Mechanism of action

Montelukast is a selective antagonist of the cysteinyl leukotriene type-1 (CysLT1) receptor. Leukotrienes are inflammatory mediators released by mast cells and eosinophils that cause airway constriction, mucus secretion, and eosinophil recruitment. By blocking these receptors, montelukast reduces airway inflammation and improves airflow in asthma and allergic rhinitis.
