What is Singulair (Montelukast)?

Montelukast belongs to the leukotriene modifier class of drugs. It reduces airway inflammation and hence helps treat asthma and allergies. It is available in the market as Singulair, Montair, Montek, Lukotas, and Montril. It can be taken orally as a chewable tablet or granules. Zafirlukast and Zileuton are two other examples of drugs in this category. Montelukast should not be used as a first line of treatment for allergic rhinitis.

Uses of Singulair

Singulair is used to treat as well as prevent asthma and allergies. It works by reducing inflammation. It decreases inflammation in the airways, which in turn makes it easier to breathe. Singulair (Montelukast) can not be used for a sudden asthma attack; use your quick-relief inhaler if you have a sudden asthma attack as prescribed by your healthcare professional.

How does it work?

Montelukast is a highly selective leukotriene receptor antagonist strongly binding to the cysteinyl leukotriene receptor for leukotrienes D4 and E4, reducing airway inflammation and swelling. It works by inhibiting the action of leukotriene D4 in the lungs, which reduces inflammation and relaxes smooth muscles, making breathing easier. The immune system’s production of leukotrienes promotes inflammation, bronchoconstriction, and mucus secretion in the airways.

How do you take Singulair?

Take Singulair (Montelukast) as prescribed by your doctor. Singulair is an oral medication that can be taken once daily, preferably in the evening, to reduce or prevent allergy and asthma symptoms. Take a single dose two hours before exercise for bronchoconstriction induced by exercise. Wait at least 24 hours before taking another dose. You can place oral granules directly into the mouth and engulf them with a spoonful of ice cream, rice, or mashed carrots. Oral granules can also be mixed with a spoonful of breast milk or baby formula for kids.
