A statement about montelukast that is correct?

• A. It is a short-acting bronchodilator
• B. It has anti-inflammatory effects and is used for prophylaxis and maintenance only
• C. It is a mucolytic
• D. It is a corticosteroid

Answer: (B)

Montelukast works by blocking leukotriene receptors in the airways, which reduces leukotriene-driven inflammation, bronchoconstriction, mucus production, and airway edema. This anti-inflammatory action underlies its use for ongoing prophylaxis and maintenance in asthma (and also for allergic rhinitis and exercise-induced bronchoconstriction prophylaxis). It does not provide rapid relief of acute bronchospasm, so it is not a short-acting bronchodilator. It is not a mucolytic and not a corticosteroid, so it isn’t used as a rescue therapy or as a steroid replacement.
