The thromboxane (TX) synthetase inhibitor, ozagrel hydrochloride, inhibits acetaldehyde-induced bronchoconstriction in asthmatic patients. The present study evaluated the involvement of TXA(2) on alcoholic beverage-induced bronchoconstriction. Four patients with alcohol-induced asthma received ozagrel (400 mg for 4 days) or placebo using a single-blind, randomized, cross-over design. On two separate study days, each subject drank the same brand and volume of alcoholic beverage (beer or Japanese sake) and bronchoconstriction was assessed as the change in peak expiratory flow (PEF). The effect of ozagrel on the aerosolized challenge of acetaldehyde was investigated in the same subjects. Although aerosolized acetaldehyde-induced bronchoconstriction was significantly prevented by ozagrel, there were no differences in the time course of the decrease in PEF or the maximum fall in PEF after alcohol intake between placebo and ozagrel. We conclude that TXA(2) is not involved in alcoholic beverage-induced bronchoconstriction.
