regimen during an operation. Because of its extremely high potency, it is often used in surgery and post-operative pain management for patients that are heavily opioid dependent/opioid tolerant because of long term opiate use for chronic pain or illicit opiate use. Currently sufentanil is the most potent opioid painkiller available for use in humans. Although more potent narcotic pain medications do exist, all medications stronger than sufentanil are approved for veterinary use only. It is also used in surgery and post operative pain control in patients that are taking high dose

for chronic pain because it is the only opioid that has a potency and binding affinity strong enough to displace buprenorphine from the opioid receptors in the central nervous system and provide analgesia.

for use in battlefield settings where intravenous (IV) treatments may not be readily available. The decision to approve this new potent synthetic opioid came under criticism from politicians and from the chair of the FDA advisory committee, who fear that the tablets will be easily diverted to the illegal drug market.
