Used primarily as an anti-asthmatic agent, it acts as a thromboxane A2 receptor antagonist, helping to prevent bronchoconstriction and reduce airway inflammation. It is effective in managing chronic asthma by improving lung function and decreasing the frequency of asthma symptoms. Also exhibits potential in reducing cough and mucus production in respiratory conditions. Some studies suggest benefits in improving exercise tolerance and preventing allergen-induced bronchospasm. Investigated for possible anti-inflammatory and antifibrotic effects in lung tissues, supporting its role in long-term respiratory management.
