WebIn vitro binding to a battery of 43 central nervous system receptors showed it to be a high-affinity μ-opioid receptor (MOR) and κ-opioid receptor (KOR) ligand (60 nM and 34 nM, respectively). AP01 also had a 4 nM affinity for the serotonin transporter (SERT), which is a higher level of potency at this receptor than most other opioids. WebAs a fentanyl analog, sufentanil is a highly lipophilic synthetic piperidine derivative opioid that has high affinity for μ-opioid receptors and is suitable for postoperative pain control because it has no active metabolites and shows a higher therapeutic index and lower frequency of respiratory suppression than fentanyl [ 4 ].
