Fentanyl is a highly potent synthetic opioid of the piperidine family, used primarily as pain medication. It is 50 to 100 times more potent than morphine. Its primary clinical use is in pain management for cancer patients and those recovering from surgery. Fentanyl is also used as a sedative for intubated patients. Fentanyl has a short duration of action. Fentanyl works by activating μ-opioid receptors. Brand names include Actiq, Duragesic, and Sublimaze, among others.
