Is singular a corticosteroid

Yes, Singulair (montelukast) is not a corticosteroid; it is a leukotriene receptor antagonist used primarily to manage Asthma and allergic rhinitis. It works by blocking the action of leukotrienes, substances in the body that cause inflammation, bronchoconstriction, and mucus production. While it is effective in treating respiratory conditions, it functions differently from corticosteroids, which reduce inflammation through a different mechanism.
