Leukotrienes are chemicals your body releases (for example, when you come into contact with something you’re allergic to). They can cause: 1. Coughing. 2. Extra mucus and fluid in your chest and throat. 3. Inflammation or swelling in your airway. 4. Tight muscles in your airway. 5. Tightness in your chest. 6. Wheezing or difficulty breathing.
Leukotriene modifiers, also called leukotriene receptor antagonists or leukotriene synthesis inhibitors, are medications that block the effect of leukotrienes or stop your body from producing them. These drugs are used to prevent or lessen the symptoms of: 1. Allergies (allergic rhinitis). 2. Allergic asthma. 3. Exercise-induced asthma.
Names of specific leukotriene modifiers include: 1. Montelukast (Singulair®). 2. Zafirlukast (Accolate®). 3. Zileuton (Zyflo®). All three are used to treat asthma, but only montelukast is approved to treat allergic rhinitis.
Montelukast and zafirlukast are leukotriene receptor antagonists. They block the effects of leukotrienes. Zileuton is a leukotriene synthesis inhibitor. It prevents the body from making leukotrienes.
Leukotriene modifiers are taken orally (by mouth), usually a tablet. They should be taken every day, whether you’re having trouble breathing or not. That’s because they’re used to help prevent breathing difficulty, not to treat an allergic reaction or asthma attack. Your healthcare provider will give you specific instructions about: 1. Dose (how mu...
Leukotriene modifiers can help you: 1. Breathe more easily. 2. Exercise despite a breathing condition. 3. Keep your airway open. 4. Lessen mucous in your chest and throat. 5. Prevent breathing trouble, such as allergic reactions and asthma attacks. 6. Reduce the number and severity of reactions and attacks.
Some leukotriene modifiers can cause liver damage. If you already have liver problems, you may not be able to take these medications. Your healthcare provider may order blood tests when you’re taking a leukotriene modifier to make sure your liveris safe.
Leukotriene modifiers are generally safe, but they can cause side effects, including: 1. Cold symptoms, such as cough, sore throat or runny nose. 2. Diarrhea. 3. Ear infection. 4. Fatigue (tiredness). 5. Flu-like symptoms, such as fever. 6. Headache. 7. Heartburn. 8. Itchy skin or rash. 9. Lack of appetite. 10. Nausea. 11. Stomach pain. If you expe...
Leukotriene modifiers may interact with other medications, so it’s important to tell your healthcare provider about everything you take. The drugs might interact with: 1. Alpelisib, dabrafenib or enzalutamide (treatments for cancer). 2. Erythromycin and rifapentine (antibiotics that treat bacterial infections). 3. Loxapine (a drug to treat mental h...
Jun 4, 2023 · The main indication for leukotriene receptor antagonists is in treating chronic asthma. Leukotrienes are synthesized from arachidonic acid by the action of 5-lipoxygenase in many inflammatory cells in the airways. [9] Arachidonic acid is released from cell membrane phospholipids mainly by phospholipase A2. [10]

Leukotriene synthesis inhibitors, such as zileuton, block the enzyme, 5-lipoxygenase, which is necessary for the formation of leukotrienes. Montelukast, zafirlukast, and zileuton may be considered for the treatment of asthma. Only montelukast is approved to treat allergic rhinitis, allergic conjunctivitis, and allergies as well.
