Oxymorphone
From The Art and Popular Culture Encyclopedia
The principal adverse effects of oxymorphone are similar to other opioids with constipation, nausea, vomiting, dizziness, dry mouth and drowsiness being the most common adverse effects. This drug is highly addictive as with other opioids and can lead to chemical dependence and withdrawal. In common with other opioids, oxymorphone overdosage is characterized by respiratory depression, sleepiness progressing to stupor or coma, skeletal muscle weakness, cold and clammy skin, and sometimes slow heart rate and low blood pressure. In a severe case of overdose, apnea, circulatory collapse, cardiac arrest and death can occur. |

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.
