NCT ID NCT02468128

First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This study tested a single injection of a long-acting painkiller called SDE in 221 adults recovering from hemorrhoid surgery. Half received the drug and half a placebo. Researchers measured pain levels and how much extra pain medicine was needed over 48 hours. The goal was to see if SDE provides better pain control after surgery.
