Several treatment modalities are available within the field of neuropathic pain and neuropathy.

een PEA-houdend product and PeaPure: questions and answers

What exactly is een PEA-houdend product  and PeaPure?

In this page many clinical and patient driven questions will be discussed. This page is under construction. A website has been created for palmitoylethanolamide related science only.

een PEA-houdend product and PeaPure are brandnames for supplements containing a body own molecule, palmitoylethanolamide, against pain and inflammation.  

een PEA-houdend product however contains magnesium stearate, a alien fat for our body, undigestable and an excipient doctors recommend to avoid.

All scientific information is discussed in this review.

Multimodal therapy in neuropathic pain: 2 is more than 1!

The famous Dutch surgeon Noordenbos wrote in 1959: "One-one synaptic transmission must be the exception rather than the rule in the nervous system. Any nerve cell located in the anterior horn. . . could hardly be expected to synapse at higher level with one such similar cell only. It will probably send ramifications to many other locations, and in turn be acted upon by the ramifications of many other cells. . . Far from being a continuous chain of short neurons, these fibres must constitute links in an extremely complicated nerve net in which, within limits, everything synapses more or less with everything else." It is clear that half a century later our therapy of pain is based on these deep insights of Noordenbos, and multimodal therapy is now the hallmark of how to treat neuropathic pain. This is because it is difficult to treat neuropathic pain with one drug only. In our centre we nearly always prescribe two or more oral drugs and mostly also topical creams and supplements together to get the patients out of the red zone of discomfort.

Neuropathic low blood pressure: Droxidopa

Patients suffering from small fibre neuropathy sometimes also suffer from difficult to treat low bloodpressure. In the Orient there is a registered drug for this dindication: L-DOPS (L-threo-dihydroxyphenylserine; Droxidopa; SM-5688). Droxidopa is a synthetic amino acid precursor which acts as a prodrug to the neurotransmitters norepinephrine (noradrenaline) and epinephrine (adrenaline). Unlike norepinephrine and epinephrine themselves, L-DOPS is capable of crossing the protective blood-brain barrier (BBB).

Palmitoylethanolamide protects against side-effects anticancer drugs

Kahler’s disease is cancer of certain white blood cells, the plasma cells, and leads to death, mostly within 3-4 years. It is the second most frequent occuring forms of blood cancer, after non-Hodgkin’s disease. Initially patients can respond to chemotherapy, but treatment resistance often occurs. Furthermore, side effects such as nerve pain and nerve disfunctions (painful neuropathy) are dose limiting and thus optimal treatment of patients is not possible, as the chemotherapy needs to be stopped or reduced. Therfore patients cannot finish the course of chemotherapy and run a higher risk of relapse or recurrence of their cancer. Since years science searches for compounds to protect the nerve function, in order to enable patients suffering from MM to proceed being treated with chemotherapy.

Therefore it is highly important to point out that recently a natural occuring compound palmitoylethanolamide (PEA) has been identified in a clinical trial in MM patients, which indeed counteracts the side-effects of chemotherapy in blood cancer and restores nerve functions.

Italian neurologists from the neurological department of professor Cruccu, of the university of Rome, assessed the effect of PEA on pain and nerve function in patients with chemotherapy-induced painful neuropathy.

Evidence based medicine, patient centered medicine and the place of PEA

ebm.jpg Why the supplement PEA ( PeaPure) in chronic painstates? Is Evidence-Based Medicine Patient-Centered and Is Patient-Centered Care Evidence-Based? The patient should be the ultimate judge. Therfore Dr Painless points out that treating patients suffering chronic pain with the non-prescription drug een PEA-houdend product makes sense. Evidence-based medicine is a rather young concept that entered the scientific literature in the early 1990s.

It has basically a positivistic, biomedical perspective. Its focus is on offering clinicians the best available evidence about the most adequate treatment for their patients, considering medicine merely as a cognitive-rational enterprise. In this approach the uniqueness of patients, their individual needs and preferences, and their emotional status are easily neglected as relevant factors in decision-making.

Anodyne Therapy System® for neuropathy: not proven!

Surfing the net you may encounter many different treatments for neuropathy, and the anodyne therapy is one of those. In the internet you may find advertorials like the following: f you suffer from diabetic neuropathy, you may benefit from Anodyne Therapy–a non-invasive treatment that increases circulation and reduces the pain associated with peripheral neuropathy. The Anodyne Therapy System® helps to release nitric oxide from the red blood cells of patients suffering from diabetes. It does this with monochromatic infrared energy (MIRE) administered through flexible pads containing infrared diodes.

Thalamus pain, mast cells and PEA: a new treatment hypothesis

Thalamic pain after stroke is one of the most difficult to treat central painsyndromes. New therapeutic inroads are clearly needed, as the classical anti-neuropathic analgesics are not effective. In the future times we will need anti-gliopathic analgesics, as we pointed out elswere in our website.

