Expectorants are primarily used to do what?

Expectorants are primarily used to facilitate mucus clearance from the respiratory tract. They work by thinning and loosening mucus in the airways, making it easier for individuals to cough it up. This process helps to clear congestion and improves airflow in the lungs, which is particularly beneficial in cases of respiratory conditions associated with excessive mucus production, such as bronchitis or pneumonia. By promoting mucus clearance, expectorants play a crucial role in supporting respiratory health and enhancing the efficiency of the clearing mechanisms of the lungs.
