Montelukast is a medication used in the treatment of asthma and allergies. It is a leukotriene receptor antagonist which helps by blocking the action of leukotrienes, a type of chemical released in the body during an allergic reaction or asthma attack. Montelukast can be used to prevent the symptoms of asthma and allergies, such as difficulty breathing, wheezing, and coughing. It is also used to prevent exercise-induced bronchoconstriction (EIB). Montelukast is taken orally, usually once a day.
Montelukast is a medication primarily used to manage asthma and allergy symptoms. Here's a breakdown of its key features:
Conditions it treats:
- Asthma: Montelukast helps control and prevent chronic asthma symptoms like wheezing and shortness of breath. It's not a quick reliever for sudden asthma attacks, but it can help reduce the frequency of needing them.
- Allergic rhinitis (hay fever): It relieves symptoms of seasonal and perennial allergic rhinitis, including sneezing, stuffy nose, runny nose, and itchy nose. However, it's typically used only when other allergy medications aren't effective or suitable.
- Exercise-induced bronchoconstriction: This medication can prevent breathing difficulties triggered by exercise in adults and children over 6 years old.
How it works:
Montelukast belongs to a drug class called leukotriene receptor antagonists (LTRAs). Leukotrienes are natural substances produced by the body that contribute to inflammation in asthma and allergies. By blocking the action of leukotrienes, Montelukast helps reduce inflammation in the airways, easing breathing difficulties and allergy symptoms.
Dosage and administration:
Montelukast comes in various forms like tablets, chewable tablets, and granules. The dosage and frequency depend on the condition being treated and the patient's age. It's usually taken once daily, with or without food.
Important points to remember:
- Montelukast is a long-term medication and needs to be taken regularly for it to be effective.
- It's not a substitute for quick-relief inhalers used during sudden asthma attacks.
- It can interact with other medications, so consult your doctor before starting Montelukast, especially if you're already on other medications.
