Official title
Methadone for Enhanced Postoperative Analgesia in Intermediate-Risk Noncardiac Surgery: A Multicentre Randomized Controlled Trial (MELODY Trial)
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Postoperative pain control remains suboptimal for a large proportion of surgical patients and is frequently associated with slower recovery and higher reliance on opioids after surgery. Current intraoperative analgesic approaches predominantly use short-acting opioids, whose rapid pharmacokinetics can lead to variable drug exposure and inconsistent control of nociceptive stimuli. Methadone has a different pharmacologic profile, combining prolonged μ-opioid receptor activity with N-methyl-D-aspartate receptor antagonism, allowing sustained analgesia following a single intraoperative administration and potentially enhancing postoperative recovery. The MELODY trial is a multicentre, randomized, patient-blinded clinical study designed to compare a single intravenous dose of methadone given at induction with conventional short-acting opioid-based anesthesia in adults undergoing intermediate-risk noncardiac surgery. The primary aim is to evaluate whether this strategy leads to improved quality of recovery on the first postoperative day.
