Introduction: Pain, an inherently subjective experience, plays a pivotal role in the body's defence mechanism by signalling tissue damage or potential harm. Thus, optimal postoperative pain management is a cornerstone of modern surgical practice, essential for improving recovery outcomes and overall patient well-being., Methods: In this study, a total of 60 patients were randomly assigned to two groups of 30 each: Group C (clonidine) and Group G (gabapentin). Group C received oral clonidine 100 mcg and Group G received oral gabapentin 600 mg one hour prior to the subarachnoid block. Duration of sensory and motor block, hemodynamic parameters, Visual Analog Scale (VAS) scores, time to rescue analgesia and any side effect of both drugs were assessed in both groups., Results: The duration of motor and sensory blockade, as well as intraoperative hemodynamics and respiratory rates, were comparable between the two groups. Group G exhibited significantly lower VAS scores from 150 minutes postoperatively up to 12 hours (p < 0.001). Additionally, Group G experienced longer duration of postoperative analgesia (16.8±3.9 hours) compared to Group C (9.27±1.7 hours). About 26.6% of the patients in Group C and 6.7% of the patients in Group G presented with postoperative nausea and vomiting (PONV)., Conclusion: Oral gabapentin at a dosage of 600 mg demonstrates superior efficacy as a premedication compared to oral clonidine 100 mcg for patients undergoing lower abdominal and lower limb surgeries under spinal anesthesia. Group G demonstrated extended postoperative analgesia, lower VAS scores, and a reduced incidence of PONV, indicating its superiority over clonidine as an analgesic adjunct., Competing Interests: Human subjects: Consent was obtained or waived by all participants in this study.
