In patients with mild persistent asthma, low-dose orally inhaled corticosteroids considered first-line agents for long-term control.43 74 Alternative agents, including certain leukotriene modifiers (i.e., zafirlukast, montelukast), may be used but are less effective than inhaled corticosteroids and are not preferred as initial therapy.43 74 76

In patients with moderate persistent asthma, low-dose inhaled corticosteroids with a long-acting inhaled β2-agonist bronchodilator (e.g., salmeterol, formoterol) or monotherapy with medium-dose inhaled corticosteroids preferred.43 74 However, the National Asthma Education and Prevention Program (NAEPP) recommends that beneficial effects of long-acting inhaled β2-agonists be weighed carefully against increased risk of severe asthma exacerbations and asthma-related deaths associated with daily use of such agents.74

Alternative agents, including certain leukotriene modifiers (i.e., zafirlukast, montelukast), can be added to a low dosage of inhaled corticosteroid for treatment of moderate persistent asthma, but these options are less effective.43 74 Considerations favoring combination with orally inhaled corticosteroids include intolerance to long-acting β2-adrenergic agonists, marked preference for oral therapy, and demonstration of superior responsiveness to these leukotriene modifiers.74

In adults and children ≥5 years of age with severe persistent asthma, NAEPP and the Global Initiative for Asthma (GINA) state that maintenance therapy with inhaled corticosteroids at medium to high dosages and adjunctive therapy with a long-acting inhaled β2-agonist is preferred.43 74 Alternatives to a long-acting inhaled β2-agonist in such patients receiving medium-dose inhaled corticosteroids include certain leukotriene modifiers (i.e., zafirlukast, montelukast), but these agents are generally not preferred.43 74

Therapy with zafirlukast may be especially useful in patients who are unable or unwilling to comply with therapy using inhaled drugs (e.g., children).11 12 22 23 25 53 74