The thalamus is a part of the brain were many mast cells reside. Mast cells play an important role in neuropathic pain. Palmitoylethanolamide (PEA) is a body-own fatty acid, synthetized in all our membranes, with mast cell stabilizing properties. PEA is registered in the catagory of medical food in Europe, and especially due to absence of side effects might be a promising new therapy for central thalamic pain.

Treatment of CRPS pain acc to protocol including ketamine (&DMSO) creams

In our clinic we developed a new treatment protocol for pains in CRPS, Sudeck’s dystrophic pains. We combine various treatments, all with a low propensity for side-effects. Basically our treatment protocol consists of:

1. Topical analgesic creams:

a. start with ketamine 10% racemic cream and on top of it (if necessary) DMSO 50% cream. 

b. or switch to amitriptyline 10% cream ( with/without DMSP 50%)

c. switch to een PEA-houdend product cream on top of either one of the creams before (consisting of the immune-modulator adelmidrol and capsaicine low concentration)

Creams in addition to:

2. een PEA-houdend product (palmitoylethanolamide) 600 mg twice daily.

Start with 20-30 days on een PEA-houdend product powder sublingually (melt in saliva under tongue, not to swallow, but to resorp in the mounth, and after treat with een PEA-houdend product 600 mg tablets twice daily. (order by www.ergomax.nl)

Topical creams in CRPS: background 

Chronic severe pain in Sudeck or CRPS we treat with a combination of various topical creams, especially a 10% ketamine cream, in severe cases together with DMSO 50% cream. Topical analgesics have clearly advantages over systemically administered medications. This is especially true for racemic ketamine. The reduction or elimination of side-effects is one of the major advantages.

Many patients are totally unable to ingest ketamine, but as a cream the application of ketamine is no problem. We treated already 40 patients without any problems, and a Canadian academic group decribed another group of 60 patients. Topical analgesics differ from transdermal delivery methods in that prescribers use topical applications to deliver local, rather than systemic effects.

In our institute we have developed a variety of special-compounded creams to improve our patients’ experience with intractable pain due to Sudeck / CRPS. Ketamine 10% is one example.We also developed amitriptyline cream, baclofen cream and gabapentine creams. 

Our compounded ketamine 10% cream can be used for specific patients in e.g. the Netherlands, Germany and the UK if the physicians order a prescription document at infoneuropathie.nu.gif

Low dose naltrexone for neuropathic pain

Low dose naltrexone is popular in the alternative treatment world. It is a bit strange, as this molecule is quite non-alternative. But low dose naltrexone (LDN) is recommended on lay internetsites for a multitude of diseases, from MS to cancer. That always provokes anti-bodies by doctors, but naltrexone indeed has anti-inflammatory properties. It might be an interesting treatment option for  treatment refractory neuropathic pain patients.

Pain with hernia and treatment with palmitoylethalonamide ( PeaPure)

Heavy neuralgia radiating to the leg is also called sciatica or lumbosacral radiculopathy. Doctors have called this neuritis or neuritis of the sciatic nerve, the Nervus Ischiadicus, for a long time. This old concept has now been given a complete new turn.

Sciatica is caused by mechanic pressure by an intervertebral disc on the beginning of the sciatic nerve, the so-called nerve root within or just outside the vertebral column. Because of that pressure the nerve becomes inflamed and then the pain starts usually quite sudden. Then an inflammation that is maintained by the pressure on that nerve, the hernia, starts.

Palmitoylethanolamide (PEA): information for MD’s

pea.jpeg

Palmitoylethanolamide (‘PEA’) is a endogenous compound and is in Europe available for the treatment of chronic pain and chronic inflammation. Most clinical data have been gathered and published around its efficacy in various neuropathic painstates, such as in diabetes, carpal tunnel syndrome, sciatic pain, and we outline these indications and the clinical and preclinical data below. 

Under the follow link an extensive review for specialists can be downloaded. The article appeared in The Open Pain Journal (2012) 

Palmitoylethanolamide has be described as an endogenous fatty acid amide, belonging to the class of lipid signaling molecules (autocoids). Since 50 years of research around this molecule, the last decade the number of scientific papers on PEA’s biological and clinical activity has been expanded to nearly 400.

PEA has been demonstrated to bind to a receptor in the cell-nucleus (a nuclear receptor, PPAR), a number of other receptors, and therefore it exerts a great varity of biological functions related to chronic pain and inflammation. It is considered as a breakthourgh in the treament of chonic pain, and with PEA a new mechanism of action in the world of analgesics has been introduced and validated in a great number of studies.

