Effect of methiothepin (5-HT1/6/7 receptor antagonist), ketanserin (5-HT2A receptor antagonist), and ondansetron (5-HT3 receptor antagonist) pre-treatment on cardamonin against mechanical allodynia of CCI-induced neuropathic pain mice were evaluated using von-Frey filament test. Data were presented as mean ± SEM (n = 6). The caret, hash, and asterisks denote the significance levels (one-way ANOVA, followed by Tukey’s post hoc test, ^^
