    Abstract

    Objective: Leukotriene antagonists are increasingly used in asthma management. Pranlukast is a new, orally active, selective inhibitor of CysLt1 leukotriene receptor. The present clinical trial was performed to study the effect and safety of pranlukast in mild-to-moderate asthma. Methodology: A randomized, double-blind, placebo-controlled, parallel group study was performed in eight medical centres in Korea. Mild-to-moderate asthma patients who had been treated with β2-agonists and/or inhaled corticosteroids were studied. The patients' symptoms were evaluated by asthma diary and twice-daily peak flow monitoring. Results: Of the 206 patients enrolled, 197 were eligible for analysis. The pranlukast group (n=98) showed statistically significant improvement in asthma symptoms, including asthma attack rate, daily living score, and morning and evening asthma scores. Pranlukast significantly reduced the consumption of β2-agonist. Compared with the placebo group, forced vital capacity (FVC) and forced expiratory volume in 1 s (FEV1) were not significantly higher in the pranlukast group. Morning and evening peak expiratory flow (PEF) were significantly increased after pranlukast treatment at weeks 2 and 4 (380.8 ± 10.1 L/min at baseline, 394.5 ± 10.1 at week 2, 396.3 ± 10.4 at week 4). There were no serious adverse reactions. Conclusion: Pranlukast, an oral leukotriene antagonist, was well tolerated and was effective for the management of mild-to-moderate asthma.
