Our objective in a randomized, multicenter, double-blind, parallel-group, placebo- and active-controlled study was to evaluate and compare the analgesic effectiveness of single intravenous (IV) doses of parecoxib sodium 20 and 40 mg, morphine 4 mg, and ketorolac 30 mg in the postsurgical orthopedic pain model. After undergoing unilateral total knee replacement surgery, 208 healthy adult patients were randomized to receive placebo or a study drug within 6 hours of discontinuation of patient-controlled analgesia on postoperative day 1. Onset of analgesia was similarly rapid with IV parecoxib sodium 40 mg, morphine, and ketorolac. Level and duration of analgesia were significantly superior with parecoxib sodium than with morphine and were similar for parecoxib sodium and ketorolac. Parecoxib sodium was safe and well tolerated. In conclusion, IV parecoxib sodium 40 mg is as effective as ketorolac 30 mg and is more effective than morphine 4 mg and therefore has potential widespread utility in acute postoperative pain management.

Parecoxib sodium, the injectable prodrug of valdecoxib, is a cyclooxygenase-2-specific inhibitor that is effective in the treatment of postoperative pain. In this randomized, double-blind, placebo-controlled study, we compared the efficacy of a single dose of parecoxib sodium 40 mg IM with single doses of morphine 6 and 12 mg IM in treating postoperative pain after gynecologic surgery requiring a laparotomy incision. By nearly all efficacy measures (including total pain relief and patient's global evaluation of study medication), parecoxib sodium 40 mg IM demonstrated pain relief and a decrease in pain intensity that was statistically similar to that with morphine 12 mg IM and superior to that with morphine 6 mg IM. Parecoxib sodium 40 mg IM-treated patients also demonstrated a longer time to use of rescue medication than patients treated with both morphine doses, and this dose provided sustained pain relief over the 12-h study period. The incidence of adverse events in the active treatment groups was similar to that observed with placebo. Parecoxib sodium, 40 mg IM, has been shown to be as effective as clinically relevant doses of morphine in patients after gynecologic laparotomy surgery.

Our objective is to analyze and observe the different administration routes of parecoxib sodium pretreatment on the behavioral improvement of rats with neuropathic pain to provide the preclinical data of parecoxib sodium on neuropathic pain treatment. 30 SD rats were randomly divided into five groups, including model group, sham operation group, intrathecal injection group (IT group), intraperitoneal injection group (IP group), and perineural infiltration group (PI group). The rats in model group and three parecoxib sodium pretreatment groups received spinal nerve ligation (SNL). Heat pain test and 50 % paw mechanical withdrawal threshold test (50 % PMWT) were use to assess the responses after parecoxib sodium pretreatment. 50 % PMWT results of right foot in five groups had no statistical difference (P > 0.05); 50 % PMWT results of left and right feet in three parecoxib sodium pretreatment groups were obviously higher than SNL group at different time points, which was statistically different (P < 0.05); in comparison with three pretreatment groups, the data of left foot in IT group were obviously higher than PI group and IP group, and the comparison among three groups had significant difference (P < 0.05). However, the data of right foot had no significant difference among three groups (P > 0.05). Paw thermal withdrawal latency (PTWL) results of left and right feet in five groups had no significant difference before surgery (P > 0.05); after the establishment of neuropathic model, PTWL results in five groups were significantly decreased; however, PTWL results of left and right feet at 3 days after surgery in IT group were significantly higher than the two other pretreatment groups (P < 0.05); PTWL results of left and right feet at 7 and 14 days after surgery had no significant difference. Parecoxib sodium pretreatment can effectively improve the behaviors caused by neuropathic pain, and intrathecal injection is the most effective route of administration.

BACKGROUND This study aimed to investigate the effectiveness of perioperative parecoxib sodium combined with transversus abdominis plane (TAP) block on postoperative pain management following hepatectomy in patients with hepatocellular carcinoma (HCC). MATERIAL AND METHODS One hundred patients with HCC who underwent hepatectomy were randomized into a study group (n=51) and a control group (n=49). The study group received 40 mg of parecoxib sodium 30 minutes before anesthetic induction, and 150 mg of 0.375% ropivacaine with 5 mg dexamethasone as TAP inhibitors, before closing the abdominal incision. The control group received 40 mg of placebo 30 minutes before anesthetic induction, without TAP block. Postoperatively, all patients received patient-controlled intravenous analgesia (PCIA) and evaluation with subjective visual analog scale (VAS) pain scores. Data on adverse events, postoperative ambulation (>6 hours/day), time of flatus and defecation, and hospitalization duration were recorded. RESULTS Pain scores of the study group were significantly lower compared with the control group on the first three postoperative days. No significant differences were found between the two groups in terms of adverse events. In the study group, the number of cases of postoperative ambulation was significantly more than the control group. The onset of flatus and defecation and duration of hospital stay in the study group were significantly shorter in the study group compared with the control group. CONCLUSIONS Parecoxib sodium combined with TAP block effectively reduced postoperative pain, improved ambulation, improved gastrointestinal function, and shortened hospitalization time following hepatectomy in patients with HCC without adverse effects.
