FANAPT vs SECUADO
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
FANAPT (iloperidone) is an atypical antipsychotic that exhibits high affinity for serotonin 5-HT2A and dopamine D2 receptors, with additional antagonism at alpha1-adrenergic, alpha2-adrenergic, and histamine H1 receptors. The therapeutic efficacy is primarily attributed to combined 5-HT2A and D2 receptor antagonism.
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.
12-24 mg orally once daily, titrated from 1 mg twice daily on day 1, 2 mg twice daily on day 2, 4 mg twice daily on day 3, 6 mg twice daily on day 4, 8 mg twice daily on day 5, then 10 mg twice daily on day 6 and 7, followed by 12 mg once daily on day 8. Maximum dose: 24 mg/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 26 hours (range 22-30 hours) for the sum of parent drug and active metabolites (P95, P88, and P86); steady-state achieved within 4-5 days.
Terminal elimination half-life: 20-24 hours; steady-state achieved within 5 days.
Renal (approximately 80% as metabolites, <1% as parent drug) and fecal (approximately 20% as metabolites).
Primarily renal: 50-80% as unchanged drug; biliary/fecal: <15%.
