Tegileridine provides superior analgesic efficacy over placebo for postoperative acute pain with a favorable safety profileTegileridine shows promise for managing pain after surgery

Key Takeaway
Consider tegileridine as a potential alternative for postoperative pain due to its favorable safety profile over morphine.

This meta-analysis evaluates the efficacy and safety of tegileridine at various doses for the management of postoperative acute pain in 1,011 patients. The study compares tegileridine against both placebo and morphine to determine its clinical utility.

The analysis indicates that tegileridine significantly reduced rSPID24 and rSPID12 compared to placebo, demonstrating superior analgesic efficacy. However, when compared directly to morphine, tegileridine showed no significant difference in rSPID12 but exhibited significantly weaker efficacy for rSPID24.

Regarding safety, total adverse events with tegileridine were higher than placebo but comparable to morphine. Notably, tegileridine demonstrated a more favorable safety profile than morphine regarding nausea and vomiting, which were similar to placebo levels in the tegileridine group. No significant difference was found between tegileridine and morphine regarding respiratory depression. These findings suggest tegileridine may be a viable alternative for postoperative acute pain management, though specific limitations were not reported.

How this fits prior evidence

This meta-analysis addresses a gap in pharmacological options for managing postoperative acute pain. While prior evidence highlights regional techniques like PECS II, TAP blocks, and S-PIP blocks to reduce morphine use or provide analgesia, this study evaluates tegileridine as a systemic alternative. It confirms that while tegileridine is superior to placebo, it is less effective than morphine for rSPID24.

Managing sharp, intense pain immediately following surgery is a major challenge for both patients and doctors. While morphine is a common choice, it often comes with heavy side effects that can make recovery uncomfortable. Researchers looked at tegileridine as a possible alternative to see how it stacks up against placebo and morphine.

In a review of data from over 1,000 patients, tegileridine proved much more effective than a placebo at reducing pain scores. When compared directly to morphine, tegileridine performed similarly in some measures but was significantly weaker than morphine in others. This suggests it works well for pain relief, even if it is not as potent as morphine.

One of the biggest wins for tegileridine is its safety profile. While it had more side effects than a placebo, those issues were similar to morphine's levels. However, patients taking tegileridine experienced much less nausea and vomiting than those taking morphine. These findings suggest tegileridine could be a useful option for managing post-surgery pain while keeping patients more comfortable.

What this means for you:
Tegileridine effectively reduces post-surgical pain with fewer instances of nausea and vomiting than morphine.

Common questions

How does tegileridine compare to morphine for surgical pain?

Tegileridine is effective at reducing pain scores compared to a placebo. When compared directly to morphine, tegileridine showed no significant difference in some measurements but was significantly weaker than morphine in others. While it provides relief, it may not be as strong as morphine for certain types of pain.

Are there side effects when taking tegileridine?

Tegileridine had more total adverse events than a placebo, but these were comparable to the levels seen with morphine. However, patients taking tegileridine experienced significantly less nausea and vomiting than those who took morphine, making it potentially easier to tolerate.

Is tegileridine safe for use after surgery?

The study found no significant difference in respiratory depression between tegileridine and morphine. While it has more side effects than a placebo, its profile regarding nausea and vomiting is much better than morphine's. Talk to your doctor about whether this medication is right for your specific recovery.

ObjectiveThis study aims to comprehensively evaluate the efficacy and safety of tegileridine at different doses in patients with postoperative acute pain through a meta-analysis.MethodsA systematic literature search was conducted across six databases from their inception to 24 March 2026 to identify all randomized controlled trials (RCTs) involving tegileridine for the treatment of postoperative acute pain. Meta-analyses were performed using RevMan 5.4 software.ResultsA total of four cohorts from three RCTs involving 1,011 patients were included. Compared with placebo, tegileridine significantly reduced rSPID24 and rSPID12, demonstrating superior analgesic efficacy. Compared with morphine, there was no significant difference at rSPID12; however, tegileridine exhibited significantly weaker efficacy than morphine at rSPID24. Safety analyses revealed that although the total adverse events with tegileridine were higher than with placebo, it remained comparable to that of morphine. The incidence of nausea and vomiting with tegileridine was similar to that with placebo and significantly lower than that with morphine. No significant difference was observed in the incidence of respiratory depression between tegileridine and morphine.ConclusionThis meta-analysis demonstrates that the efficacy of tegileridine was significantly superior to that of placebo, and it had a more favorable safety profile than morphine regarding nausea and vomiting, suggesting its potential as a viable alternative for postoperative acute pain.Systematic Review Registration[https://www.crd.york.ac.uk/prospero/view/CRD420261364062/1/0], PROSPERO CRD420261364062.
