Laboratory studyOther animals

Design
Laboratory study
Subjects
Male Sprague-Dawley rats with spinal nerve transection (neuropathic pain) or intra-articular monoiodoacetic acid (inflammatory pain)
Dose used in the study
PEA given by intraperitoneal and intra-articular injection; exact dose not stated in the abstract
Duration
Not stated in the abstract
What was measured
Mechanical and cold sensitivity (von Frey filaments, acetone test) and paw withdrawal responses

What the authors reported

Spinal nerve transection lowered the mechanical threshold and raised acetone-response frequency, but not cold-withdrawal frequency. PEA, by intraperitoneal and intra-articular injection, significantly reduced mechanical hyperalgesia from chronic inflammation, but did not reduce cold allodynia.

Limits of this study

Rat models of neuropathic and inflammatory pain; it cannot show effect in people. Funding and conflicts not stated in the abstract.
