opioid free anesthesia

Peking University People's Hospital · Phase 3 active Small molecule ✓ Verified May 2026

opioid free anesthesia is a local anesthetic Small molecule drug developed by Peking University People's Hospital. It is currently in Phase 3 development for General anesthesia for surgical procedures. Also known as: opioid free, OFA.

opioid-free anesthesia works by using a combination of local anesthetics and adjuvants to provide pain relief without the use of opioids.

Opioid-free anesthesia (OFA) is a type of anesthesia that does not involve opioids, and it has been studied in various conditions, including postoperative nausea and vomiting, opioid use, and implicit memorization. The exact mechanism of OFA is currently unknown, but it has been investigated as an alternative to traditional opioid-based anesthesia in clinical trials, such as the "Dreams or Implicite Memorization Under OFA" study.

Mechanism of action

opioid-free anesthesia typically involves the use of local anesthetics such as lidocaine or ropivacaine, combined with adjuvants like clonidine or ketamine to enhance analgesia and reduce the need for opioids. This approach can help reduce the risk of opioid-related side effects and promote a faster recovery.
