Randomised, Open-label, Parallel-group Study of Therapeutic Effect of Leukotriene Modulator Montelukast Alone or Combined With Inhaled Corticosteroid on Cough Variant Asthma
This study aims to observe the therapeutic effect of leukotriene modulator montelukast alone or combined with inhaled corticosteroid(ICS) on cough variant asthma(CVA). The investigators hypothesize: 1. Cough score and cough reflex sensitivity will be improved after treatment with montelukast, inhaled corticosteroid/β2 agonist(ICS/LABA), and two combinations. 2. Combination of leukotriene modulator and inhaled corticosteroid/β2 agonist may have better efficacy when compared to montelukast, corticosteroid/β2 agonist alone while MON, is comparable to symbicort.
