An expectorant (from the Latin expectorare, to expel or banish) works by signaling the body to increase the amount or hydration of secretions, resulting in more, yet clearer, secretions and lubricating the irritated respiratory tract.

Guaifenesin might act as an expectorant by increasing the volume and reducing the viscosity of secretions in the trachea and bronchi via stimulation of the gastric mucosa. . This stimulation leads to an increased parasympathetic activity in the respiratory tract via the so-called gastro-pulmonary reflex, although some in vitro studies suggested that it might also act directly on the ...
