Pain, Postoperative
Conditions
Brief summary
The primary objective of this study is to demonstrate the opioid-sparing efficacy of parecoxib 40 mg intravenously given as a loading dose followed by 20 mg intravenously in the 24 hours after the end of surgery.
Detailed description
The study was terminated due to lack of recruitment due to competing alternative operation methods on 13September 2010. The decision to terminate the trial was not based on any safety concerns.
Interventions
Parecoxib 40 milligrams (mg) administered intravenously immediately post surgery, followed 20 mg every 12 hours until 48 hours post surgery, total 5 doses. Participants also received Patient-Controlled Analgesia (PCA) 1 mg per dose, maximum 40 mg/4 hours, and if necessary, bolus (2 to 5 mg) before or after enabled PCA.
Matching placebo administered intravenously immediately post surgery and every 12 hours until 48 hours post surgery, total 5 doses. Participants also received PCA (1 mg per dose, maximum 40 mg/4 hours, and if necessary, bolus (2 to 5 mg) before or after enabled PCA

Eligibility
Inclusion criteria
* The patient's ASA physical status is 1 or 2 and he has a low risk (i.e.,\<10%) of developing an acute coronary event within the next 10 years according to the PROCAM risk assessment calculator. * The patient is scheduled to undergo routine radical prostatectomy performed under a standardized regimen of general anesthesia, and is expected to experience moderate to severe postsurgical pain in the absence of postoperative analgesia.
Exclusion criteria
* The patient has a history of uncontrolled chronic disease or a concurrent clinically significant illness or medical condition such as a diagnosed chronic pain condition, which, in the Investigator's opinion, would contraindicate study participation or confound interpretation of the results * The patient has a history or current presence of congestive heart failure (NYHA II-IV), established ischaemic heart disease, peripheral arterial disease and / or cerebrovascular disease.
