From the Guidelines

For patients transitioning from a monthly to an every two month maintenance regimen of Maintena (Aripiprazole), the recommended approach is to continue the same monthly dose for at least three months before switching to the two-month regimen, then double the dose and administer it every two months, as this maintains therapeutic blood levels of aripiprazole throughout the extended interval 1. When considering this transition, it's crucial to ensure the patient is stable on the monthly regimen. The dosing strategy for the transition involves doubling the monthly dose for administration every two months. For instance, a patient stable on 400 mg monthly would transition to 800 mg every two months, and a patient on 300 mg monthly would receive 600 mg every two months. The timing of the first two-month dose should coincide with the next scheduled monthly injection, ensuring continuous therapeutic coverage. Key points to consider during this transition include:

  • Monitoring patients for any changes in symptom control or the emergence of side effects, although the safety profile is generally consistent between the two regimens 1.
  • Ensuring the patient's stability on the monthly regimen before making the switch to minimize potential risks.
  • Understanding that the two-month formulation contains the same medication as the monthly formulation but with different release characteristics, allowing for the extended duration while maintaining efficacy. Given the information from recent studies, such as those discussed in the context of antipsychotic polypharmacy and monotherapy transitions 1, the approach to transitioning from a monthly to an every two month regimen of Maintena prioritizes maintaining therapeutic efficacy while minimizing potential side effects and ensuring patient stability.

From the Research

Transitioning from Monthly to Every Two Month Maintenance Regimen of Maintena (Aripiprazole)

  • The recommended dosing regimen for a patient transitioning from a monthly to an every two month maintenance regimen of Maintena (Aripiprazole) is not directly addressed in the provided studies 2, 3, 4, 5, 6.
  • However, a study on aripiprazole once-monthly as maintenance treatment for bipolar I disorder found that aripiprazole once-monthly 400 mg was safe, effective, and well tolerated for long-term maintenance treatment 6.
  • Another study compared the persistence and adherence to treatment associated with use of second-generation antipsychotic long-acting injectable medications, including aripiprazole monohydrate, and found that patients on paliperidone palmitate 3-monthly treatment showed comparatively longer persistence and better adherence 4.
  • It is worth noting that the provided studies do not offer a clear guideline for transitioning from a monthly to an every two month maintenance regimen of Maintena (Aripiprazole), and the decision to transition should be made on a case-by-case basis, taking into account the individual patient's response to treatment and medical history.

Key Considerations

  • When considering a transition from a monthly to an every two month maintenance regimen, it is essential to monitor the patient's response to treatment and adjust the dosing regimen as needed 6.
  • The patient's medical history, including any previous experience with antipsychotic medications, should be taken into account when making decisions about treatment regimens 4.
  • The potential benefits and risks of transitioning to an every two month maintenance regimen, including the potential for reduced hospitalizations and increased focus on functional recovery, should be carefully considered 4.
