Abstract

(±)-([1-(2,5-Dimethoxy-4-iodophenyl)-aminopropane]-hydrochloride) (DOI) (2.5 mg/kg), a 5-HT2A/2C agonist, significantly potentiated D-amphetamine (AMPH) (1 mg/kg)-induced dopamine (DA) release in rat medial prefrontal cortex (mPFC) and nucleus accumbens (NAC). This effect of DOI was completely prevented by M100907 (1 mg/kg), a selective 5-HT2A antagonist, which by itself had no effect on basal and AMPH-induced DA release in either region. Thus, 5-HT2A receptor agonism potentiates AMPH-induced DA release in the mPFC and NAC.