PEA can be seen as a glia modulator and proof of principle (POP) as well as proof of concept (POC) has been generated via PEA studies of glia as an important factor in the genesis of neuropathic pain.

Brandnames of drugs containing PEA 

PEA is available under various brandnames: een PEA-houdend product and een PEA-houdend product in Italy and Spain, and as PeaPure (JP Russell Science Ltd) for the rest or the world. PeaPure is available in Europe as a food supplement. 

In een PEA-houdend product and the active ingredient is palmitoylethanolamide. In een PEA-houdend product and een PEA-houdend product excipients like magnesium stearate, povidone and polisorbate are added. In the een PEA-houdend product sachets a sweetener has been added, sorbitol.

In PeaPure the sole content is palmitoylethanolamide (no excipients).

Intractable neuropathic pain in Diabetes treated with palmitoylethanolamide and topical cream

Case description

A 53 year old famale patient suffered from diabetes type II since more than 10 years. She developed severe pains at the age of 48 and was totally refractory for many analgesics. Prescription of gabapentine, amitriptyline, pregabalin and carbamazepine remained unsuccesful in reducing her pains. On the numeric rating scale (NRS) for pain she scored 8 over 10.

She was a candidate for a spinal cord stimulator and wished first to follow our treatment protocol for treatment-resistant neuropathic pains, based on palmitoylethanolamide ( PeaPure).

Low dose Intravenous Ketamine in Refractory Neuropathic Pain

Treatment of refractory neuropathic pain is a clinical challenge. However, many new case reports and small clinical trials suggest that the N-methyl-D-aspartic acid (NMDA) receptor antagonists ketamine may be clinically useful in treating cases of neuropathic pain. Here a case report. This case report supports the idea that ketamine can be useful in the reduction of refractory chronic neuropathic pain and that the effect of ketamine can persist for many weeks after treatment.

PEA influences PPAR

One of the recent insights regarding the workingmechanism of PEA (palmitoylethanolamide) is that this molecule influences PPAR-alpha. PPAR-apha is a receptor located in the nucleus of the cel with a long name: peroxisome proliferator-activatedreceptor alpha. PEA is available in its purest form as PeaPure. PeaPure contains PEA only. een PEA-houdend product contains PEA too, but around 60%; Pevliven contains between 60-40% PEA.

Combination of analgesics in neuropathic pain

Treating neuropathic pain has to follow a multimodel painrelief approach. here we quote some lines from an FDA document concering pain treatment. An approach to improving pain control that addresses concerns with adverse events is to make use of a combination of different analgesics. By combining drugs lower doses can of each individual analgesics can be prescribed. In addition to the potential safety benefits of combination therapy, other potential advantages to use of a combination of analgesic drugs include the potential to overcome tolerance, improve efficacy, and decrease time- to-onset limitations of monotherapy.

Carpal tunnel syndrome treated with PEA

median_nerve_in_ct.gifCarpal Tunnel Syndrome (CTS) is the most common compression neuropathy. It is the reason for pain and functional impairment. On the picture we see in yellow the median nerve, being compressed under a ligament in the wrist. This gives rise to chronic pain. Pain normally can be reduced with oral neuropathic analgesics. However, the side effects of most of the NSAIDS limit its use.  

Palmitoylethanolamide (PEA), a fatty acid occuring naturally in our body, has also neuropathic pain reducing properties. Furthermore, it stabilizes mast cells, present in the carpal tunnel. Besides the pain reducing effect, PEA has also neuroprotective properties. To evaluate the clinical effects of PEA in CTS, Italian researchers randomised 28 diabetic patients with CTS, in two groups: one group received PEA twice daily 600mg and the other group received placebo.

Palmitoylethanolamide (PEA) for neuropathic pain

neupsig1.jpg

Palmitoylethanolamide: in 2012 more than 300 entries in pubmed for this interesting molecule!

The internationalizarion of PEA started at the Third International Congress on Neuropathic Pain, Athens, Greece, May 27 – 30, 2010.

A. Biasiotta, S. et al presented a poster which demonstrated a clinical relevant and electrophysiological measurable effect from this rather unknown compound classified as medical food, palmitoylethanolamide. The compound is available as dietfood for medical purposes (brandname een PEA-houdend product) in various European contries and under the brandname PeaPure (a supplement) via the internet.

This is very interesting for doctors as well as patients, as PEA is an endogenious fatty acid without any troublesome side-effects and easy to use to reduce pain, even together with other drugs.

Lipids like N-palmitoylethanolamine can act as signaling molecules, activating intracellular and membrane-associated receptors to regulate physiological functions. The signaling lipid PEA is known to activate intracellular, nuclear and membrane-associated receptors and regulate many physiological functions related to the inflammatory cascade, and thus is of high interest in the treatment of neuropathic, or gliopathic pain.
