Ciramadol (WY-15705) is an opioid analgesic that was developed in the late 1970s and is related to phencyclidine tramadol tapentadol and venlafaxine. It is a mixed agonist-antagonist for the μ-opioid receptor with relatively low abuse potential and a ceiling on respiratory depression which makes it a relatively safe drug. It has a slightly higher potency and effectiveness as an analgesic than codeine but is weaker than morphine.
