Primary Outcome Measures:
  • Combined incidence of the number of patients with at least 1 confirmed clinically relevant adverse event (CRAE) [ Time Frame: Day 30 ]

Secondary Outcome Measures:
  • Combined incidence of the number of patients with at least 1 reported CRAE and the combined incidence of the number of patients with specific reported CRAEs summarized according to the categories listed above [ Time Frame: Day 30 ]
  • Rate of supplemental analgesia consumed [ Time Frame: Days 1-10 ]
  • Vital signs [ Time Frame: Day 30 ]
  • Summed Pain Intensity (SPI) of sternotomy alone and overall body pain over 8 hours (SPI 8) [ Time Frame: Day 1 ]
  • Opioid-related Symptoms Distress Scale (OR-SDS) [ Time Frame: Days 1-10 ]
  • Time to last Patient Controlled Analgesia (PCA) dose
  • Recovery measures (length of stay, intensive care unit/hospital recovery and eligibility for discharge)
  • Combined incidence of the number of patients with specific confirmed CRAEs in categories of cardiovascular thromboembolic CRAEs, renal CRAEs, upper gastrointestinal ulcer CRAEs, and wound healing complication CRAEs [ Time Frame: Day 30 ]
  • Adverse events [ Time Frame: Day 30 ]
  • Serious adverse events [ Time Frame: Day 30 ]
  • Clinical laboratory assessments [ Time Frame: Day 30 ]
  • Peak Pain Intensity (PPI) of sternotomy alone and overall body pain [ Time Frame: Days 1-10 ]
  • Patient's and Physician's Global Evaluation of Study Medication [ Time Frame: At time of transition from intravenous to oral medication and final visit/early termination ]
  • Modified Brief Pain Inventory-short form (mBPI-sf) [ Time Frame: Days 1-10 ]
  • SPI of sternotomy alone and overall body pain over 12 hours (SPI 12) and 24 hours (SPI 24) [ Time Frame: Days 1-10 ]

Study Start Date: January 2003
Study Completion Date: January 2004
Arms Assigned Interventions
Placebo Comparator: A Drug: Parecoxib Sodium/Valdecoxib
Parecoxib sodium 40 mg intravenous (IV) on the day after surgery (Day 1) following recovery from anesthesia, contingent on an acceptable postoperative status, verification of baseline eligibility, and lack of perioperative complications. A second dose of parecoxib sodium 20 mg IV was administered on Day 1. On the day following surgery, patients received parecoxib 20 mg IV at 8 am and each subsequent dose was administered at 12-hour intervals. After receiving at least 6 doses of IV parecoxib sodium, patients were transitioned to oral valdecoxib 20 mg taken at 12-hour intervals until the total treatment duration of 10 days had been completed.
Experimental: B Drug: Placebo/Valdecoxib
Patients received placebo matched to parecoxib sodium 40 mg IV on Day 1 following recovery from anesthesia, contingent on an acceptable postoperative status, verification of baseline eligibility, and lack of perioperative complications. A second dose of placebo matched to parecoxib sodium 20 mg IV was administered on Day 1. On the day following surgery, patients received placebo matched to parecoxib sodium 20 mg IV at 8 am and each subsequent dose was administered at 12-hour intervals. After receiving at least 6 doses of IV placebo, patients were transitioned to oral valdecoxib 20 mg taken at 12-hour intervals until the total treatment duration of 10 days had been completed.
Experimental: C Other: Placebo/Placebo
Patients received placebo matched to parecoxib sodium 40 mg IV on Day 1 following recovery from anesthesia, contingent on an acceptable postoperative status, verification of baseline eligibility, and lack of perioperative complications. A second dose of placebo matched to parecoxib sodium 20 mg IV was administered on Day 1. On the day following surgery, patients received placebo matched to parecoxib sodium 20 mg IV at 8 am and each subsequent dose was administered at 12-hour intervals. After receiving at least 6 doses of IV placebo, patients were transitioned to oral placebo matched to valdecoxib 20 mg taken at 12-hour intervals until the total treatment duration of 10 days had been completed.
