Which of the following medications is used as a leukotriene modifier in asthma management?

Montelukast is classified as a leukotriene receptor antagonist, which means it blockades the action of leukotrienes in the body. Leukotrienes are inflammatory mediators that play a significant role in the pathophysiology of asthma by causing bronchoconstriction, increased mucus production, and airway inflammation. By inhibiting these mediators, montelukast helps to reduce asthma symptoms and improve overall respiratory function.

Leukotriene modifiers like montelukast are particularly useful in the management of chronic asthma, as they provide a different therapeutic approach compared to other classes of asthma medications, such as beta-agonists or corticosteroids. They are often used in conjunction with other asthma treatments for optimal control of the condition.

The other medications listed serve different purposes in asthma management. Albuterol is a short-acting beta-agonist that provides rapid relief of acute asthma symptoms through bronchodilation but does not act on leukotrienes. Theophylline, a methylxanthine, has bronchodilator effects but its use is limited due to side effects and the need for monitoring blood levels. Cromolyn is a mast cell stabilizer that helps prevent asthma attacks but does not have a direct effect on leukotrienes. Thus
