Effect of Low-dose Pregabalin Retard (82.5 mg) Versus Standard-dose Pregabalin Retard (165 mg) on Postoperative Pain and Opioid Consumption After Elective Laparoscopic Abdominal Surgery

The goal of this clinical trial is to detect whether pregabalin retard (82.5 mg or 165 mg) improves analgesia after elective laparoscopic abdominal surgery in adults. It will also evaluate the safety of both doses. The main questions it aims to answer are: Does the higher dose (165 mg) reduce the total amount of opioids needed in the first 24 hours after surgery compared to the lower dose (82.5 mg)? Do the pain scores differ between the two doses? Are there differences in side effects between the two doses? Researchers will compare two different doses of pregabalin retard to determine which provides better pain control with fewer side effects. Participants will: Take one dose of pregabalin retard (82.5 mg or 165 mg) before surgery Receive standard anesthesia and multimodal pain treatment Have their pain levels and opioid use monitored for 24 hours after surgery Be assessed for side effects such as dizziness, nausea, or sedation
