Viminol is an opioid analgesic developed by the company Zambon. It is marketed under tradename Dividol for the treatment of pain due to various causes, including the treatment of pain due to osteoarthritis, neuritic pain, vascular pain, visceral pain, neoplastic pain, and pain due to other sources. In vivo studies demonstrated that the analgesic effects of viminol depend on the stereo configuration: the R,R-enantiomer exhibit agonistic activity, while the S,S-enantiomer produce the opposite effect.
