Dipipanone, sold under the brand names of Pipadone and Diconal[3] is a strong opioid analgesic drug, used for acute pain by mouth (PO) for adults.

[4] The main preparation of the drug commercially available is mixed with cyclizine (Diconal, Wellconal) which has the advantage of reducing nausea, vomiting and histamine release associated with strong opioid therapy.

As of November 2011 Amdipharm stopped making the Diconal brand tablets for the UK due to undisclosed commercial reasons.

Dipipanone is now unavailable in most countries of the world either by laws prohibiting its medicinal use as in the United States or by falling out of production as more modern analgesics took its market share.

Dipipanone is a Schedule I controlled substance in the United States; it has been assigned the ACSCN of 9622 and since 2013 had an annual manufacturing quota of 5 grams.
