Summary
Sufentanil, also known as sufentanyl and by the brand name Sufenta, is an extremely potent synthetic anilidopiperidine opioid analgesic. Sufentanil has a rapid onset and short mechanism and is used medically as an analgesic in surgical procedures or for the management of post-operative pain. Sufentanil is roughly 500 to 1,000 times more potent than pharmaceutical grade morphine and is approximately 10 times more potent than pharmaceutical grade fentanyl.
