Montelukast is used to treat several respiratory and allergy-related conditions.
Conditions Treated by Montelukast
Montelukast, available as a film-coated tablet, chewable tablet, or oral granules, is approved by the FDA for the following:
- Chronic Asthma: Montelukast is a maintenance treatment for chronic asthma.
- Prophylaxis and Prevention of Exercise-Induced Bronchoconstriction: It can prevent the narrowing of airways caused by exercise.
- Allergic Rhinitis: Both seasonal and perennial allergic rhinitis symptoms are relieved by montelukast.
Detailed Breakdown
| Condition | Description |
|---|---|
| Chronic Asthma | Long-term management of asthma symptoms. Helps reduce inflammation and airway constriction. |
| Exercise-Induced Bronchoconstriction | Prevents airway narrowing that occurs during or after physical activity. |
| Seasonal Allergic Rhinitis | Alleviates symptoms like sneezing, runny nose, and itchy eyes that occur during specific seasons (e.g., pollen season). |
| Perennial Allergic Rhinitis | Relieves similar symptoms to seasonal rhinitis but occur year-round due to allergens like dust mites or pet dander. |
How Montelukast Works
Montelukast works by blocking the action of leukotrienes, substances in the body that cause inflammation, airway constriction, and mucus production. By blocking these substances, montelukast helps reduce symptoms associated with asthma and allergic rhinitis.
Practical Insights
- Montelukast is often used as a daily maintenance medication for asthma to prevent symptoms.
- It can be taken before exercise to prevent exercise-induced bronchoconstriction.
- Montelukast is an alternative to antihistamines for managing allergic rhinitis symptoms.
- It can be used in children and adults for the approved conditions.
