Erdosteine is a mucolytic. Specifically it is a thiol derivative developed for the treatment of chronic obstructive bronchitis including acute infective exacerbation of chronic bronchitis. Erdosteine contains two blocked sulfhydryl groups which are released following first-pass metabolism. The three active metabolites exhibit mucolytic and free radical scavenging activity. Erdosteine modulates mucus production and viscosity and increases mucociliary transport thereby improving expectoration.
