title: Effect of verapamil on allergen-induced asthma in patients with respiratory allergy.
abstract: Specific degranulation of mast cells and basophils depends upon transmembrane calcium flow. In the present studies the protective effect of the calcium-antagonist drug verapamil against allergen-induced asthma was assessed in eight atopic patients. The results of this study showed that verapamil, administered both orally or by aerosol, can prevent the specific bronchoconstriction.
