Medical Definition of Expectorant. Expectorant: A medication that helps bring up mucus and other material from the lungs, bronchi, and trachea. An example of an expectorant is guaifenesin, which promotes drainage of mucus from the lungs by thinning the mucus, and also lubricates the irritated respiratory tract. Search MedTerms:
Guaifenesin is an expectorant [from the Latin expectorare, to expel from the chest] that tries to increase hydration of your secretions and get the mucus (i.e., symptoms of congestion) out of your chest. The idea is that the more lubricated the respiratory tract, the easier it is for the lungs to expel the mucus.
