Persistent pain affects nearly half of all people seeking medical care in the US alone, and accounts for at least $80 billion worth of lost productivity each year. Among all types of chronic pain, neuropathic pain stands out: this is pain resulting from damage or disease of the somatosensory nervous system, and remains largely untreatable. With few available treatment options, neuropathic pain represents an area of significant and growing unmet medical need. Current treatment of peripheral neuropathic pain involves several drug classes, including opioids, gabapentinoids, antidepressants, antiepileptic drugs, local anesthetics and capsaicin. Even so, less than half of patients achieve partial relief. This review discusses a novel approach to neuropathic pain management, based on knowledge of: the role of glia and mast cells in pain and neuroinflammation; the body’s innate mechanisms to maintain cellular homeostasis when faced with external stressors provoking, for example, inflammation. The discovery that palmitoylethanolamide, a member of the Nacylethanolamine family which is produced from the lipid bilayer on-demand, is capable of exerting anti-allodynic and anti-hyperalgesic effects by down-modulating both microglial and mast cell activity has led to the application of this fatty acid amide in several clinical studies of neuropathic pain, with beneficial outcome and no indication of adverse effects at pharmacological doses. Collectively, the findings presented here propose that palmitoylethanolamide merits further consideration as a disease-modifying agent for controlling inflammatory responses and related chronic and neuropathic pain.

Italian and Dutch PEA

Palmitoylethanolamide is especially in Italy and the USA at the moment hot for the treatment of glaucoma. We prefer treatment either with the Italian PEA tablets, based on PEA-um or PEA-m, or by administrating the Dutch PEA capsules containing PEA-opt. Dutch capsules do not contain any chemical excipients and are 100% pure in vegetarian capsules.

Only for these the Dutch and the Italian formulations long term safety and efficacy data gathered under the supervision of MDs are available. And only for these formulations (PEA-um, PEA-m and PEA-opt) there are currently data available proving that after intake PEA levels in the body significantly rise. Such data do not exist for me-too PEA formulations.
