  • Title: Oxatomide and exercise-induced asthma in children: the value of serial exercise tests.
    Author: Silverman M, Tooley M.
    Journal: Clin Allergy; 1981 Sep; 11(5):421-8. PubMed ID: 6119168.
    Abstract:
    Two groups of eight asthmatic children carried out serial treadmill exercise tests at 2-hourly intervals, after double-blind premedication with oxatomide (2 mg/kg by mouth), sodium cromoglycate powder (20 mg by inhalation) or matched placebo preparations. The drugs were studied in one group up to 6 hr and in the other group (omitting sodium cromoglycate) from 4 to 10 hr after administration. Peak expiratory flow rate was measured before and after exercise to give an index of exercise-induced asthma. Oxatomide had a slight but significant bronchodilator effect. After a lag period of up to 4 hours, oxatomide exerted a significant protective effect against exercise-induced asthma which lasted until at least 8 hr. At 10 hr after ingestion, the effect had gone. A mean maximum diminution of exercise-induced asthma of 49% was found, in comparison with placebo. Oral oxatomide after a lag period, exerts a significant protective effect against exercise-induced asthma. The relevance of these observations for the clinical management of asthma remains to be determined.
