Does Oliceridine cause less nausea and vomiting compared to sufentanil?
Oliceridine is a newer pain medicine designed to reduce common side effects like nausea and vomiting. When compared to sufentanil, a standard opioid used for pain, studies indicate that Oliceridine lowers the risk of these specific side effects. This difference is important for patients recovering from surgery who want to avoid feeling sick.
What the research says
A study involving 138 elderly patients undergoing knee arthroplasty found that Oliceridine provided pain relief comparable to sufentanil. Over 48 hours, the data showed a lower rate of postoperative nausea and vomiting in the Oliceridine group compared to the sufentanil group 24. The researchers confirmed that Oliceridine met the criteria for non-inferiority regarding pain control while demonstrating a clear advantage in reducing these adverse reactions 24.
The mechanism behind this benefit involves how the drug interacts with the body's receptors. Oliceridine acts as a biased agonist, meaning it activates specific pathways that provide pain relief while avoiding the pathways that trigger nausea and vomiting. In a separate study comparing a similar biased opioid to morphine, the biased drug caused less nausea and less reduction in breathing compared to standard opioids 5.
