LUMATEPERONE TOSYLATE vs RISPERIDONE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
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.
Risperidone is an atypical antipsychotic that antagonizes dopamine D2 receptors and serotonin 5-HT2A receptors. It also has moderate affinity for alpha1-adrenergic and H1-histaminergic receptors, and low affinity for muscarinic receptors.
42 mg orally once daily
Initial 2 mg orally once daily, titrated to target dose of 4-6 mg orally once daily (or divided twice daily); maximum 16 mg/day. Alternatively, long-acting IM injection: 25 mg IM every 2 weeks.

Clinical Note
moderateRisperidone + Fluticasone propionate
"The risk or severity of adverse effects can be increased when Risperidone is combined with Fluticasone propionate."
Clinical Note
moderateRisperidone + Methylphenidate
"The risk or severity of adverse effects can be increased when Risperidone is combined with Methylphenidate."
Clinical Note
moderateRisperidone + Quinagolide
"The therapeutic efficacy of Quinagolide can be decreased when used in combination with Risperidone."
Clinical Note
moderateTerminal elimination half-life is approximately 24-29 hours, allowing once-daily dosing. Steady-state reached in about 5 days.
Risperidone: 3 hours (CYP2D6 extensive metabolizers), 20 hours (poor metabolizers); active metabolite 9-hydroxyrisperidone: 21-30 hours; steady-state reached in 5-6 days
Approximately 60% excreted in urine as metabolites (unchanged drug negligible) and 30% in feces via biliary elimination.
Renal (70% as metabolites, 14% as parent drug) and fecal (14%)
