Either 5-HT2A antagonism or fast dissociation from D2 receptors may define an atypical antipsychotic. To have little or no motor symptoms from an antipsychotic, it is clear that D2 receptor binding in the striatum must be less than that caused by conventional antipsychotics. Pure 5-HT2A antagonism by itself does not result in robust antipsychotic actions. However, 5-HT2A antagonism can reduce D...

Although understanding of the pathophysiology of akathisia remains limited, it seems that a complex interaction of several neurotransmitter syste...
