Most of the clinically used antipsychotics display fairly high affinity for D3 receptors in vitro, they lack significant D3 receptor binding in vivo. They also do not occupy D3 receptors in schizophrenic patients at clinically-relevant doses, despite having significant and expected D2 receptor occupancy. The lack of in vivo D3 receptor occupancy of currently used antipsychotics may be due to their inability to displace endogenous DA from these sites; especially since DA has approximately 20- fold higher affinity for D3 vs D2 receptors and D3 (but not D2) receptors exist predominantly in a high affinity state for DA”
