Exercise-Induced Bronchoconstriction: Acute Prevention (EIB)

Allergic Rhinitis (AR) Symptom Relief: Seasonal & Perennial Allergic Rhinitis

Pharmacology

Montelukast inhibits the cysteinyl leukotriene receptor and is a selective and orally active leukotriene receptor antagonist (CysLT1). Arachidonic acid metabolism produces cysteinyl leukotrienes (LTC4, LTD4, LTE4), which are produced by a variety of cells, including mast cells and eosinophils. The pathophysiology of asthma and allergic rhinitis, including airway edema, smooth muscle contraction, and altered cellular activity associated with the inflammatory process, have been linked to cysteinyl leukotrienes and leukotriene receptor occupation, all of which contribute to the signs and symptoms of asthma.
