Leukotriene Receptor Antagonists: Uses, Common Brands, and Safety Info

Leukotriene receptor antagonists (LTRAs) are drugs used to manage asthma and allergies by blocking inflammatory chemicals. Common brands include Singulair, Accolate, and Zyflo. LTRAs are generally safe, but may cause side effects such as headache and gastrointestinal disturbances. Rarely, they may be associated with neuropsychiatric events. Consult a healthcare provider for personalized advice.

Leukotriene Receptor Antagonists

Leukotriene receptor antagonists (LTRAs) are a class of drugs primarily used in the management of asthma and allergies. They work by blocking the action of leukotrienes, which are inflammatory chemicals released by the body in response to allergens or other triggers. LTRAs provide relief from symptoms such as wheezing, shortness of breath, chest tightness, and nasal congestion.


Leukotriene receptor antagonists are commonly prescribed for the following conditions:

  • Asthma: LTRAs are often used as an add-on therapy for people with persistent asthma, especially in those who do not achieve adequate control with other asthma medications.

  • Allergic Rhinitis: LTRAs can help alleviate symptoms of allergic rhinitis, including nasal congestion, sneezing, and itching.

  • Exercise-Induced Bronchoconstriction: These drugs can also be beneficial for individuals who experience asthma symptoms triggered by exercise.

The use of LTRAs should always be under the guidance and prescription of a healthcare professional. They may be used as a monotherapy or in combination with other asthma medications, depending on the individual's specific needs and severity of symptoms.

Common Brands

There are several brands of leukotriene receptor antagonists available on the market. Some commonly prescribed LTRAs include:

  • Montelukast (brand name: Singulair)

  • Zafirlukast (brand name: Accolate)

  • Zileuton (brand name: Zyflo)

It is important to note that brand names may vary depending on the country and region. Your healthcare provider will prescribe the most suitable option for you based on your specific medical condition.


Leukotriene receptor antagonists are generally considered safe and well-tolerated when used as directed. However, like any medication, they may have potential side effects or contraindications. It is essential to discuss your medical history and any existing medications with your healthcare provider before starting LTRAs.

Some possible side effects of LTRAs include:

  • Headache

  • Gastrointestinal disturbances

  • Flu-like symptoms

  • Increased liver enzymes (rare)

In very rare cases, leukotriene receptor antagonists have been associated with neuropsychiatric events such as agitation, aggression, suicidal thoughts, and depression. However, the overall risk of these adverse effects is extremely low.

It is crucial to follow the prescribed dosage and inform your healthcare provider about any concerns or unusual symptoms you experience while taking LTRAs. If you have a history of any liver disease or are pregnant or breastfeeding, your healthcare provider should evaluate the potential risks and benefits of using LTRAs in these situations.

Always consult your healthcare provider for personalized advice on the use of leukotriene receptor antagonists, and never stop or change your medication without proper medical guidance.
