Definitions for oxymorphone
This page provides all possible meanings and translations of the word oxymorphone
A particular narcotic painkiller.
Oxymorphone or 14-Hydroxydihydromorphinone is a powerful semi-synthetic opioid analgesic first developed in Germany in 1914, patented in the USA by Endo Pharmaceuticals in 1955 and introduced to the United States market in January 1959 and other countries around the same time. It was designed to have less incidence of side effects than morphine and heroin. The brand name Numorphan is derived by analogy to the Nucodan name for an oxycodone product as well as Paramorphan/Paramorfan for dihydromorphine and Paracodin. The only commercially available salt of oxymorphone in most of the world at this time is the hydrochloride, which has a free base conversion ratio of 0.891. In some countries, hydromorphinol is distributed under the trade names Numorphan and Numorphan Oral. This is a relatively rare exception and the two drugs, whilst both being strong opioid analgesics, are notably different from one another. Oxymorphone is administered as its hydrochloride salt via injection, or suppository; typically in dosages of 1 mg to 5 mg. Endo has been the major distributor of oxymorphone throughout the world and currently markets oxymorphone in the United States and elsewhere as Opana and Opana ER.

An opioid analgesic with actions and uses similar to those of MORPHINE, apart from an absence of cough suppressant activity. It is used in the treatment of moderate to severe pain, including pain in obstetrics. It may also be used as an adjunct to anesthesia. (From Martindale, The Extra Pharmacopoeia, 30th ed, p1092)
