Ciramadol (WY-15,705) is an opioid analgesic that was developed in the late 1970s^[1] and is related to phencyclidine, tramadol, tapentadol and venlafaxine.^[2] It is a mixed agonist-antagonist for the μ-opioid receptor with relatively low abuse potential^[3] and a ceiling on respiratory depression^[4] which makes it a relatively safe drug. It has a slightly higher potency and effectiveness as an analgesic than codeine,^[5] but is weaker than morphine.^[6] Other side effects include sedation and nausea but these are generally less severe than with other similar drugs.^[7]
