Jan 14Lancet Neurology 2013: 12 (12); 1141-50. This multicentre European study consisted of a 12-week randomised, double-blind, placebo-controlled trial and 40-week open-label extension phase. Patients had symptoms for ≥6 months and an IRLS Study Group severity rating scale sum score of ≥15. Study drug was oxycodone 5mg, naloxone 2.5mg, twice per day, up-titrated as necessary to a maximum of 40/20mg twice daily. The primary outcome was mean change in severity of symptoms based on the IRLS Study Group severity rating scale sum score (SRSSS) at 12 weeks. 306 subjects were randomly assigned and 276 included in the primary analysis. 197 patients participated in the open-label extension. Mean SRSSS at randomisation was 31.6; mean change after 12 weeks was −16.5 in the oxycodone—naloxone group vs −9•4 in the placebo group (mean difference 8•15, 95% CI 5•46—10•85; p
