Used primarily in the treatment of asthma and allergic rhinitis, this compound functions as a leukotriene receptor antagonist, helping to reduce inflammation in the airways and control symptoms like wheezing and shortness of breath. It is commonly prescribed for long-term asthma management, especially in patients with exercise-induced bronchoconstriction. The compound is also effective in relieving symptoms of seasonal allergies, such as sneezing, runny nose, and nasal congestion. Its oral formulation makes it suitable for daily use in both adults and children, offering a non-steroidal alternative for chronic respiratory conditions.
