Answer

Expectorants

One of the hallmarks of bronchiectasis is a chronic, thick, viscid sputum production. In bronchiectasis, it is extremely difficult for the body's natural mucociliary clearance mechanisms to adequately clear the sputum produced. Although definitive evidence is lacking, expectorants are expected to increase respiratory tract fluid secretions and to help loosen phlegm and bronchial secretions.

By reducing the viscosity of secretions, expectorants increase the efficacy of the mucociliary clearance system. Expectorants are often marketed in combination with decongestants, which may provide some patients additional relief.

Guaifenesin (Mucinex)

The product contains 600 mg of guaifenesin in a sustained-release formulation intended for oral administration. It increases respiratory tract fluid secretions and helps to loosen phlegm and bronchial secretions. Humibid LA and guaifenesin are indicated for patients with bronchiectasis complicated by tenacious mucus and/or mucous plugs.
