In his multicenter, double-blinded, randomized, placebo, controlled study we evaluated the analgesic and opioid-sparing efficacy of a preoperative dose of IV parecoxib followed by oral valdecoxib in treating pain associated with elective laparoscopic cholecystectomy. Patients were randomized to receive a single IV dose of parecoxib 40 mg (n = 134) or placebo (n = 129) 30-45 min before induction of anesthesia. Six to 12 h after the IV dose, the parecoxib group received a single oral dose of valdecoxib 40 mg, followed by valdecoxib 40 mg qd on postoperative days 1-4, then 40 mg qd prn days 5-7. The placebo IV group received oral placebo on an identical schedule. All patients were allowed supplemental IV fentanyl as needed during the first 4 h postoperatively (T0-240 min) followed by hydrocodone 5 mg/acetaminophen 500 mg (Vicodin®; 1-2 tablets orally every 4-6 h as needed). Patients taking parecoxib used 21% less fentanyl than those receiving placebo (P = 0.011). The mean area under the curve of pain intensity (PI) scores over time from T0-240 min was 55.2 for parecoxib and 61.2 for placebo (P = 0.083). At T180 and T240 min, mean PI score was 7.0 and 7.6 points lower in the parecoxib group, respectively (P < 0.02). Fewer patients on valdecoxib required supplemental analgesics (P < 0.05) after discharge. At T240 min and at day 7, Patient's and Physician's/Nurse's Global Evaluations were significantly better in the parecoxib/valdecoxib group (P < 0.05). Incidences of adverse events, adverse events causing withdrawal, and serious adverse events were less for parecoxib/valdecoxib than for placebo. The authors conclude that preoperative parecoxib is a valuable opioid-sparing adjunct to the standard of care for treating pain after laparoscopic cholecystectomy, and subsequent treatment with oral valdecoxib extends this clinical benefit.
