What is it used for ?
- Prevention of asthma that is mainly triggered by exercise
How does it work?
This medicine contains 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 the allergic
and inflammatory response.
Leukotrienes have effects in many areas of the
body. In the lungs, they cause inflammation and increased mucous
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 leukotrienes. This
prevents the excess mucous production, inflammation and narrowing
of the airways that occurs in asthma, and therefore prevents asthma
attacks. Montelukast should be taken regularly to prevent attacks.
You should continue to take it even when your symptoms are under
Montelukast is used for people whose asthma is
not fully controlled with regular inhaled corticosteroids or short-acting
beta agonist relievers such as salbutamol. It is also useful to
prevent asthma caused by exercise.
The medicine is available in three strengths.
Singulair 10mg tablets are suitable for adults aged 15 years and
over. Singulair Paediatric 5mg chewable tablets are suitable for
children aged 6 to 14 years, and Singulair Paediatric 4mg chewable
