ARISTADA vs TOVALT ODT
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Aripiprazole lauroxil is a prodrug of aripiprazole, a partial agonist at dopamine D2 and serotonin 5-HT1A receptors and an antagonist at 5-HT2A receptors. The mechanism of action in schizophrenia and bipolar I disorder is thought to be mediated through these receptor interactions.
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.
Initial dose: 675 mg intramuscularly every 4 weeks for the first 2 doses, then maintenance dose of 882 mg intramuscularly every 4 weeks. Alternatively, 1064 mg intramuscularly every 6 weeks after appropriate initiation.
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 of aripiprazole lauroxil (the prodrug in ARISTADA) is approximately 54 days (range 29-74 days) after IM injection, allowing monthly dosing.
Terminal elimination half-life approximately 40–60 hours after multiple dosing; clinical context: reaches steady-state after 2–3 weeks.
Primarily renally excreted (approximately 60% as metabolites, <1% unchanged). Fecal elimination accounts for about 20%.
Primarily hepatic metabolism; 70–80% as inactive metabolites in urine, <5% unchanged in urine, 20–30% fecal.
