Contain the active ingredient : Montelukast, which is a type of medicine known as a leukotriene receptor antagonist. It works by blocking the action of leukotrienes, which are chemicals released by the body as part of allergic and inflammatory reactions.
Leukotrienes are released from the lungs in people with asthma, causing inflammation and increased mucus production in the airways. They also cause the muscles lining the airways to contract, which narrows the airways. All of this makes it difficult for air to get in and out of the lungs.
Montelukast blocks leukotriene receptors in the lungs and, as a result, blocks the actions of the leukotrienes. This prevents the excess mucus production, inflammation and narrowing of the airways and so prevents asthma attacks. It is also useful for preventing asthma triggered by exercise.
Leukotrienes are also released from the nasal passages when people with seasonal allergies, such as hayfever, are exposed to substances that trigger their allergy (allergens, eg pollen). The leukotrienes contribute to the symptoms of hayfever, such as a runny or blocked nose, sneezing and itchy nose. This medicine blocks the effect of leukotrienes in the nose and so can relieve hayfever symptoms in people with asthma who also suffer from hayfever.
What is it used for?
Asthma, including asthma mainly triggered by exercise.
The medicine can also provide relief from hayfever symptoms in people with asthma who also suffer from hayfever (seasonal allergic rhinitis).
Montelukast is used for people whose asthma is not fully controlled by using regular inhaled corticosteroids and short-acting beta agonist relievers such as salbutamol. It is used in addition to these medicines.
Montelukast should be taken regularly to prevent asthma attacks. You should continue to take it even when your symptoms are under control.
