🔬 How This Medicine Works (Pharmacology)
Pharmacokinetics
How It Works
This medicine combines two active ingredients with different but complementary actions. Montelukast blocks cysteinyl leukotriene receptors in the airways, which reduces leukotriene-driven bronchoconstriction, mucus secretion, and airway swelling. Fexofenadine blocks peripheral histamine H1 receptors, which reduces allergy symptoms such as sneezing, itching, and runny nose. Together, they target two important chemical pathways involved in allergic inflammation and asthma symptoms.
