Role of Montelukast in Asthma and Allergic Rhinitis Patients

Montelukast is an orally active compound which binds with high affinity and selectivity to the CysLT1 receptor. Montelukast inhibits physiologic actions of LTD4 at the CysLT1 receptor without any agonist activity. As a result, bronchoconstriction is inhibited with decreased airway and blood eosinophil's leading to improved control over asthma and allergic rhinitis. Montelukast should be taken once daily in the evening
