ClinConnect Summary

This clinical trial is studying a new medication called YZJ-4729 Tartrate Injection to help relieve pain after orthopedic surgery, which is surgery on bones and joints. The main goal is to see how well this injection works to reduce pain and to make sure it is safe for patients. The trial is not yet recruiting participants, but when it begins, it will welcome adults aged 18 to 75 who have moderate to severe pain after their surgery.

To be eligible for the study, participants will need to understand the purpose of the trial and agree to take part by signing a consent form. They should also have a body mass index (BMI) between 18 and 28, and their pain level must be at least a 4 on a scale of 0 to 10 within four hours after surgery. However, people with certain health conditions, such as allergies to opioids, serious nervous system issues, or high blood pressure, may not be able to participate.
