Effect of Ketalar to Prevent Postoperative Chronic Pain After Mastectomy

The recruitment status of this study is unknown. The completion date has passed and the status has not been verified in more than two years.

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.

Condition Intervention Phase
Pain Breast Cancer Drug: ketalar Phase 4
