We have previously shown that the neurosteroid pregnenolone sulfate (PS) inhibits the capsaicin receptor-mediated current in rat dorsal root ganglion neurons. Here, we examined the effect of intradermal injection of PS into the rat hindpaw on capsaicin-induced nociception. Results revealed that PS co-injected with capsaicin dose-dependently inhibited the capsaicin-induced nocifensive response. In contrast, injections of PS into one hindpaw and capsaicin into the contralateral hindpaw had no effect on the capsaicin-induced nocifensive response, suggesting that PS produced its effect locally but not systemically. Moreover, PS inhibition of the capsaicin-induced nocifensive response was not significantly reduced by a nonselective opioid receptor antagonist or by cannabinoid receptor antagonists, indicating that neither an opioid- nor a cannabinoid-dependent mechanism mediated the effect of PS. These data demonstrate that PS acts peripherally to attenuate capsaicin-induced nociception through an opioid- and cannabinoid-independent mechanism and suggest a new therapeutic potential for PS in pain management.
