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.
Paliperidone is an atypical antipsychotic with high affinity for serotonin 5-HT2A and dopamine D2 receptors. It also blocks alpha-2 adrenergic and H1 histaminergic receptors.
40 mg orally once daily initially, titrated to 80-160 mg once daily; maximum 160 mg/day. Administer with food (at least 350 calories).
Paliperidone palmitate is administered intramuscularly. Initial dose: 150 mg eq. on day 1 and 100 mg eq. on day 8, both in the deltoid muscle. Maintenance dose: 75 mg eq. monthly (range 25–150 mg eq.) administered in the deltoid or gluteal muscle.

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: 25-49 days (mean ~30 days) for IM injection; allows monthly 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.
Renal: 80% as unchanged drug and metabolites; fecal: 11%
