Ciprefadol is an opioid analgesic that is an isoquinoline derivative most closely related to cyclazocine and picenadol,[1] with a number of other related compounds known.[2][3][4][5] Ciprefadol is a mixed agonist–antagonist at μ-opioid receptors and can partly block the effects of morphine at low doses, though at higher doses it acts more like a full agonist. It is also a potent κ-opioid agonist, unlike the corresponding N-methyl and N-phenethyl derivatives which are reasonably μ-selective agonists.[6]
