cromoglycate and Sch 1000 were both effective in preventing exercise-induced asthma. In two patients, Sch 1000 was effective, while disodium cromoglycate gave no protection. In the remaining patient, disodium cromoglycate was more effective than Sch 1000. The findings of this study suggest that the mechanism of exercise-induced asthma may be multifactorial, and the relative importance of each factor may vary in different patients.
