Leukotriene receptor antagonists are indicated for which type of asthma?

Leukotriene receptor antagonists are primarily indicated for the management of persistent asthma. This includes both mild and moderate persistent asthma, where maintenance therapy is necessary to control symptoms and reduce the frequency of exacerbations. Leukotriene receptor antagonists work by blocking the action of leukotrienes, which are substances in the body that contribute to inflammation and bronchoconstriction in asthma.

Using these medications can help improve lung function, control daytime and nighttime symptoms, and reduce reliance on rescue inhalers among patients with persistent asthma. They can also be used as part of a combination therapy with inhaled corticosteroids to enhance control of the condition.

While they can provide benefits across a range of severity, their role is particularly crucial in persistent asthma where consistent management is required rather than solely symptomatic relief. Other options suggesting limited use to children or only during severe instances do not reflect the comprehensive role leukotriene receptor antagonists can play in asthma management across different ages and severity levels.
