Levorphanol, brand name Levo-Dromoran, is an opioid medication used to treat moderate to severe pain. Levorphanol is indicated for the management of moderate to severe pain where an opioid analgesic is appropriate. It is a potent synthetic opioid mu-receptor agonist similar in action to morphine. Like other opioid mu-receptor agonists, it is believed to act at receptors in both the brain and spinal cord to alter the transmission and perception of pain. The onset and peak analgesic effects following administration of levorphanol are similar to morphine when administered at equal analgesic doses. Levorphanol produces a degree of respiratory depression similar to that produced by morphine at equal analgesic doses, and like many opioid mu-receptor agonists, levorphanol produces euphoria or has a positive effect on mood in many individuals.

Originator

Curator's Comment: Levorphanol was initially synthesized in Germany in 1946

Sample Use Guides

Usual Adult Dose for Light Sedation Premedication for Anesthesia: 1 to 2 mg IM or subcutaneously, administered 60 to 90 minutes before surgery. Older or debilitated patients usually require less drug. Two mg of levorphanol is approximately equivalent to 10 to 15 mg of morphine or 100 mg of meperidine. Usual Adult Dose for Pain IV: 1 mg every 3 to 6 hours as needed. IM or subcutaneous: 1 to 2 mg every 6 to 8 hours as needed. Oral: 2 mg every 6 to 8 hours as needed. May be increased to 3 mg every 6 to 8 hours.
