Tyloxapol is a nonionic liquid polymer of the alkyl aryl polyether alcohol type. It is used as a surfactant to aid liquefaction and removal of mucopurulent[citation needed] (containing mucus and pus) bronchopulmonary secretions,[1][2] administered by inhalation through a nebulizer[3] or with a stream of oxygen.

With intraperitoneal injection, tyloxapol also blocks plasma lipolytic activity, and thus the breakdown of triglyceride-rich lipoproteins. This mechanism is used to induce experimental hyperlipidemia in animals.[4]

Tyloxapol is the main active ingredient of the medical device Tacholiquin. Tacholiquin is an expectorant designated for inhalation and instillation reaching the upper and lower airways. Other brand names of pharmaceutical products containing Tyloxapol are Exosurf and Alevaire.
