What Is Montelukast?

Montelukast is a widely used allergy and asthma medication designed to help relieve symptoms such as sneezing, runny nose, itchy nose, nasal congestion, and breathing difficulty. It is commonly prescribed for:

• Allergic rhinitis (hay fever)

• Asthma symptom relief

• Prevention of exercise-induced bronchospasm

Montelukast helps improve breathing, reduce inflammation in the airways, and control allergy-related discomfort.

How Montelukast Works

Classification: Leukotriene Receptor Antagonist (LTRA)

Montelukast works by blocking leukotrienes, inflammatory chemicals released by immune cells like eosinophils and mast cells. These chemicals contribute to airway swelling, mucus production, and allergy symptoms. By blocking their receptors, Montelukast helps keep airways open and reduces allergic reactions.
