Potent and selective 5-HT2A antagonist (IC50 values are 5.8 and 120 and >100 nM for 5-HT2A, 5-HT2B and 5-HT2C, respectively). Attenuates cocaine-induced hyperactivity. Increases dopamine (DA) release in rat medial prefrontal cortex (mPFC); potentiates haloperidol-induced DA release in the mPFC and nucleus accumbens.

We assessed the effect of the 5-HT2A antagonist, SR-46349B (eplivanserin hemifumarate; 0.5 mg/kg, s.c.), on MDMA (ecstasy)-induced locomotion and dorsal striatal single-unit electrophysiology. SR-46349B blocked nearly all MDMA-induced striatal excitations, which paralleled its significant attenuation of MDMA-induced locomotor activation (shown in figure).
