First seen May 12, 2026 · Last updated May 12, 2026

Summary

This study tested two drugs, oxycodone (a strong painkiller) and levodopa (a Parkinson's medication), against a placebo to see if they could reduce nerve pain caused by Parkinson's disease. 67 people with Parkinson's and chronic nerve pain took one of the three treatments for 8 weeks, in addition to their usual medications. The main goal was to see if average pain levels decreased more with the active drugs than with the placebo.
