Effect of Ketalar to Prevent Postoperative Chronic Pain After Mastectomy
A Phase 4 study testing ketalar in people with Pain and Breast Cancer, run by Hospices Civils de Lyon at 1 site in France.
Trial summary
Prevalence of chronic pain after mastectomy is beyond 50% 3 months after surgery. This pain is related to a sensitization of the central nervous system through N-methyl-D-asparate (NMDA) receptors. Ketalar might prevent the occurrence of chronic pain by anti-NMDA properties after mastectomy. Read more about this study
