How Fexofenadine + Montelukast works
- Fexofenadine + Montelukast is an anti-allergic agent.
- Fexofenadine is an antihistamine. It works by blocking the action of histamine, which is a substance released during an allergic reaction. By blocking histamine, fexofenadine helps to reduce symptoms associated with allergies, such as sneezing, itching, runny nose, watery eyes, and nasal congestion.
- Montelukast is a leukotriene receptor antagonist. It works by blocking the action of leukotrienes, the chemicals produced by the body during an allergic or inflammatory response. Leukotrienes cause inflammation and narrowing of the airways in conditions such as asthma and allergic rhinitis. By blocking the effects of leukotrienes, montelukast helps to prevent asthma symptoms and improve breathing.
