Preoperative Pregabalin vs Gabapentin in Elderly Undergoing Surgry,Controlled Trial

Several studies have evaluated the efficacy of pregabalin in reducing preoperative anxiety, with inconsistent results. Similarly, inconclusive results have been reported regarding gabapentin and its effects in reducing preoperative anxiety. A previous study reported that a single dose of gabapentin or pregabalin administered 60 minutes before surgery in adults under general anesthesia was effective in reducing acute preoperative anxiety and elevated levels of sedation before and after surgery, with pregabalin having better anxiolytic and sedative effects than gabapentin. However, no previous studies have compared the efficacy of preoperative pregabalin or gabapentin as premedication to reduce intraoperative anxiety and induce sedation in geriatric patients undergoing major surgery with regional anesthesia
