简要总结
The purpose of this study is to assess the effectiveness, safety and pharmacokinetics of Oral Nalbuphine in the treatment of postoperative pain following hemorrhoidectomy.
详细描述
• Primary Efficacy Endpoint: Pain assessment calculated as the area under the curve of VAS pain intensity scores through 48 hours.
• Secondary Efficacy Endpoints:
- Consumption of diclofenac (Day 1-2) via Intramuscular Injection (IM injection).
- Time from the end of operation to the first IM injection diclofenac dose
- Brief Pain Inventory (BPI).
- Patient satisfaction.
