Some cheap alternatives, such as methadone or tramadol, may work for cancer pain but have not been properly tested in these settings.","summary":"Morphine stock-outs are common in LMICs, leaving patients without analgesia. Methadone is inexpensive, long-acting, and effective for cancer pain but needs careful titration; tramadol is widely available but weaker and not internationally controlled, which affects supply differently. Pragmatic trials of protocolised methadone or tramadol-based regimens delivered by nurses in settings with unreliable morphine would establish safe fallback options and could inform essential medicines lists.","asOf":"2026-09-08","links":[{"label":"Bottleneck evidence (Pain relief and palliative care are unavailable to most): WHO fact sheet, Palliative care","url":"https://www.who.int/news-room/fact-sheets/detail/palliative-care"}],"tags":[],"related":["idea-acc-chemo-stockout-early-warning"],"cancers":[],"sections":[],"technologies":[],"targets":[],"drugs":[],"companies":[],"institutions":[],"pathways":[],"terms":[],"trials":[],"people":[],"bottlenecks":["b-palliative","b-global-access"],"keyPapers":[],"journals":[],"dependsOn":[],"notes":[],"hypothesis":"A protocolised methadone regimen delivered by trained nurses will achieve pain control non-inferior to oral morphine in patients with moderate to severe cancer pain, with acceptable safety.","rationale":"Methadone is already used for cancer pain by specialists in high-income countries and is on the WHO essential medicines list; the question is safe delivery by non-specialists.","test":"A randomised non-inferiority trial in three LMIC centres comparing methadone protocol with morphine on pain scores at two weeks, with sedation and QT monitoring as safety endpoints.","maturity":"speculative","actor":"research","cost":"medium","horizonYears":4},"route":"/ideas/idea-acc-methadone-and-alternatives-where-morphine-fails/","neighbours":{"idea":[{"id":"idea-acc-chemo-stockout-early-warning","kind":"idea","name":"A live stock-out map for essential chemotherapy drugs","route":"/ideas/idea-acc-chemo-stockout-early-warning/"}],"bottleneck":[{"id":"b-global-access","kind":"bottleneck","name":"Most of the world has almost no cancer care","route":"/bottlenecks/b-global-access/"},{"id":"b-palliative","kind":"bottleneck","name":"Pain relief and palliative care are unavailable to most","route":"/bottlenecks/b-palliative/"}]}}
