Therapeutic Uses of Singulair
Singulair’s Role in Asthma and Allergic Rhinitis Treatment
Singulair, or montelukast sodium, is widely recognized for its efficacy in the management of asthma and the relief of symptoms associated with allergic rhinitis. As a leukotriene receptor antagonist, it effectively reduces the bronchoconstriction and inflammation that are hallmarks of asthma. Moreover, it is equally beneficial in treating nasal congestion, sneezing, and runny nose caused by seasonal or perennial allergies.
Mechanism of Action
Singulair operates by blocking leukotrienes, substances in the body that trigger allergy and asthma symptoms. By binding to leukotriene receptors, it prevents these components from causing the swelling and bronchial constriction associated with asthma and allergic rhinitis.
