What does it do?

Montelukast sodium is a drug that belongs to the leukotriene receptor antagonist class. It is primarily used to relieve symptoms of respiratory allergic diseases such as asthma and allergic rhinitis. It helps to reduce inflammatory responses and prevent airway constriction.

Montelukast sodium blocks the binding of a mediating inflammatory substance called leukotriene to bronchial receptors in the body. As a result, inflammation and constriction of the bronchi are reduced, leading to easier breathing. Consequently, it alleviates asthma attacks and allergy symptoms.
