Which medication is an example of a leukotriene modifier used for maintenance?

• A. Singulair
• B. Albuterol
• C. Fluticasone
• D. Ipratropium

Answer: (A)

Leukotriene modifiers block leukotrienes, inflammatory substances that contribute to bronchoconstriction and airway inflammation. They are used as ongoing maintenance therapy for asthma, not for immediate relief. Montelukast (Singulair) is a leukotriene receptor antagonist approved for daily maintenance and prevention of asthma symptoms (including exercise-induced bronchospasm). The other medications listed serve different roles: albuterol provides quick-relief bronchodilation, fluticasone is an inhaled corticosteroid for long-term control of inflammation, and ipratropium is an anticholinergic bronchodilator. Therefore, Singulair is the correct choice.
