The combination of M100907, a putative antipsychotic drug (APD) and serotonin (5-HT)2A antagonist, and the typical APD haloperidol, can enhance dopamine (DA) release in rat medial prefrontal cortex (mPFC), an effect which has been postulated to be of value to improve cognition and negative symptoms. The present study demonstrated that another putative APD and 5-HT2A/2C antagonist, SR46349-B (10 mg/kg, but not 1–3 mg/kg) alone, but not M100907 (0.1 and 3 mg/kg) alone, increased mPFC DA release… CONTINUE READING
