New study tests safer pain relief for oral cancer patients
NCT ID NCT07606638
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study compares two pain management strategies for adults with oral cancer who have moderate to severe pain. One group receives the opioid tramadol, while the other gets a combination of pregabalin and naproxen sodium. Over 7 days, researchers measure pain reduction, side effects, and patient satisfaction to see which approach works better and is safer.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- tramadol (opioid) and pregabalin plus naproxen sodium
- What this could lead to
- If this trial succeeds, it could show that a non-opioid combination (pregabalin + naproxen) works as well as or better than tramadol for oral cancer pain, offering a safer alternative with fewer side effects.
- What could go wrong
- This is a small, single-center study with only 98 participants, so results may not apply to everyone. The short 7-day treatment period doesn't show long-term effects or risks like dependence or tolerance.
