Chronic obstructive pulmonary disease (COPD) is a progressive lung condition characterized by airflow limitation and inflammation. It affects millions of people worldwide and is a leading cause of morbidity and mortality. The management of COPD involves various treatment strategies, including pharmacotherapy. One such medication that has shown promise in the treatment of COPD is Montelukast.

Understanding Montelukast

Montelukast is a leukotriene receptor antagonist (LTRA) that is primarily used in the treatment of asthma. It works by blocking the action of leukotrienes, which are inflammatory mediators involved in the pathophysiology of asthma. However, recent research has suggested that Montelukast may also have beneficial effects in the management of COPD.

Mechanism of Action

In COPD, inflammation plays a crucial role in the progression of the disease. Leukotrienes, similar to asthma, contribute to the inflammatory response in COPD. Montelukast acts by inhibiting the binding of leukotrienes to their receptors, thereby reducing inflammation and its detrimental effects on the airways. This mechanism of action makes Montelukast a potential therapeutic option for COPD patients.

Evidence Supporting Montelukast in COPD

Several studies have investigated the efficacy of Montelukast in COPD management. A randomized controlled trial published in the New England Journal of Medicine found that Montelukast improved lung function and reduced exacerbations in patients with COPD. Another study published in the European Respiratory Journal showed that Montelukast reduced airway inflammation and improved symptoms in COPD patients. These findings suggest that Montelukast may be a valuable addition to the treatment arsenal for COPD.

Benefits of Montelukast

1. Anti-inflammatory Effects: Montelukast’s ability to inhibit leukotrienes provides anti-inflammatory benefits, which can help reduce airway inflammation in COPD patients.

2. Improved Lung Function: Studies have shown that Montelukast can improve lung function by increasing forced expiratory volume (FEV1) and forced vital capacity (FVC), two important measures of lung health.

3. Reduced Exacerbations: COPD exacerbations can lead to a decline in lung function and overall quality of life. Montelukast has been shown to reduce the frequency and severity of exacerbations, leading to improved disease control.

4. Symptom Relief: Montelukast has demonstrated its efficacy in relieving symptoms such as cough, wheezing, and shortness of breath in COPD patients.

5. Combination Therapy: Montelukast can be used in combination with other COPD medications, such as long-acting bronchodilators, to provide a comprehensive approach to disease management.

Considerations and Side Effects

While Montelukast has shown promise in COPD treatment, it is important to consider individual patient characteristics and potential side effects. Common side effects of Montelukast include headache, gastrointestinal disturbances, and fatigue. It is essential to consult with a healthcare professional before starting any new medication.


Montelukast, a leukotriene receptor antagonist primarily used in asthma, has emerged as a potential treatment option for COPD. Its anti-inflammatory effects, improvement in lung function, and reduction in exacerbations make it a valuable addition to the COPD management toolkit. However, further research is needed to fully understand its long-term efficacy and safety profile in COPD patients. As always, it is important to consult with a healthcare professional to determine the most appropriate treatment plan for individual COPD patients.
