Pretreatment with the dopamine receptor blocker caused a faster decline in 3,4-methylenedioxypyrovalerone (MDPV)-induced locomotor activity. Data are presented as mean±SE (n=6–8 rats per treatment). A significant main effect of drug treatment was observed for locomotor activity (F3,24=11.8 p<0.0001; two-way analysis of variance (ANOVA) drug main factor × time repeated factor) and stereotypy (F3,24=8.7, p=0.0004; two-way ANOVA drug main factor × time repeated factor). *, MDPV 3.0 mg/kg significantly different from saline; •, Flup+MDPV significantly different from saline; ○, MDPV 3.0 mg/kg significantly different from Flup+MDPV (Sidak's multiple comparison post hoc test, p<0.05). Flup, cis-flupenthixol.
