Exclusion criteria

* Single-column hemorrhoidectomy or hemorrhoidectomy without an internal component * Body weight less than 50 kilograms (110 pounds) * History of hypersensitivity or idiosyncratic reactions or amide-type local anesthetics, opioids, or propofol * Current painful physical condition or concurrent surgery other than hemorrhoids that may require analgesic treatment (such as non-steroidal anti-inflammatory drug \[NSAID\], opioid, selective serotonin reuptake inhibitor \[SSRI\], tricyclic antidepressant, gabapentin, pregabalin) in the postoperative period for pain that is not strictly related to the hemorrhoidectomy procedure and may confound the postoperative assessments * Concurrent fissurectomy * Use of any NSAID including selective COX-2 inhibitor, opioid, SSRI, tricyclic antidepressant, gabapentin, or pregabalin within three days of surgery * Use of acetaminophen within 24 hours of surgery * Chronic users of analgesic medications, including taking opioid medications for more than 14 days in the last 3 months, or non-opioid pain medications more than 5 times per week * History of, suspected, or known addiction to or abuse of drugs or alcohol within the past two years * Current use of glucocorticosteroids or use of glucocorticoids within one month of enrollment into this study * HIV infection or hepatitis * Currently pregnant, nursing, or planning to become pregnant during the course of the study or within one month of study drug administration * Any psychiatric, psychological, medical, or laboratory condition that the investigator feels makes the subject an inappropriate candidate for this clinical trial * Subjects who have received another investigational drug within the longer of the last 30 days or 10 elimination half-lives * Previous participation in a SKY0402 study * Failure to pass drug and alcohol screen
