🔬 How This Medicine Works (Pharmacology)
Pharmacokinetics
How It Works
This medicine combines two active ingredients with complementary mechanisms. Montelukast selectively blocks cysteinyl leukotriene receptor type 1 (CysLT1), preventing leukotriene-mediated bronchoconstriction, mucus secretion, and airway inflammation. Fexofenadine is a second-generation antihistamine that selectively antagonizes peripheral histamine H1 receptors, reducing symptoms of allergic rhinitis such as sneezing, rhinorrhea, and itching. Together, they address both histamine- and leukotriene-driven allergic pathways.
