Design
Laboratory study
Subjects
Mice with paclitaxel-induced chemotherapy peripheral neuropathy
Dose used in the study
Ultramicronised palmitoylethanolamide 30 mg/kg orally, one hour after the last paclitaxel injection, for 7 days; paclitaxel 8 mg/kg intraperitoneally every other day for a week; the antagonists AM281 (1 mg/kg) and GW6471 (2 mg/kg) given 30 minutes before palmitoylethanolamide in separate experiments
Duration
7 days of palmitoylethanolamide treatment
What was measured
Pain hypersensitivity, spinal and hippocampal pro-inflammatory cytokines, and depressive- and anxiety-like behaviours; the role of PPAR-alpha and CB1 receptors using antagonists

What the authors reported

Ultramicronised palmitoylethanolamide reduced the development of hypersensitivity, which went with reduced spinal and hippocampal pro-inflammatory cytokines and reduced depressive- and anxiety-like behaviours. The PPAR-alpha antagonist GW6471 and the CB1 antagonist AM281 blocked these behavioural and antinociceptive effects.

Limits of this study

A mouse model of chemotherapy-induced neuropathy; it cannot show effect in people undergoing chemotherapy. The authors declare no conflict of interest.
