Pharmacology
Levorphanol is a potent synthetic opioid analgesic indicated for the management of moderate to severe pain or as a preoperative medication where an opioid analgesic is appropriate. Levorphanol is similar to morphine in its actions, however it is up to 8 times more potent than morphine. Levorphanol produces a degree of respiratory depression similar to that produced by morphine at equianalgesic doses, and like many mu-opioid drugs, levorphanol produces euphoria or has a positive effect on mood in many individuals.
