Efficacy of antileukotriene agents in asthma management.
OBJECTIVE: This article reviews information on the role of three antileukotrienes (anti-LTs), montelukast, zafirlukast, and zileuton, in the management of asthma. After reading this article, readers should have an understanding of the efficacy of anti-LTs in specific patient populations. DATA SOURCES: Relevant and appropriately controlled clinical studies on the efficacy of anti-LTs were used. Only literature in the English language was reviewed. STUDY SELECTION: Material was taken from peer-reviewed journals and published abstracts. RESULTS: The efficacy of anti-LTs has been established in numerous randomized, controlled, multicenter trials involving patients with mild-to-moderate disease. These agents reduce asthma symptoms, beta2-agonist use, and asthma exacerbations, in addition to improving pulmonary function. The anti-LTs are also effective when added to low-dose or high-dose corticosteroid regimens in symptomatic asthma patients. They have proven efficacy in patients with aspirin-sensitive asthma, and they appear able to reduce nasal congestion in asthma patients with concomitant upper airway symptoms. Some anti-LTs have been shown to be effective in pediatric asthma patients. CONCLUSIONS: In reviewing available clinical results as well as real-world experience in managing asthma patients, the Antileukotriene Working Group concludes that anti-LTs may be used in patients with mild persistent asthma as well as in combination with other asthma medications at all levels of disease severity for long-term maintenance of asthma control.[1]References
