摘要: In order to compare long-term changes induced on a wide spectrum of bronchial hyperreactivity (BH) by the antiallergic drugs disodium cromoglycate (DSCG) and ketotifen, 56 asthmatic patients (age range 15-55 years) were studied. Patients allocated three groups with similar age BH level. During 2 months, 15 individuals inhaled 20 mg DSCG four times day, 14 took ketotifen 1 twice day orally one placebo (lactose) capsule day. After preliminary results, an additional group 13 clemastine for week. Only differed significantly from shifting log dose-response curves histamine. addition, no significant difference was seen between groups. These results suggest that mainly related its powerful antihistamine action; similarly, nonspecific is not wholly dependent mediator release.
