Oliceridine hydrochloride is primarily used in the management of moderate to severe acute pain in adults, particularly in clinical settings where rapid pain relief is essential. It is administered intravenously, making it suitable for use in hospitals or during post-surgical recovery. The drug acts as a mu-opioid receptor agonist but is designed to provide effective analgesia with a potentially improved side effect profile compared to traditional opioids, such as reduced respiratory depression and gastrointestinal effects. Its targeted mechanism allows for quicker onset of pain relief and better tolerability, making it a valuable option for patients requiring immediate and controlled pain management.
