ASENAPINE MALEATE vs SECUADO
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Asenapine is an atypical antipsychotic with high affinity for serotonin 5-HT2A, 5-HT2C, 5-HT1A, and dopamine D2 receptors. It also antagonizes alpha1/alpha2-adrenergic and histamine H1 receptors, with moderate affinity for D3 and D4 receptors. The therapeutic effect in schizophrenia and bipolar disorder is primarily mediated through 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.
Sublingual: 5-10 mg twice daily; initial dose 5 mg twice daily, max 10 mg twice daily.
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 24 hours. Steady-state is achieved within 3 days. The half-life allows for twice-daily dosing.
Terminal elimination half-life: 20-24 hours; steady-state achieved within 5 days.
Approximately 50% of the dose is excreted renally, and 40% fecally. After oral administration, about 50% appears in urine (as unchanged drug and metabolites) and 40% in feces.
Primarily renal: 50-80% as unchanged drug; biliary/fecal: <15%.
