Montelukast is a selective and orally active leukotriene receptor antagonist that blocks the cysteinyl leukotriene receptor (CysLT1). Cysteinyl leukotrienes (LTC4, LTD4, LTE4), released from mast cells and eosinophils, contribute to airway inflammation, smooth muscle contraction, and edema, leading to the symptoms of asthma and allergic rhinitis. By inhibiting these leukotrienes, Montelukast helps reduce inflammation and associated symptoms.
