Guaiphenesin

Description

An expectorant that also has some muscle relaxing action. It is used in many cough preparations. [PubChem]

Indication

Used to assist the expectoration of phlegm from the airways in acute respiratory tract infections.

Mechanism of Action

Guaifenesin may act as an irritant to gastric vagal receptors, and recruit efferent parasympathetic reflexes that cause glandular exocytosis of a less viscous mucus mixture. Cough may be provoked. This combination may flush tenacious, congealed mucopurulent material from obstructed small airways and lead to a temporary improvement in dyspnea or the work of breathing.
