Montelukast is primarily indicated for the treatment of what condition?

Montelukast is primarily indicated for the treatment of asthma due to its role as a leukotriene receptor antagonist. It works by inhibiting the action of leukotrienes, which are inflammatory chemicals in the body that contribute to asthma symptoms such as bronchoconstriction, increased mucus production, and airway inflammation. By blocking these receptors, montelukast helps to prevent and control asthma symptoms, making it a critical part of management for individuals with this respiratory condition.

In addition to asthma, montelukast is also used in the management of allergic rhinitis, but its primary indication remains asthma, where it aids in improving lung function and reducing the frequency of asthma attacks.
