Summary

This study compared a single dose of gabapentin (600 mg) versus diclofenac sodium (100 mg) given one hour before major abdominal surgery to see which provides better pain relief afterward. A total of 240 adults aged 18 to 60 took part. Pain was measured using a standard pain scale, and effective relief was defined as a score of 3 or less without needing extra pain medicine.

What this could mean

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

Active substance
gabapentin and diclofenac sodium
What this could lead to
If effective, this could help doctors choose a better single-dose painkiller for patients before major abdominal surgery.
What could go wrong
This is a small, completed trial with no phase designation, so results may not apply to all surgeries or patients. Pain relief was measured only in the short term.
