Abstract

We wanted to evaluate the effect of terfenadine, a selective H1-receptor antagonist, on alcoholic beverage-induced bronchoconstriction. Eight patients with alcohol-induced asthma received terfenadine (60 mg, twice on the test day) or placebo, with the last dosing 2 h before the test in a double-blind, randomized, cross-over manner. On two separate study days, each subject drank the same brand and volume of alcoholic beverage (beer or Japanese saké), and bronchoconstriction was assessed as change in peak expiratory flow (PEF) over 120 min postchallenge. Inhalation challenges were performed with the same alcoholic beverage with which they had been orally challenged. The mean (SEM) percentage fall in PEF 15, 30, 45, 60, 90 and 120 min after the oral alcohol challenge was significantly reduced from 12.0 (3.1), 17.0 (1.7), 15.8 (2.3), 15.2 (3.4), 16.6 (4.8) and 14.7 (5.2)%, to 2.6 (1.8), 2.1 (1.6), 3.9 (1.2), 5.7 (2.2), 6.5 (2.6), 5.1 (1.6)%, respectively, by terfenadine. No significant bronchoconstriction was observed after the inhalation challenge. We conclude that the release of histamine makes a major contribution to alcoholic beverage-induced bronchoconstriction in Japanese asthmatic patients, and that histamine H1 antagonists ...Continue Reading

Allergy and Asthma

Allergy and asthma are inflammatory disorders that are triggered by the activation of an allergen-specific regulatory t cell. These t cells become activated when allergens are recognized by allergen-presenting cells. Here is the latest research on allergy and asthma.
