The anti-hyperalgesic actions of the cannabinoid anandamide and the putative CB2 receptor agonist palmitoylethanolamide in visceral and somatic inflammatory pain
Abstract
This study assessed the effects of two N-acylethanolamides in established rat models of visceral and somatic inflammatory pain. (1) The therapeutic effects of the cannabinoid anandamide and the putative CB2 agonist palmitoylethanolamide were tested in a model of persistent visceral pain (turpentine inflammation of the urinary bladder). Both anandamide (at a dose of 25 mg/kg) and palmitoylethanolamide (at doses of 10-30 mg/kg) were able to attenuate the viscero-visceral hyper-reflexia (VVH) induced by inflammation of the urinary bladder. (2) The effects of the same compounds on the behavioural response to subcutaneous formalin injection were assessed. The characteristic biphasic response was observed in control animals. Anandamide (dose range 5-25 mg/kg) and palmitoylethanolamide (dose range 5-10 mg/kg) both reduced the second phase of the response. The results confirm the analgesic potential of endogenous ligands at cannabinoid receptor sites. The anti-nociceptive effect of the putative CB2 receptor agonist, palmitoylethanolamide, is particularly interesting since it is believed to be a peripherally mediated effect. This observation might be exploited to separate central psychotropic effects from peripheral analgesic actions of the cannabinoids, under inflammatory conditions.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
