Which drug is a leukotriene receptor antagonist used for asthma?

• A. Montelukast
• B. Albuterol
• C. Prednisone
• D. Pulmicort

Answer: (A)

Leukotriene receptor antagonists block the receptors for leukotrienes in the airways, which reduces inflammation, bronchoconstriction, and mucus production that contribute to asthma symptoms. Montelukast is the oral leukotriene receptor antagonist commonly used for long-term asthma control, including exercise-induced symptoms, and it can be taken daily as a controller medication. It’s not a quick-relief rescue drug. The other drugs do different roles: albuterol is a fast-acting bronchodilator for acute symptoms, prednisone is a systemic anti-inflammatory steroid, and Pulmicort is an inhaled corticosteroid for routine control.
