Montelukast Sodium is a highly potent and selective antagonist of the CysLT1 receptor (with an IC50 of less than 5 nM), exhibiting no significant effect on the CysLT2 receptor. It functions by competitively inhibiting leukotrienes, particularly LTD4, a key mediator involved in pulmonary and immune system pathways. In studies on rat colitis, Montelukast Sodium has been shown to enhance PGE2 (Prostaglandin E2) production while reducing COX-2 expression. Due to its specific mechanism of action, it is not effective for treating acute asthma attacks but is suitable for long-term management. Additionally, it does not interfere with other asthma medications like theophylline. Another drug in the same class is zafirlukast (Accolate), which also targets leukotriene receptors.

Application&Function

Montelukast is a potent oral leukotriene receptor antagonist that effectively improves asthma inflammation by inhibiting leukotrienes, which are released during inflammatory responses like allergen exposure. It selectively targets type I cysteinyl leukotriene receptors (CysLT1), blocking the effects of inflammatory mediators (LTC4, LTD4, LTE4) without agonist activity. Clinically, it is used for the prevention and long-term treatment of asthma in patients aged 15 and older, including daytime and nighttime symptoms, aspirin-sensitive asthma, and exercise-induced bronchoconstriction. It also alleviates symptoms of seasonal allergic rhinitis, such as sneezing, nasal congestion, runny nose, and itching.
