LATUDA vs ZIPRASIDONE MESYLATE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Lurasidone is an atypical antipsychotic with high affinity for dopamine D2, serotonin 5-HT2A, and serotonin 5-HT7 receptors, and moderate affinity for serotonin 5-HT1A receptors. It acts as an antagonist at D2 and 5-HT2A receptors, and as a partial agonist at 5-HT1A receptors. The exact mechanism of action in schizophrenia and bipolar depression is unknown but is thought to involve modulation of these receptors.
Ziprasidone mesylate is an atypical antipsychotic with high affinity for serotonin 5-HT2A and dopamine D2 receptors. It also antagonizes 5-HT1D, 5-HT2C, and alpha1-adrenergic receptors, and inhibits serotonin and norepinephrine reuptake.
40 mg orally once daily initially, titrated to 80-160 mg once daily; maximum 160 mg/day. Administer with food (at least 350 calories).
20 mg intramuscularly (IM) as needed, not to exceed 40 mg/day; oral: 20 mg twice daily with food, titrated up to 80 mg twice daily. Maximum: 160 mg/day oral.

Terminal elimination half-life is approximately 20–40 hours (mean about 29 hours) in adults, supporting once-daily dosing. Steady-state is reached within 7 days.
Terminal elimination half-life is approximately 2.2 hours (range 1.4–3.6 h) for the mesylate salt; clinical context: requires twice-daily dosing.
Approximately 80% of the dose is eliminated in feces (mostly as unchanged drug and metabolites) and about 10% in urine. Less than 2% is excreted as unchanged lurasidone in urine.
Approximately 20% renal, 80% fecal/biliary. Unchanged drug accounts for <1% of renal excretion.
