Singulair information
What is Singulair used for?
Singulair tablets (generic Singulair) are used for treatment of asthma, including management of chronic asthma, preventing exacerbations of asthma, day-time and night-time symptoms and exercise-induced asthma, and to prevent but not treat asthma attack. Montelukast tablets are also used to treat seasonal allergy to pollen, also known as hay fever, and perennial allergy, such as to animal fur, mould and house dust mites, which cause allergic rhinitis with symptoms including nasal congestion, runny itchy nose, sneezing, tearing, itchy, red, and puffy eyes and problems sleeping.
How does Singulair work?
Singulair tablets contain montelukast sodium, which is a selective and orally active (can be taken in tablet form) leukotriene receptor antagonist, which means that it binds to specific receptors on the cells of the airways and also cells in the airways that are involved in the inflammatory process (like macrophages), and inhibits the action of leukotrienes, (chemicals produced by inflammatory cells like mast cells that mediate inflammation) on these cells. Leukotrienes are involved in the pathophysiology of asthma and allergic rhinitis. In asthma leukotriene-mediated effects cause bronchoconstriction (narrowing of the airways), inflammation, swelling and mucous secretion. In allergic rhinitis leukotrienes are released in the nasal passages after exposure to an allergen like pollen or house dust mites and cause irritation and inflammation. Montelukast tablets help to reduce asthma symptoms including coughing, wheezing and tightness of the chest and symptoms of allergic rhinitis lik
e nasal congestion, runny nose and sneezing.

Singulair film-coated tablets contain the active ingredient montelukast sodium, which is a leukotriene receptor antagonist that prevents leukotriene-mediated inflammation in asthma and allergic rhinitis.
Treating asthma with Singulair
Singulairtablets contain the active ingredient montelukast sodium, which is a leukotriene receptor antagonist that prevents leukotriene-mediated inflammation in asthma. Leukotrienes are chemicals that mediate inflammation and are involved in the changes that happen in the lungs that cause asthma, such as bronchoconstriction (narrowing of the airways), swelling and mucous secretion. Montelukast in Montair tablets binds to the leukotriene receptors and block the action of leukotriene in the airways, which helps to reduce asthma symptoms including coughing, wheezing and tightness of the chest. You should not use Montelukast tablets as a “reliever” or “rescue” medication for bronchospasm or if you are having an asthma attack, for this you need a fast acting bronchodilator inhaler.

Montelukast in Singulair tablets binds to the leukotriene receptors and block the action of leukotriene in the nasal passages, which helps to reduce symptoms of allergic rhinitis like nasal congestion, runny nose and sneezing.
