Sameridine was developed as a compound with both local anesthetic and opioid properties (partial micro-opioid receptor agonist). This drug participated in clinical trials when administered intrathecally to provide anesthesia for surgery and extended postoperative analgesia. However, further development of this drug was discontinued.
