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 (containing mucus and pus) bronchopulmonary secretions, administered by inhalation through a nebulizer or with a stream of oxygen. 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 (containing mucus and pus) bronchopulmonary secretions, administered by inhalation through a nebulizer 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.
