Efficacy and safety of oliceridine treatment in patients with postoperative pain: a systematic review and meta-analysis of randomized controlled trials

Our aim was to conduct a systematic review and meta-analysis to examine the efficacy and safety of oliceridine in patients with postoperative pain.Four databases were searched from the beginning of the database to the present. We included all randomized controlled trials (RCT) that evaluated the efficacy and safety of oliceridine in patients with postoperative pain. Our endpoints were the proportion of treatment responders to the oliceridine regimen and the incidence of adverse effects such as nausea and vomiting.The analysis showed that more patients responded significantly with oliceridine compared to placebo. The proportion of treatment responders to oliceridine was comparable to that of morphine. Oliceridine had analgesia effects similar to morphine compared to placebo. The incidence of respiratory safety events was significantly lower with oliceridine compared to morphine. Oliceridine was significantly associated with more adverse events such as nausea and vomiting compared to placebo. The safety profile of oliceridine was superior to morphine compared to morphine.Our systematic review and meta-analysis showed that oliceridine is an effective and safe intravenous analgesic in patients with postoperative pain, producing rapid postoperative analgesic and usually well tolerated, and reducing incidence of adverse events compared to morphine.CRD42023391581.
