INVEGA TRINZA vs TOVALT ODT
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.
Tovalt ODT (selegiline) is a selective, irreversible inhibitor of monoamine oxidase type B (MAO-B). At therapeutic doses, it inhibits MAO-B more selectively than MAO-A, leading to increased levels of dopamine in the brain.
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.
20 mg sublingually as needed for BTP, with a minimum interval of 2 hours between doses; maximum 4 doses per 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.
Terminal elimination half-life approximately 40–60 hours after multiple dosing; clinical context: reaches steady-state after 2–3 weeks.
Renal: 59-80% as unchanged drug and metabolites; fecal: 6-15%; biliary: minimal.
Primarily hepatic metabolism; 70–80% as inactive metabolites in urine, <5% unchanged in urine, 20–30% fecal.
