Abstract
The possible antagonistic effect of the beta2-adrenoceptor agonist salbutamol and the methylxanthine theophylline on allergen-induced immediate skin reactions was elucidated. Dose-dependent reductions of early allergen-induced responses (flare and weal) were produced in eight atopic patients by salbutamol, 2.5 ng-1 μg (pppin vitro have similar counteracting effects on allergen-induced skin reactions in atopic subjects.
