The aim of the study was to determine whether zileuton, an inhibitor of 5-lipoxygenase, attenuated bronchial hyperresponsiveness (BHR) in asthmatic subjects who had marked BHR during maintenance treatment with inhaled corticosteroids (ICS). In a randomized, double-blind, placebo-controlled, cross-over study, a challenge test with histamine (provocative concentration of histamine producing a 20% fall in forced expiratory volume in one second (FEV1) (PC20,Hist)) and with ultrasonically nebulized distilled water (UNDW) (provocative dose of UNDW producing a 20% fall in FEV1 (PD20,UNDW)) was performed in seven patients with asthma after intake of either 400 mg zileuton or placebo. All patients (mean age 33 yrs, mean FEV1 111% of predicted) had marked BHR, as indicated by a mean PD20,UNDW of 4.74 mL under treatment for at least 6 months with up to 800 microg ICS (mean 536 microg daily). On four different occasions, separated by at least 5 days, two UNDW and two histamine challenge tests were performed in random order 3 h after a morning dose of either zileuton or placebo. Neither zileuton nor placebo changed baseline airway calibre prior to provocation. Zileuton increased PC20,Hist from 0.99 to 5.64 mg x mL(-1) (2.1 doubling doses; p<0.03 compared to placebo), and increased PD20,UNDW from 3.10 to 9.31 mL (1.3 doubling doses; p<0.05 compared to placebo). In conclusion, a single dose of 400 mg zileuton attenuates bronchial hyperresponsiveness to histamine and ultrasonically nebulized distilled water in asthmatic patients with marked bronchial hyperresponsiveness during treatment with inhaled corticosteroids.
