Mechanism of action

Fentanyl activates mu opioid receptors throughout the brain and spinal cord, inhibiting pain signal transmission and producing profound analgesia and sedation suitable for general anesthesia induction and maintenance. It is approximately 50–100 times more potent than morphine and has a rapid onset and relatively short duration of action, making it ideal for perioperative use.
