Background: Since the introduction of laparoscopic surgeries, postoperative pain has been generally reduced. However, it can still peak, especially during the early postoperative period and becomes the main cause of overnight hospital stay and prolonged convalescence after this day-case surgical procedure. Thus, optimizing postoperative pain relief, not only to sub-serve reduction of its intensity but to also enhance the recovery and shorten length of stay became the broader target of multimodal pain control regimens nowadays. That is why; searching for a drug that would be effective in reducing pain, safe from major adverse effects and can meanwhile possess an opioid-sparing potentiality would be a merit so as to improve the success rate of ambulatory day-care surgeries. Objective: To study the analgesic effects of preemptive single oral dose of paracetamol, celecoxib and pregabalin in patients undergoing gynecological laparoscope. Method: Preoperative evaluation, preparation and premedication was assessment, and routine laboratory investigations was done. Postoperative pain, Level of Sedation was measured. Results: There was statistical significant difference between the three groups regarding VAS. There was statistical significant difference between the three groups regarding the total pethidine consumption. Regarding postoperative level of sedation, blood glucose there was no statistical significant difference between the three groups. Conclusion: Oral pregabalin in a dose of 150 mg 2 hour before surgery, is significantly attenuating pain intensity and total meperidine consumption during the first 6 hours postoperatively.
