LURASIDONE HYDROCHLORIDE vs UZEDY
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Lurasidone is an atypical antipsychotic that acts as a full antagonist at D2 and 5-HT2A receptors, with high affinity for 5-HT7 and 5-HT1A receptors, moderate affinity for alpha2C and alpha2A adrenergic receptors, and no appreciable affinity for H1, M1, or alpha1 receptors.
Atypical antipsychotic; antagonist at dopamine D2 and serotonin 5-HT1A/5-HT2A receptors; partial agonist at serotonin 5-HT1A receptors
40 mg orally once daily initially, titrated to 80 mg once daily; maximum 80 mg per day.
UZEDY (risperidone) extended-release injectable suspension: 75 mg, 100 mg, 150 mg, or 200 mg IM gluteal injection every 2 weeks after a single oral dose of 2 mg risperidone for 2 days; or 25 mg, 50 mg, 75 mg, 100 mg, 125 mg, or 150 mg IM every 4 weeks after oral overlap for 2 days. Oral risperidone may be omitted if patient is stable on oral risperidone 2 mg/day.

Terminal elimination half-life is approximately 18 hours (range 14–24 hours), supporting once-daily dosing.
Terminal half-life approximately 30 days (range 23–37 days) after subcutaneous injection, supporting monthly dosing.
Approximately 80% of total radioactivity recovered in feces (67% as metabolites, 9% as unchanged drug) and 19% in urine (mostly metabolites); less than 1% excreted as unchanged parent in urine.
Primarily renal: 80% as metabolites, 1% unchanged. Biliary/fecal: 20%.
