Abstract

Many reports have shown the efficacy of cannabinoid agonists in chronic pain, whereas no report exists concerning the potential effect of cannabinoid antagonists following prolonged treatment. We tested the effects of repeated administration of the selective cannabinoid receptor type 1 (CB1) antagonist, SR141716 (rimonabant), in rats with chronic constriction injury of the sciatic nerve (CCI), an animal model of neuropathic pain. The repeated oral administration of SR141716 (1, 3 and 10 mg/kg, once a day for 1 week, from day 7 after the injury) dose dependently attenuated both thermal and mechanical hyperalgesia. A similar effect was observed in CCI wild-type mice, whereas SR141716 was unable to elicit pain relief in CB1 knockout mice, suggesting CB1 receptors involvement in the SR141716-induced antihyperalgesia. The antihyperalgesic activity of SR141716 was associated with a significant reduction of several pro-inflammatory and pro-nociceptive mediators such as tumor necrosis factor alpha (TNFalpha), prostaglandin-E2 (PGE2), lipoperoxide and nitric oxide (NO) levels. The histological analysis of sciatic nerve sections showed a marked degeneration of myelinated fibers in CCI rats, which was substantially reduced after repeated administration of SR141716. This suggests that the compound may favour myelin repair and consequently promote long-lasting functional recovery. This was confirmed by the maintenance of recovery for at least four weeks after treatment discontinuation. In conclusion, the present findings suggest that SR141716 is effective not only in alleviating neuropathic pain but also in favouring the nerve myelin repair.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • SR141716 administered chronically suppresses thermal and mechanical hyperalgesia in both rats and CB1+/+ mice, while failing to produce an effect in CB1-/- mice.

    “However, SR141716 (p.o.), administered chronically, suppresses thermal and mechanical hyperalgesia in both rats and CB1+/+ mice, while failing to produce an effect in CB1-/- mice. 43”

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.
