FANAPT vs TOVALT ODT
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.
Tovalt ODT (selegiline) is a selective, irreversible inhibitor of monoamine oxidase type B (MAO-B). At therapeutic doses, it inhibits MAO-B more selectively than MAO-A, leading to increased levels of dopamine in the brain.
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.
20 mg sublingually as needed for BTP, with a minimum interval of 2 hours between doses; maximum 4 doses per day.

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 approximately 40–60 hours after multiple dosing; clinical context: reaches steady-state after 2–3 weeks.
Renal (approximately 80% as metabolites, <1% as parent drug) and fecal (approximately 20% as metabolites).
Primarily hepatic metabolism; 70–80% as inactive metabolites in urine, <5% unchanged in urine, 20–30% fecal.
