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 taken orally and is effective in preventing asthma symptoms, including wheezing and shortness of breath, especially in mild to moderate persistent asthma. It is not intended for immediate relief of acute asthma attacks but rather for long-term control. Often prescribed as a maintenance therapy, it helps decrease the frequency of asthma exacerbations and reduces the need for inhaled short-acting beta agonists. It may also be used in patients with aspirin-sensitive asthma, where leukotriene pathways play a significant role.
