Leukotriene receptor antagonists are primarily used to manage which of the following conditions?

Leukotriene receptor antagonists are primarily employed in the management of asthma and bronchoconstriction due to their mechanism of action. These medications work by blocking the effects of leukotrienes, which are inflammatory mediators that contribute to bronchoconstriction, airway edema, and mucus production in asthma. By inhibiting these receptors, leukotriene receptor antagonists help reduce airway hyperreactivity and improve lung function, making them an effective option for patients experiencing asthma symptoms.

In addition to their role in asthma management, these medications can also be helpful in preventing exercise-induced bronchoconstriction. They offer an alternative or adjunctive therapy alongside inhaled corticosteroids, particularly for patients whose asthma is not well-controlled with those agents alone.

The other options listed are not the primary uses for leukotriene receptor antagonists. For example, hypertension is commonly managed with different classes of medications such as ACE inhibitors or beta-blockers, while osteoarthritis typically requires nonsteroidal anti-inflammatory drugs (NSAIDs) or analgesics. Allergic rhinitis can be treated with antihistamines or intranasal corticosteroids but does not primarily involve leukotriene receptor antagonists as a first-line treatment. Thus, the focus of leukotriene receptor antagonists
