Used primarily in the management of asthma, this compound functions as a leukotriene receptor antagonist, helping to reduce inflammation and bronchoconstriction in the airways. It is effective in preventing exercise-induced asthma and provides relief in chronic asthma by blocking the action of leukotrienes, which are inflammatory mediators involved in allergic responses. It is also studied for its potential in treating other allergic conditions such as allergic rhinitis, offering a non-steroidal option for long-term control of symptoms.
