Pharmacotherapy of asthma in children, with special reference to leukotriene receptor antagonists.
Asthma in adults is generally recognized as a chronic inflammatory airway disease, although this association is less well established in childhood asthma. Thus, recent asthma guidelines have emphasized that asthma treatment should be directed toward the underlying inflammatory aspects of the disease. The prevalence of asthma and resultant hospitalizations and deaths have increased or remained stable over the past 10 years in the United States. In part, this appears to be caused by shortcomings of available antiasthma therapeutic agents. Because these trends are particularly troublesome in children and young adults, there is a need for effective anti-inflammatory therapies that are safe and tolerable. The leukotrienes are a family of lipid mediators that appear to play an important role in the symptomology and pathogenesis of asthma. The results of clinical trials in adults with asthma demonstrated that antileukotriene drugs such as zafirlukast, montelukast, and zileuton improve pulmonary function, decrease asthma symptoms, and decrease the concomitant use of other antiasthma drugs. Most antileukotriene agents are orally bioavailable and well tolerated, offering the potential for improved patient compliance. Montelukast and zafirlukast have received approval for use in pediatric asthma patients, and approval of zafirlukast in this patient population is pending.
