Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Paliperidone is the major active metabolite of risperidone. It is a benzisoxazole derivative antipsychotic that antagonizes central dopamine type 2 (D2) and serotonin type 2 (5-HT2A) receptors. It also antagonizes alpha-1 and alpha-2 adrenergic, and histamine H1 receptors.
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.
Administered intramuscularly (gluteal or deltoid) at 3-month intervals. Starting dose: 350 mg, 525 mg, or 700 mg based on prior stabilization dose of oral paliperidone or INVEGA SUSTENNA. Maximum dose: 700 mg.
40 mg orally once daily initially, titrated to 80-160 mg once daily; maximum 160 mg/day. Administer with food (at least 350 calories).

Terminal elimination half-life: 3 to 6 months (mean 118 days) due to slow dissolution from intramuscular depot; clinical context: steady state reached after 3 injections every 3 months.
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.
Renal: 59-80% as unchanged drug and metabolites; fecal: 6-15%; biliary: minimal.
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.
