Fedotozine (INN; Jo-1196) is an opioid drug of the arylacetamide series which acts as a peripherally-specific, selective κ1-opioid receptor agonist with preference for the κ1A subtype.[1] It was under investigation for the treatment of gastrointestinal conditions like irritable bowel syndrome and functional dyspepsia and made it to phase III clinical trials,[1][2][3] but ultimately development was discontinued and it was never marketed.
