Design
Laboratory study
Subjects
Rats with osteoarthritis induced by monoiodoacetate; numbers not stated in the abstract
Dose used in the study
No palmitoylethanolamide was given; the NAAA inhibitor F215 by intra-articular and intraperitoneal injection, doses not stated
Duration
Not stated in the abstract
What was measured
NAAA expression and palmitoylethanolamide levels in synovium and lumbar spinal cord; cartilage damage, synovial inflammation and pain; the effect of the PPAR-alpha antagonist MK886

What the authors reported

Osteoarthritic rats had higher NAAA and lower palmitoylethanolamide in synovium and spinal cord. F215 protected against cartilage damage and synovial inflammation by raising joint PEA levels and normalising spinal PEA, and reduced osteoarthritic pain. MK886 blocked these effects.

Limits of this study

A rat model using an enzyme inhibitor that raises the body's own PEA, not PEA supplementation; it cannot show effect in people. Doses and numbers are not in the abstract. Funding and conflicts not stated in the abstract.
