Which medication can prevent exercise-induced asthma?

Montelukast is a leukotriene receptor antagonist that can help prevent exercise-induced asthma. It works by blocking the action of leukotrienes, which are inflammatory chemicals that contribute to asthma symptoms like bronchoconstriction, mucus production, and airway inflammation. By inhibiting these effects, Montelukast can reduce the likelihood of asthma symptoms occurring during or after physical activity.

Using Montelukast as a preventive measure is particularly beneficial because it can be taken daily, allowing for ongoing control of airway inflammation and responsiveness, thus decreasing the risk of exercise-induced bronchospasm. This makes it a suitable option for individuals who experience asthma symptoms triggered by exercise.

Other medications might have roles in asthma management, but they either operate differently or are primarily for acute treatment rather than prevention of exercise-induced asthma. For instance, Albuterol is a short-acting bronchodilator used for quick relief during an asthma attack rather than prevention, and Cromolyn Sodium and Nedocromil Sodium are used less frequently today for regular asthma control.
