Chemotherapy-induced neuropathic pain continues to pose significant challenges to therapeutic attempts. Memantine, a N-methyl D-aspartate (NMDA) receptor blocker, is currently used in the treatment of patients with moderate to severe Alzheimer’s disease. NMDA receptors are suspected to be involved in chronic pain pathogenesis by lowering sensitivity thresholds to mechanical and thermal stimuli. The aim of this study was to evaluate the analgesic effect of memantine in a paclitaxel-induced neuropathic pain model in rats. Sensitivity thresholds decreased for the paclitaxel treated group, and returned to normal values for the memantine treated ones. Results indicate antiallodynic and antihyperalgic properties for paclitaxel induced neuropathic pain.
