Oxymorphone, sold under the brand names Numorphan among others, is a powerful semi-synthetic opioid analgesic (painkiller) developed in Germany in 1914. Pain relief after injection begins after about 5–10 minutes and 15–30 minutes after rectal administration, and lasts about 3–4 hours for immediate-release tablets and 12 hours for extended-release tablets.
