Polyamine-free Diet to Prevent Post Surgery Hyperalgesia

Abstract

After surgery, sensitization and hyperexcitability of central nervous system result in acute and long lasting postoperative pain. It has been shown that N-methyl-D-aspartate (NMDA) receptors antagonist (such as ketamine) prevent this adverse neuroplasticity and potentiate analgesic drugs efficacy. Polyamines (putrescine, spermidine, spermine) are essential components of cells functioning and are also known as allosteric modulators of NMDA receptors. In animal studies, polyamine-free diet has confirmed these antinociceptive properties. This research aims at evaluating anti hyperalgesic properties of polyamine-free diet in women operated on breast cancer versus kétamine
