LATUDA vs SECUADO
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.
SECUADO (asenapine) is an atypical antipsychotic with high affinity for serotonin 5-HT2A, 5-HT2C, 5-HT6, and 5-HT7 receptors, as well as dopamine D2, D3, and D4 receptors. It also exhibits moderate affinity for histamine H1 and alpha2-adrenergic receptors, and low affinity for alpha1 and muscarinic receptors. The therapeutic effect in schizophrenia and bipolar disorder is primarily mediated through antagonism at D2 and 5-HT2A 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).
Adults: 3.8 mg/24 hours applied transdermally once daily; initially 3.8 mg/24 hours, may titrate to 5.7 mg/24 hours, 7.6 mg/24 hours, or 11.4 mg/24 hours based on tolerability and efficacy. Maximum dose: 11.4 mg/24 hours.

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: 20-24 hours; steady-state achieved within 5 days.
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.
Primarily renal: 50-80% as unchanged drug; biliary/fecal: <15%.
