How Glemont 10mg Tablet Works

Glemont 10mg Tablet contains montelukast, a leukotriene receptor antagonist that helps prevent and control asthma symptoms and relieve allergic rhinitis. Glemont 10mg Tablet works by blocking the action of leukotrienes, natural inflammatory chemicals released by the body in response to allergens and other triggers. Leukotrienes cause the airways to become swollen, tighten, and produce excess mucus, making breathing difficult. By preventing these chemicals from attaching to their receptors, Glemont 10mg Tablet helps reduce airway inflammation, keeps the breathing passages open, and decreases the body's allergic response. Together, these actions help prevent asthma symptoms, improve breathing, and relieve allergy symptoms such as sneezing, a runny nose, and nasal congestion.
