• Female subjects are eligible only if all of the following apply:
• Not pregnant (subjects of child-bearing potential must have a negative serum beta-human chorionic gonadotropin (B-hCG) pregnancy test at screening and a negative urine pregnancy test before surgery);

• Be willing to complete the pain assessments and return to clinic as scheduled.
• Subjects must experience postoperative pain (Day 1) that is at least moderate as measured by a NRS score ≥ 4 on a 0-10 NRS, less than 9 hours after discontinuing the nerve block.

You may not qualify if…

• Have an uncontrolled medical condition, serious intercurrent illness, clinically significant general health condition, or extenuating circumstance that may significantly decrease study compliance or otherwise preclude their participation in the study.

• Have glycosylated hemoglobin (2c) > 7%.
• Have Addison's disease, benign prostatic hyperplasia, or kidney disease or other conditions as outlined in the Investigator's Brochure or the Percocet and Oxycontin Package Inserts that are contraindicated for use.

• Have made a plasma donation within 7 days prior to Day -1.
• Have a known allergy or hypersensitivity to any opioid analgesics, naltrexone, anesthetics (eg, propofol), acetaminophen, NSAIDs (eg, ibuprofen or naproxen, ketorolac) or any of the excipients

• Have a history of seizures or history of serious head injury.
• Must not be a member of a vulnerable population as defined by the Code of Federal Regulations Title 45, Part 46, Section 46.111(b), including but not limited to employees (temporary, part-time, full-time, etc.) or a family member of the research staff conducting the study, or of the Sponsor, or of the Clinical Research Organization.
