Dipipanone hydrochloride is an opioid painkiller. In combination with cyclizine hydrochloride, it is marketed as Diconal, indicated for relief of moderate to severe pain.

Chemically, dipipanone belongs to the class of opiates called the 3-diphenyl heptanones. It closely resembles methadone, the only structural difference being the N,N-dimethyl moety of methadone being replaced with a piperidine ring. It's usage is now officially discouraged because of the abuse risk. The combination with cyclizine lends a very strong rush if the drug is injected. During the late 1970s to early 1980s in the UK, a whole spate of deaths were blamed on this preparation. Cyclizine itself was removed from the shelves of pharmacists because opiate addicts were crushing & mixing the drug with methadone. Injecting cyclizine when an addict has taken methadone orally still gives the user a BIG rush.
