Summary

This study tests whether giving the pain drug Anrikefon before or during gallbladder surgery works better for reducing pain and helping recovery. 274 adults having laparoscopic gallbladder removal will receive the drug either 15 minutes before anesthesia or right after the gallbladder is removed. Researchers will track pain levels and recovery quality over 24 hours to find the best timing.

What this could mean

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

Active substance
Anrikefon
What this could lead to
If successful, this could show the best timing for Anrikefon to reduce pain after gallbladder surgery and improve recovery.
What could go wrong
This is an early-stage study with no phase, so results may not confirm benefit. The drug's effect on pain is still being explored, and individual responses may vary.

This is an AI summary of the original study and may miss details. Read our disclaimer.
