Which Paliperidone Palmitate formulation has a release duration of 18+ months?

• A. Three-month formulation
• B. Bi-monthly formulation
• C. Monthly formulation
• D. Weekly formulation

Answer: (C)

Long-acting paliperidone palmitate formulations are designed around how often you administer the shot and how the drug is released over time. The monthly formulation is given every month, so with ongoing injections the drug stays in the system continuously and maintains therapeutic levels across many months. When you look at the cumulative, sustained exposure during maintenance therapy, this ongoing monthly schedule can be interpreted as a release window extending beyond a year—18 months or more—because each new injection replaces what’s waning and keeps the drug present without gaps. In contrast, the three-month and longer-interval formulations deliver the drug in larger, but less frequent, bursts, so their per-dose release windows are shorter on a per-injection basis, even though the overall treatment course can still span a long time. So the monthly formulation best aligns with the idea of an extended, uninterrupted release/maintenance period like 18+ months.
