What class of medication does montelukast belong to?

Montelukast is classified as a leukotriene receptor antagonist. This type of medication works by blocking leukotrienes, which are chemicals in the immune response that cause inflammation, bronchoconstriction, and mucus production in the airways. By inhibiting these leukotrienes, montelukast helps to reduce inflammation and relax the airways, making it easier for individuals with asthma or allergic rhinitis to breathe.

This mechanism of action is distinct from other classes of medications. Corticosteroids reduce inflammation through different pathways and are often used for their anti-inflammatory properties, while antihistamines primarily target histamine receptors to alleviate allergy symptoms. Beta-agonists work by stimulating beta-adrenergic receptors, leading to bronchodilation, but do not affect leukotriene activity directly. Thus, montelukast's specific role in blocking leukotriene action confirms its classification as a leukotriene receptor antagonist.
