First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
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.
