NCIt definition : The hydrochloride salt form of ziprasidone, a benzothiazolylpiperazine derivative
and an atypical antipsychotic agent with an antischizophrenic property. Ziprasidone
hydrochloride functions as an antagonist at the dopamine D2 and serotonin 5-HT2A and
5-HT1D receptors, and as an agonist at the 5-HT1A receptor. Ziprasidone hydrochloride
also inhibits synaptic reuptake of serotonin and norepinephrine. The mechanism of
action by which ziprasidone hydrochloride exerts its antischizophrenic effect is unknown
but is potentially mediated through a combination of dopamine D2 and serotonin 5-HT2
antagonism. This agent also has antagonistic activity against histamine H1 and alpha-1-adrenergic
receptors.;
