INVEGA TRINZA vs PALIPERIDONE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Paliperidone is the major active metabolite of risperidone. It is a benzisoxazole derivative antipsychotic that antagonizes central dopamine type 2 (D2) and serotonin type 2 (5-HT2A) receptors. It also antagonizes alpha-1 and alpha-2 adrenergic, and histamine H1 receptors.
Paliperidone is an atypical antipsychotic that exerts its effects primarily through antagonism of central dopamine D2 receptors and serotonin 5-HT2A receptors. It also antagonizes alpha-1 and alpha-2 adrenergic receptors, and H1 histaminergic receptors. Paliperidone is the major active metabolite of risperidone.
Administered intramuscularly (gluteal or deltoid) at 3-month intervals. Starting dose: 350 mg, 525 mg, or 700 mg based on prior stabilization dose of oral paliperidone or INVEGA SUSTENNA. Maximum dose: 700 mg.
6 mg orally once daily, with dose adjustments in 3 mg increments at intervals of 5 days or more; usual effective range 3-12 mg/day.

Terminal elimination half-life: 3 to 6 months (mean 118 days) due to slow dissolution from intramuscular depot; clinical context: steady state reached after 3 injections every 3 months.
Approximately 23 hours for the extended-release oral formulation; provides steady trough concentrations with once-daily dosing
Renal: 59-80% as unchanged drug and metabolites; fecal: 6-15%; biliary: minimal.
Renal (approximately 80% as unchanged drug and glucuronide conjugate), biliary/fecal (approximately 11%)
