What is a primary reason for the use of mucolytic agents?

Mucolytic agents are primarily used to thin and loosen mucus in the respiratory tract. This is crucial for patients suffering from conditions characterized by thick mucus, such as chronic obstructive pulmonary disease (COPD) or cystic fibrosis. By reducing the viscosity of mucus, mucolytics facilitate easier expectoration, helping to clear the airways and improve breathing. This mechanism enhances the ability to manage respiratory conditions effectively, as it helps prevent blockages in the airways and reduces the risk of infections that can arise from stagnant mucus.
