Randomized Controlled Trial
A double-blind randomized placebo controlled study assessing safety, tolerability and efficacy of palmitoylethanolamide for symptoms of knee osteoarthritis.
Inflammopharmacology 2019 June
BACKGROUND: The aim of the study was to assess the safety, tolerability and efficacy of palmitoylethanolamide (PEA) when dosed at 300 mg and 600 mg per day on symptoms of knee osteoarthritis.
METHODS: This was a single site, comparative, double-blind placebo controlled study in adults with mild to moderate knee osteoarthritis with 111 participants randomized to receive 300 mg PEA, 600 mg PEA or placebo each day, in divided doses b.i.d, for 8 weeks. The primary outcome was the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC). The secondary outcomes were the Numerical Rating Scales (NRS) for pain, the Depression Anxiety Stress Scale (DASS), the Perceived Stress Scale (PSS), the Pittsburg Sleep Quality Index (PSQI), the Short Form Health Survey (SF-36), the use of rescue pain medication and clinical safety assessment.
RESULTS: There was a significant reduction in the total WOMAC score in the 300 mg PEA (p = 0.0372) and the 600 mg PEA (p = 0.0012) groups, the WOMAC pain score (300 mg PEA, p = 0.0074; 600 mg PEA, p = < 0.001), the WOMAC stiffness score (PEA 300 mg, p < 0.0490; 600 mg PEA, p = 0.001) and in the WOMAC function score in the 600 mg PEA group (p = 0.033) compared to placebo. The NRS pain evaluations for "worst pain" and "least pain" were significantly reduced in the 300 mg PEA group (p < 0.001, p = 0.005) and the 600 mg PEA group (p < 0.001, p < 0.001) compared to placebo. There was a significant reduction in anxiety (DASS) in both active treatment groups (300 mg PEA, p = 0.042; 600 mg PEA group (p = 0.043) compared to placebo. There were no changes in the clinical markers and the product was well tolerated.
CONCLUSIONS: The study demonstrated that palmitoylethanolamide may be a novel treatment for attenuating pain and reducing other associated symptoms of knee osteoarthritis. Further studies on the pharmacological basis of this anti-inflammatory effect are now required.
