The primary action of expectorants is to increase respiratory secretions, which lubricate and help liquefy mucus. The expectorants include salts (ammonium chloride and potassium citrate), and guaifenesin. Guaifenesin (Mucinex) is available over the counter and is the most frequently used expectorant for the relief of an unproductive cough.
