Nalbuphine is a synthetic opioid analgesic used to treat moderate to severe pain. It acts as a mixed agonist-antagonist at opioid receptors—agonist at kappa-opioid receptors and antagonist at mu-opioid receptors. It is primarily approved for use in the management and relief of pain, pre- and postoperative analgesia, and as a supplement to balanced anesthesia. It is currently approved for medical use in several countries.
