Able to communicate well with the investigator and comply with the requirements of the study. Exclusion Criteria: Use of any alcohol-containing products, prescription medications or over-the-counter, non-prescription preparations (including herbal preparations) within 2 weeks prior to study entry unless deemed acceptable by the Investigator (except up to 5 doses of ≤ 1000 mg of acetaminophen or ≤ 400 mg ibuprofen within this 2 week period). Alcohol or caffeine ingested within 48 hours prior to dosing. Significant illness within 2 weeks prior to dosing. Participation in any clinical investigation within 2 months prior to dosing or longer as required by local regulation. Donation or loss of more than 500 mL of blood within 3 months prior to dosing. Donation or loss of more than 250 mL of blood within 2 months prior to dosing. Presence of cardiovascular disease. Presence of gastrointestinal disease. Presence of asthma or lung disease. Presence of liver disease or liver injury as indicated by an abnormal liver function profile such as AST, ALT, gamma-GT, Alkaline Phosphatase, or Total Bilirubin. (value of AST or ALT above 3 times of the upper limit of the normal range; other items clinically significant abnormality judged by investigator). Presence of impaired renal function as indicated by abnormal creatinine or BUN values or abnormal urinary constituents. (value of creatinine or BUN beyond the range from -20% of the lower limit of the normal range to +20% of the upper limit of the normal range; other items clinically significant abnormality judged by investigator) Presence of neurological disease. Presence of psychiatric disease. Subject is positive for HIV immunology test. A known hypersensitivity to nalbuphine or its analogs. History of drug or alcohol abuse within 12 months prior to dosing.

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Blood concentration of Nalbuphine HCl | Protocol-specified pharmacokinetic parameters will be determined from blood samples collected after each administration of study drug to assess the relative bioavailability of SDE. | Period I: pre-dose (0 h) and 0.083, 0.25, 0.5, 1, 1.5, 2, 3, 4, 6, 8, 12, and 24 hours post dose for Bain®, Nalbuphine HCl IM injection ; Period II: pre-dose (0 h) and 6, 12, 24, 48, 72, 96, 120, 168, 216, 264 and 336 hours post dose for SDE IM injection |
