扎鲁司特Zafirlukast 孟鲁司特Montelukast (Singulair) Montelukast is a CysLT1 antagonist;that it blocks the action of leukotriene D4 (and secondary ligands LTC4 and LTE4)on the cysteinyl leukotriene receptor CysLT1 in the lungs and bronchial tubes by binding to it.This reduces the bronchoconstriction otherwise caused by the leukotriene and results in less inflammation. 齐留通Zileuton NH2 5-lipoxygenase inhibitor Zileuton(introduced in 1996 by Abbott Laboratories)is an active oral inhibitor of the enzyme 5-lipoxygenase,which forms leukotrienes from arachidonic acid.Zileuton is indicated for the prophylaxis and chronic treatment of asthma in adults and children 12 years of age and older. Zileuton is not indicated for use in the reversal of bronchospasm in acute asthma attacks.Therapy with zileuton can be continued during acute exacerbations of asthma.扎鲁司特 Zafirlukast 孟鲁司特 Montelukast (Singulair) Montelukast is a CysLT1 antagonist; that it blocks the action of leukotriene D4 (and secondary ligands LTC4 and LTE4) on the cysteinyl leukotriene receptor CysLT1 in the lungs and bronchial tubes by binding to it.
