Indications & Uses

Pharmacology

Erdosteine is a prodrug, which means the body has to change it before it works. It is metabolised into N-thiodiglycolyl-homocysteine, and this process forms free thiol groups. These groups open the disulphide bonds of the bronchial mucoproteins, so the mucus and purulent sputum become less viscous.

Erdosteine also works against the local formation of free radicals. It inhibits the activity of the elastase enzyme as well, and it reduces the adhesion of bacteria to epithelial cells.
