INVEGA HAFYERA vs LURASIDONE HYDROCHLORIDE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Paliperidone palmitate is an atypical antipsychotic that antagonizes D2 and 5-HT2A receptors, with additional antagonism at alpha2, alpha1, and H1 receptors.
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.
INVEGA HAFYERA (paliperidone palmitate) is dosed once weekly via intramuscular injection in the gluteal or deltoid muscle. The recommended starting dose is 1,092 mg (deltoid or gluteal) or 1,560 mg (gluteal only) on treatment day 1 and day 8, both given in the deltoid muscle. Subsequent maintenance doses are administered once monthly. Note: INVEGA HAFYERA is only for once-weekly administration; once-monthly formulations (INVEGA SUSTENNA) are also available.
40 mg orally once daily initially, titrated to 80 mg once daily; maximum 80 mg per day.

Terminal elimination half-life is 25-49 days (mean ~36 days) due to slow dissolution from intramuscular depot. Steady-state reached after 4-5 monthly injections.
Terminal elimination half-life is approximately 18 hours (range 14–24 hours), supporting once-daily dosing.
Primarily renal: 59% of paliperidone excreted unchanged in urine; 32% as metabolites; 6-12% fecal. Biliary excretion is minimal.
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.
