Tacholiquin 1% solution contains tyloxapol, which is a non-ionic wetting agent. Tyloxapol has a secretolytic (expectorant) effect and lowers the surface tension. As a result, after application of Tacholiquin 1% solution, mucus and secretions on the mucous membranes are liquefied and better dissolvable, even though it does not affect the physiological conditions. Tacholiquin 1% solution also contains 5% glycerine to stabilize the droplet spectrum of the inhalation solution.
