The past is prologue: Reconceptualizing methadone and buprenorphine for post-operative pain.

Opioids remain a central element of perioperative pain management despite increased utilization of multimodal adjuvant strategies intended to reduce their use. Contemporary use of methadone and buprenorphine, both conceived as opioid analgesics, is dominated by their essential roles in the treatment of opioid use disorder. Compared to usual care opioids, however, they provide improved post-operative pain control while reducing analgesic requirements. These findings argue for their expanded role within perioperative multimodal analgesia strategies.
