Neurotoxicology

Vincristine (VCR) peripheral neuropathy is a dose-limiting side effect. Several studies have shown that tropisetron, a 5-HT3 receptor antagonist, exerts anti-inflammatory and immunomodulatory properties. Current study was designed to investigate a suppressive effect of tropisetron on VCR-induced neuropathy and whether this effect exerts through the 5-HT3 receptor or not. ⋯ Moreover, pathological evidence confirmed the results obtained from other findings. But granisetron and mCPBG had no significant effect on the mentioned parameters. In conclusion, these studies demonstrate that tropisetron significantly suppressed VCR-induced neuropathy and could be a neuroprotective agent for prevention of VCR-induced neuropathy via a receptor-independent pathway.
