ARISTADA vs LUMATEPERONE TOSYLATE
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.
Lumateperone tosylate is an atypical antipsychotic with a unique mechanism of action involving antagonism of serotonin 5-HT2A receptors, partial agonism of serotonin 5-HT1A receptors, and antagonism of dopamine D2 receptors; it also modulates glutamate via phosphorylation of GluN2B subunits and inhibits serotonin reuptake.
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.

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 is approximately 24-29 hours, allowing once-daily dosing. Steady-state reached in about 5 days.
Primarily renally excreted (approximately 60% as metabolites, <1% unchanged). Fecal elimination accounts for about 20%.
Approximately 60% excreted in urine as metabolites (unchanged drug negligible) and 30% in feces via biliary elimination.
