Montelukast is primarily used for which of the following conditions?

• A. Acute asthma attacks
• B. Long-term asthma control
• C. Short-term allergic reactions
• D. Mucus hypersecretion

Answer: (B)

Montelukast is primarily utilized for long-term asthma control because it functions as a leukotriene receptor antagonist. By blocking the action of leukotrienes, which are inflammatory mediators that can cause bronchoconstriction and mucus production, montelukast helps to reduce inflammation, relax airway smooth muscle, and decrease mucus secretion over time. This makes it particularly effective for managing chronic asthma symptoms and preventing asthma attacks.

In contrast, the other choices are not aligned with the primary use of montelukast. Acute asthma attacks typically require fast-acting bronchodilators rather than a long-term controller like montelukast. Short-term allergic reactions generally respond to antihistamines or corticosteroids, not leukotriene receptor antagonists. Mucus hypersecretion may require different types of medications aimed specifically at thinning mucus rather than blocking leukotriene effects.
