Abstract

Protective effects of phentolamine, fenoterol, disodium cromoglycate and Ipratropiumbromid were studied against exercise induced bronchospasm in 20 patients with symptom-free bronchial asthma. Exercise testing was carried out on bycicle ergometer and body plethysmographic measurements were performed before and after the excertion. Each drug administered was found to inhibit significantly the bronchospasm provoked by exercise, but there were some differenes in the effects. Both the disturbance of alpha- and beta-receptor function and the cholinergic reflex mechanism are presumed to play a role in the phenomenon of 'exercise induced asthma'. Density dependence of gases by air and He-O2 mixture inhalation proved to decrease in the majority of the cases subsequent to the exercise testing, whilst it was found to increase in some patients, too. These results suggest that predominant site of airways obstruction in exercise induced bronchospasm can be localized to the large airways and the small ones, with remarkable individual differences.
