In Vitro (S)-Amisulpride (Esamisulpride) displays high affinity binding at both D2 and D3 receptors and is approximately twice as potent as racamisulpride and 20–50 times more potent than (R)-amisulpride at these receptors[2]
In Vivo The (S)-amisulpride (10mg/kg, s.c.) stimulus is rapidly acquired and was shown to be dose-related, time dependent (effective between 30 and 120min) and stereoselective male C57BL/6 mice[1].
