Description
Curator's Comment: description was created based on several sources, including, http://www.ncbi.nlm.nih.gov/pubmed/18046899, https://www.old.health.gov.il/units/pharmacy/trufot/alonim/ERDOTIN_dr_1322978767512.pdf

Erdosteine is an antioxidant compound developed by Edmond Pharma and approved in Europe for the treatment of chronic bronchitis and COPD. Erdosteine has two thiol groups and is believed to act as a free radicals scavenger (through the formation of the active metabolite I, N-thiodiglycolylhomocysteine). Also the drug effect may be due to the inhibition of the activity of elastase enzyme and its interaction with mucosa. The drug got Orphan Drug designation by FDA for the treatment of bronchiectasis.
