LURASIDONE HYDROCHLORIDE vs SECUADO
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Lurasidone is an atypical antipsychotic that acts as a full antagonist at D2 and 5-HT2A receptors, with high affinity for 5-HT7 and 5-HT1A receptors, moderate affinity for alpha2C and alpha2A adrenergic receptors, and no appreciable affinity for H1, M1, or alpha1 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 mg once daily; maximum 80 mg per day.
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 18 hours (range 14–24 hours), supporting once-daily dosing.
Terminal elimination half-life: 20-24 hours; steady-state achieved within 5 days.
Approximately 80% of total radioactivity recovered in feces (67% as metabolites, 9% as unchanged drug) and 19% in urine (mostly metabolites); less than 1% excreted as unchanged parent in urine.
Primarily renal: 50-80% as unchanged drug; biliary/fecal: <15%.
