The therapy that focuses on improving the expectoration of bronchopulmonary secretions in individuals with chronic respiratory conditions is mucolytics. Mucolytics are agents that work to thin and loosen mucus in the airways, which facilitates its clearance from the respiratory system. This is particularly beneficial for patients suffering from chronic bronchitis, cystic fibrosis, or other pulmonary conditions characterized by excessive or thickened secretions.

Mucolytics help in reducing the viscosity of the mucus, making it easier to cough up; this not only improves airflow but also helps in preventing infections that can arise from retained secretions. By enhancing expectoration, mucolytics play a significant role in managing chronic respiratory disorders effectively.

Other therapies, such as inhaled corticosteroids and bronchodilators, serve different purposes—corticosteroids primarily reduce inflammation, while bronchodilators work to open the airways. Diuretics are used to manage fluid retention and are not directly involved in mucous management. Thus, mucolytics are specifically designed for the purpose of aiding mucus clearance, making them the correct choice in this context.
