90-120 mg q4 weeks is the dosing for which product?

• A. Paliperidone palmitate 3-monthly
• B. Aripiprazole Maintena
• C. Risperidone (Risperdal Consta)
• D. Risperidone RBP-7000 (Perseris)

Answer: (D)

The key idea here is matching the dosing interval and amount to the specific long-acting antipsychotic. A monthly subcutaneous injection in a fixed monthly dose of 90 mg or 120 mg is characteristic of Risperidone RBP-7000, brand Perseris. That product is designed for monthly administration, hence 90-120 mg every 4 weeks. Other options use different schedules: Risperidone Consta is an intramuscular injection given every 2 weeks; Aripiprazole Maintena is monthly as well but at a different dose range (typically around 300–400 mg); Paliperidone palmitate 3-monthly (Invega Trinza) is every 3 months. So the 90–120 mg every 4 weeks pattern fits Perseris best.
