Leukotriene Inhibitors for Asthma and Allergies
Asthma is a chronic lung disease. When asthma strikes, airways in the lungs become swollen and constricted, causing coughing, wheezing, and difficulty breathing.
Allergic rhinitis, also called hay fever, is an allergic response by your immune system to pollens, mold, and dust. Symptoms include stuffy, runny, or itchy nose, and sneezing.
Asthma and allergic rhinitis can be triggered by many of the same allergens. And, in both conditions, leukotrienes add to the development of symptoms. Leukotrienes are chemicals that cause inflammation, mucous secretion, and constriction in your lungs.
Leukotriene inhibitors are medicines that decrease inflammation by preventing the action of leukotrienes. These types of medicines are not used to relieve acute symptoms, but can be used to prevent your symptoms from occurring.
Examples of leukotriene inhibitors that are available include:
