Could common painkillers boost opioid effectiveness for cancer patients?

NCT ID NCT07682558

First seen Jul 06, 2026 · Last updated Jul 08, 2026 · Updated 2 times

Summary

This trial investigates whether adding the non-opioid drugs metamizole (dipyrone) or ibuprofen to standard opioid therapy provides better pain relief for people with cancer-related pain. About 318 adults with advanced cancer and moderate to severe pain will receive either metamizole, ibuprofen, or a placebo alongside their opioid treatment. The study measures changes in average daily pain over one week to see if the combination approach is more effective than opioids alone.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance
Metamizole (dipyrone) and ibuprofen
What this could lead to
If it works, this could provide a safer, more effective way to manage cancer pain by combining non-opioid drugs with opioids.
What could go wrong
This is a Phase 3 trial, but results may not apply to all cancer patients. Side effects from metamizole or ibuprofen are possible, and the drugs may not prove more effective than placebo.
