Ziprasidone hydrochloride monohydrate is an atypical antipsychotic that displays combined SR-2A and D2DR inhibition. Ziprasidone displays high affinity at SR-2A receptors with a SR-2A/D2DR affinity ratio greater than any other clinically available atypical antipsychotics (pKi values are 9.38, 8.88, 8.69, 8.47, 8.32, 8.14, 7.98, 7.49, 7.33 and 6.28 for SR-2A, 5-HT2C, 5-HT1D, 5-HT1A, D2DR, D3, α1, D4, H1 and D1 receptors respectively).
