Picenadol (LY-150720) is a 4-phenylpiperidine derivative that is an opioid analgesic drug.

Picenadol is an effective analgesic with similar efficacy to pethidine (meperidine). It has been investigated for some applications such as obstetrics[1] and dentistry,[2] but never commercialised.

It is unusual in that one enantiomer is a pure μ-opioid agonist, while the other is an antagonist.[3] The (3R,4R) isomer is the agonist, while (3S,4S) is antagonist.[4] This means that the racemic mix of the two enantiomers is a mixed agonist-antagonist, with relatively low abuse potential, and little of the κ-opioid activity that tends to cause problems with other opioid mixed agonist-antagonists such as pentazocine.[5]
