Review
Subjects
Eight clinical trials in sciatic pain and carpal tunnel syndrome, 1,366 patients in total, plus preclinical nerve-compression models
Dose used in the study
300 to 1,200 mg PEA a day across the trials
Duration
3 weeks to 2 months in the trials reviewed
What was measured
Narrative summary of pain scores, disability and adverse events; post hoc number needed to treat from the Guida 2010 data

What the authors reported

PEA reduced pain in each trial reviewed, including the 636-patient Guida trial (VAS 7.1 to 2.1 on 600 mg versus 6.6 to 4.6 on placebo), a 111-patient replication by Canteri, and several open-label carpal tunnel and sciatica studies. No drug interactions or troublesome side effects were reported.

Limits of this study

Narrative review, not systematic; no risk-of-bias assessment. Several included studies were conference abstracts or Italian-language reports. The authors run a neuropathic pain clinic that prescribes PEA. The NNT of 1.5 is their own post hoc calculation.
