Effects of intraplantar injection of various doses of olvanil and rimonabant (1 μg) on capsaicin-induced thermal hyperalgesia. Rats received intraplantar injection of olvanil (Olv; 0.1, 0.3 and 1 μg) or a combination of 0.3 μg olvanil/1 μg rimonabant or vehicle 15 min prior to capsaicin (Caps). Data are expressed as mean ± SEM of % PWL and analyzed using one way ANOVA test followed by Dunnett’s post-hoc, different treatments were compared to vehicle at 10 min after injection (*P < 0.05, n = 7 rats per group)
