Kamoton 20s Tab

Levocetirizine and Montelukast Sodium Tablet have a combined mechanism of action to provide relief from allergic symptoms. Levocetirizine is a potent and highly selective antagonist of the H1 histamine receptor, which is responsible for mediating the symptoms of allergic reactions. By blocking this receptor, levocetirizine prevents the release of histamine-induced inflammatory mediators, reducing symptoms such as sneezing, itching, and runny nose. Montelukast sodium, on the other hand, is a leukotriene receptor antagonist. It specifically blocks the cysteinyl leukotriene receptor, CysLT1. Leukotrienes are inflammatory mediators released by mast cells and play a crucial role in the pathophysiology of asthma and allergic rhinitis. By inhibiting the action of leukotrienes, montelukast reduces airway inflammation, bronchoconstriction, and nasal congestion. Together, the combination of levocetirizine and montelukast sodium effectively targets multiple pathways involved in allergic responses, providing comprehensive relief from allergy symptoms.
