Palmitoyl ethanol amide (PEA) is an endogenous substance that plays a role in neuropathic pain. In this article, we evaluated both the safety and the efficacy of ultramicronized PEA (um-PEA) in the treatment of low back pain related to nonsurgical lumbar radiculopathy. In this prospective single-blind study, patients with low back pain related to nonsurgical lumbar radiculopathy received the fixed combination acetaminophen/codeine (500 mg + 30 mg/d) for 7 days, and then it was stopped and changed to um-PEA (1200 mg/d) for 30 days. Patients without an improvement in pain or disability started a second cycle of treatment with um-PEA (600 mg/d in tablets) for 30 days and then acetaminophen/codeine for 30 days. A total of 155 patients were included in the analysis. After the first cycle of treatment we recorded an improvement of pain in all patients with mild pain (visual analog scale score from 3-4 to 1) and in 75% of the patients with moderate pain (visual analog scale score from 5-6 to 2). After the second cycle, we recorded an improvement of pain and disability in all patients with moderate pain (P < .01), but in 26% of patients with severe pain we did not record any improvement in disability (P > .05). In conclusion we evaluated the role of um-PEA in patients with lumbar radiculopathy with a long-term follow-up (24 months) and put in evidence the effectiveness and the safety of this formulation in patients with mild and moderate pain.
