sufentanil citrate

The citrate salt form of sufentanil, a synthetic congener of fentanyl and related to the phenylpieridines, with analgesic property. Sufentanil citrate binds to and activates the mu-opioid receptor, thereby producing analgesia, respiratory depression, miosis, reduced gastrointestinal motility, and euphoria. In addition, this agent has a more rapid onset of action and shorter duration of action compared to fentanyl.
