Metabolite Identification
Common NameLevorphanol
DescriptionLevorphanol, also known as levo dromoran or dea no. 9220, belongs to the class of organic compounds known as morphinans. These are polycyclic compounds with a four-ring skeleton with three condensed six-member rings forming a partially hydrogenated phenanthrene moiety, one of which is aromatic while the two others are alicyclic. Levorphanol is a drug which is used for the management of moderate to severe pain or as a preoperative medication where an opioid analgesic is appropriate. It is a narcotic analgesic that may be habit-forming. Like other mu-agonist opioids it is believed to act at receptors in the periventricular and periaqueductal gray matter in both the brain and spinal cord to alter the transmission and perception of pain. The respiratory and cardiac status of the patient should be continuously monitored and appropriate supportive measures instituted, such as oxygen, intravenous fluids and/or vasopressors, if required. Levorphanol is a very strong basic compound (based on its pKa). In humans, levorphanol is involved in levorphanol action pathway. Levorphanol is similar to morphine in its actions, however it is up to 8 times more potent than morphine. Levorphanol is a potentially toxic compound. It is nearly as effective orally as by injection.
