Used primarily in the treatment of asthma, this compound functions as a 5-lipoxygenase inhibitor, blocking the production of leukotrienes—substances in the body that cause airway inflammation and constriction. By reducing leukotriene levels, it helps prevent asthma symptoms such as wheezing, shortness of breath, and nighttime awakenings. It is prescribed for the long-term management of chronic asthma, particularly in patients who have demonstrated insufficient control with other therapies. It is not intended for immediate relief of acute asthma attacks. Its use supports improved lung function and reduced frequency of asthma exacerbations when taken regularly as directed.
