Montelukast belongs to a class of drugs known as leukotriene receptor antagonists, and is used in mild to moderate asthma to decrease the symptoms of asthma. Singulair is used in the long-term prevention of asthma but it will not stop an acute asthma attack. In order to stop an attack you should use a fast-acting, orally inhaled airway opener such as Alupent or Proventil. For the almost 10 million adults and 6 million children in America who suffer from asthma, this is an extremely important medicine.
Moreover, this drug may aid in simplifying the sometimes difficult task of managing asthma successfully. The drug can aid in keeping bronchial airways open, thus making breathing easier. This means symptoms may be less frequent and less severe.
It is also typically used to treat the symptoms of seasonal allergies.

Treatment of Nasal Polyps
Order montelukast online to treat nasal polyps. It has been found that leukotrienes, powerful chemical substances produced by the body that promote the inflammatory response caused by allergans, are associated with the development of nasal polyps. Early studies of leukotriene-type drugs, such as Singulair, have shown improved nasal airflow and reduction in nasal polyps.
Researchers in England evaluated the use of montelukast in patients with nasal polyps and asthma who were both aspirin-sensitive and aspirin-tolerant.
In this study, patients received a three-month regimen consisting of this drug in addition to intranasal and inhaled corticosteroid.
Results from this study showed a clinical improvement in nasal polyps in 64% of aspirin-tolerant patients and 50% of aspirin-sensitive patients.
Asthma improved in both groups of patients. Singulair improvements were not related to age, sex, disease duration, or aspirin sensitivity. Researchers concluded that in some people leukotriene receptor antagonists, such as montelukast, are effective.
