Expectorants such as ambroxol hydrochloride and bromhexine can also be used. 3. Bronchodilators: Patients who already have obstructive ventilation dysfunction can use bronchodilators such as salmeterol to improve airflow limitation. 4. Hemostatic drugs: bronchial dilatation with blood in sputum, bleeding is not much can be oral carbachol and other hemostatic drugs.
