Expectorant cough, phlegm cough for chronic bronchitis, bronchiectasis and other illnesses
Guaifenesin or guaiphenesin (former BAN), also glyceryl guaiacolate,is an expectorant drugsold
over the counter and usually taken orally to assist the bringing up (expectoration) of phlegm from
the airways in acute respiratory tract infectiion.
Effect and mechanism of action
Guaifenesin is thought to act as an expectorant by increasing the volume and reducing the viscosity of secretions in the trachea and bronchi. It also stimulates the flow of respiratory tract secretions, allowing ciliary movement to carry the loosened secretions upward toward the pharynx.Thus, it may increase the efficiency of the cough reflex and facilitate removal of the secretions; however, objective evidence for this is limited and conflicting. |
