Safety and Analgesic Efficacy of the Biased μ-Opioid Receptor Agonist Tegileridine for Post-Operative Analgesia in Patients Undergoing Bariatric Surgery
A Phase 3 study testing Tegileridine (tegileridine fumarate injection, IV) and Sufentanil in people with Pain Management and Overweight , Obesity, run by The First Hospital of Jilin University at 1 site in China.
Trial summary
This single-center, stratified randomized double-blind trial tests tegileridine, a new pain drug, for pain relief after weight-loss surgery. Researchers will compare tegileridine with standard opioid pain medicine. Eligible patients having bariatric surgery will be randomly assigned to one of the two treatment groups.

About this study
Official title: Safety and Analgesic Efficacy of the Biased μ-Opioid Receptor Agonist Tapentadol in Patients Undergoing Bariatric Surgery
This single-center, stratified randomized double-blind trial tests tegileridine, a new pain drug, for pain relief after weight-loss surgery. Researchers will compare tegileridine with standard opioid pain medicine.
Eligible patients having bariatric surgery will be randomly assigned to one of the two treatment groups. Patients and study teams will not know which treatment each participant receives. Participants will be grouped based on whether they have obstructive sleep apnea (OSA).

The primary measurement is postoperative recovery quality in the first 24 hours after surgery using the QoR-15 survey. The study will also track pain scores, rescue pain medication use, and drug side effects for 7 days after surgery.
There is no guaranteed benefit for participants. Study pain medicines may cause side effects. Doctors will provide rescue treatment for uncontrolled pain.
- Being tested
- Tegileridine (tegileridine fumarate injection, IV), Sufentanil
- Medical subject headings
- Agnosia, Overweight, Obesity, Respiratory Aspiration, Sleep Wake Disorders
What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Tegileridine (tegileridine fumarate injection, IV)Drug
Tegileridine will be given to participants for postoperative pain relief after bariatric surgery.
SufentanilDrug
Sufentanil, a standard opioid analgesic, will be given to participants to manage postoperative pain following bariatric surgery.
| Study group | Role | What they receive |
|---|---|---|
| Tegileridine Group | Experimental | Not described Receives: Drug: Tegileridine (tegileridine fumarate injection, IV) |
| Standard Opioid Group | Active comparator | Not described Receives: Drug: Sufentanil |
What is being measured
The primary outcome is the main question the study is designed to answer.
Quality of Recovery-15 (QoR-15) Score at 24 Hours After Surgery
The Quality of Recovery-15 (QoR-15) is a validated questionnaire used to assess the quality of postoperative recovery. The total score ranges from a minimum of 0 to a maximum of 150. A higher score indicates a better quality of recovery.
Measured: 24 hours after bariatric surgery
