What's Happening?
A Cochrane review has found no solid evidence supporting the off-label use of ketamine for chronic pain relief. The review analyzed 67 trials involving over 2,300 participants and assessed five NMDA receptor antagonists, including ketamine. Results showed no clear benefit for ketamine in chronic pain management and highlighted an increased risk of adverse effects such as delusions, paranoia, and nausea. The evidence was rated low to very low certainty due to small study sizes and poor methodological quality.

Why It's Important?
The findings raise concerns about the widespread off-label use of ketamine for chronic pain, emphasizing the need for stronger evidence and high-quality trials. The review suggests caution in clinical settings, as ketamine's side effects can be distressing for patients. This could impact prescribing practices and encourage healthcare providers to seek alternative treatments with more robust evidence. The review also highlights the importance of conducting rigorous trials to ensure patient safety and efficacy in pain management.
What's Next?
The review may prompt further research into ketamine and other NMDA receptor antagonists, potentially leading to new trials that address the gaps identified. Healthcare providers might reconsider ketamine prescriptions for chronic pain, opting for treatments with proven efficacy. Regulatory bodies could use the findings to guide policy decisions on the use of ketamine, ensuring patient safety and promoting evidence-based practices.
