Leukotriene receptor antagonists are commonly indicated for which condition?

Leukotriene receptor antagonists, such as montelukast, are specifically indicated for the management of asthma. These medications work by blocking the action of leukotrienes, which are inflammatory mediators that contribute to bronchoconstriction, mucus production, and airway hyperreactivity in asthma. By inhibiting leukotriene receptors, these drugs help to reduce inflammation and improve airflow, making them effective in both the treatment of chronic asthma and the prevention of exercise-induced bronchospasm.

In addition to asthma, leukotriene receptor antagonists may also be used for allergic rhinitis, but their primary and most common indication is asthma management. This mechanism of action differentiates them from treatments for conditions such as hypertension, diabetes, or hyperlipidemia, which involve entirely different pathophysiological processes and treatment goals.
