- Opioids target kappa and NMDA receptors that can lead to central nervous system sensitization and therefore increased pain
- For patients with opioid-induced hyperalgesia (OIH), oral ketamine (25-50 mg) can be used to treat their pain as it targets the NMDA receptor
- Other treatments are IV magnesium, NSAIDs, Tylenol, and clonidine
- Buprenorphine and methadone are options for chronic pain management in the setting of OIH
