TOVALT ODT vs VRAYLAR
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
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.
Cariprazine is a partial agonist at dopamine D2 and D3 receptors and serotonin 5-HT1A receptors, and an antagonist at 5-HT2A and 5-HT2B receptors. Its antipsychotic activity is primarily mediated via D2 and D3 receptor partial agonism.
20 mg sublingually as needed for BTP, with a minimum interval of 2 hours between doses; maximum 4 doses per day.
1.5 mg orally once daily with food, then titrate to 3 mg on day 4, then to 6 mg on day 8; maximum dose 6 mg/day.

Terminal elimination half-life approximately 40–60 hours after multiple dosing; clinical context: reaches steady-state after 2–3 weeks.
The terminal elimination half-life of cariprazine is 2-4 days, and for its active metabolites (desmethylcariprazine and didesmethylcariprazine) it is 1-3 weeks. This long half-life results in steady-state concentrations being reached after 3-4 weeks of daily dosing, contributing to prolonged clinical effects and a need for slow titration.
Primarily hepatic metabolism; 70–80% as inactive metabolites in urine, <5% unchanged in urine, 20–30% fecal.
Cariprazine and its active metabolites are primarily eliminated via hepatic metabolism and subsequent biliary/fecal excretion. Approximately 20% of the dose is recovered in urine, mainly as inactive metabolites, while about 80% is recovered in feces, largely as unchanged cariprazine and its active metabolites.
