Montelukast: Comprehensive Overview
Montelukast is a selective leukotriene receptor antagonist (LTRA) widely employed for the prophylactic and maintenance treatment of asthma and the alleviation of allergic rhinitis symptoms. It acts by competitively inhibiting leukotriene binding to receptors on airway smooth muscles and vascular endothelium. Leukotrienes are potent inflammatory mediators that contribute to asthma by promoting bronchoconstriction, mucus secretion, and airway oedema. By mitigating these effects, Montelukast reduces airway inflammation, improves airflow, and provides symptomatic relief, serving as a vital oral adjunct or alternative to inhaled therapies.
