Why Is Montelukast Used for Asthma?

Asthma is a chronic disease that affects your airways, which are the tubes that carry air into and out of your lungs. If you have asthma, the inside walls of your airways are inflamed (swollen). The inflammation makes the airways sensitive, and they tend to react strongly to things that you are allergic to or find irritating (see Asthma Triggers). When the airways react, they narrow, and less air flows to your lungs. This is called bronchospasm and causes asthma symptoms, including:
 
  • Wheezing (a whistling sound when you breathe)
  • Coughing
  • Tightness in the chest
  • Trouble breathing.
     
While there is no asthma cure, the condition can be controlled. There are many different asthma treatments, including fast-acting "rescue medications" for treating an asthma attack and longer-acting "controller medications" used to prevent them. Montelukast is a controller medication, used to help prevent asthma attacks but not to treat them. Everyone who takes an asthma medication, including montelukast, should also have a rescue medication (such as an albuterol inhaler) available for emergencies.
