What is Montelukast?

Montelukast, marketed under the brand name Singulair, is a medication primarily used to manage and prevent symptoms of asthma and allergic rhinitis (hay fever). It belongs to a class of drugs known as leukotriene receptor antagonists (LTRAs).

How Montelukast Works

Montelukast works by blocking leukotrienes, which are chemicals in the body that cause inflammation, bronchoconstriction (tightening of the muscles around the airways), and mucus production. By inhibiting these chemicals, Montelukast helps to reduce inflammation and relax the airways, making it easier to breathe.

Common Uses

Asthma Management: Montelukast is often prescribed as a long-term treatment to control and prevent asthma symptoms, such as wheezing and shortness of breath. It is not intended for immediate relief of acute asthma attacks.
Allergic Rhinitis: For individuals suffering from seasonal or perennial allergic rhinitis, Montelukast can help alleviate symptoms like sneezing, runny nose, and nasal congestion.
Exercise-Induced Bronchoconstriction: Montelukast is also used to prevent breathing problems that occur during or after exercise.

Administration and Dosage

Montelukast is typically taken once daily, with or without food. The dosage may vary based on the patient’s age and the condition being treated. It is available in various forms, including tablets, chewable tablets, and granules.

Benefits and Considerations

Montelukast offers a convenient, once-daily option for managing chronic respiratory conditions.
