Cebranopadol (trans‐6′‐fluoro‐4′,9′‐dihydro‐N,N‐dimethyl‐4‐phenyl‐spiro[cyclohexane‐1,1′(3′H)‐pyrano[3,4‐b]indol]‐4‐amine) is a novel analgesic nociceptin/orphanin FQ opioid peptide (NOP) and classical opioid receptor (MOP, DOP, and KOP) agonist with highly efficacious and potent activity in a broad range of rodent models of nociceptive, inflammatory, and neuropathic pain as well as limited opioid‐type side effects such as respiratory depression. This evidence concerns the gene PNOC and respiratory depression.
