Attenuation of early and late phase allergen-induced bronchoconstriction in asthmatic subjects by a 5-lipoxygenase activating protein antagonist, BAYx 1005.

BACKGROUND: The cysteinyl leukotrienes (LTC4, LTD4 and LTE4) have been implicated in the pathogenesis of allergen-induced airway responses. The effects of pretreatment with BAYx 1005, an inhibitor of leukotriene biosynthesis via antagonism of 5-lipoxygenase activating protein, on allergen-induced early and late asthmatic responses has been evaluated. METHODS: Eight atopic subjects with mild asthma participated in a two period, double blind, …
