Which drug class is primarily used for prophylactic treatment of asthma by blocking leukotrienes?

Leukotriene Inhibitors are specifically designed to prevent asthma attacks by blocking the action of leukotrienes, which are inflammatory compounds in the body. By inhibiting these molecules, this drug class reduces bronchoconstriction and inflammation in the airways, resulting in improved respiratory function and reduced asthma symptoms.

The effectiveness of Leukotriene Inhibitors in prophylactic treatment is critical in managing chronic asthma, as they help maintain control over symptoms and prevent exacerbations that can lead to emergency situations. This targeted action distinguishes them from other classes of drugs that may serve different purposes in respiratory management or treat other conditions unrelated to asthma.
