Preventive effect of aripiprazole once-monthly on relapse into mood episodes in bipolar disorder: A multicenter, one-year, retrospective, mirror image study

초록

Background: We conducted a one-year, retrospective, mirror-image study to investigate the clinical effectiveness and safety of aripiprazole once monthly (AOM) in patients with bipolar disorder (BD). We compared pretreatment conditions with outcomes after 12 months of AOM treatment. Methods: Seventy-five bipolar patients were recruited from 12 hospitals in Korea. We included 75 patients with BD who had received at least three AOM treatments from September 2019 to September 2022 and had accessible electronic medical record (EMRs) for the year before and after the baseline visit. Results: The overall number of mood episodes significantly decreased from a mean of 1.5 +/- 1.2 episodes preAOM to 0.5 +/- 1.2 episodes post-AOM. Manic episodes significantly decreased from 0.8 +/- 0.8 episodes preAOM to 0.2 +/- 0.5 episodes post-AOM, and depressive episodes significantly decreased from 0.5 +/- 0.8 episodes pre-AOM to 0.2 +/- 0.6 episodes post-AOM (p = 0.017). Moreover, the number of psychiatric medications and pills and the proportion of patients treated with complex polypharmacy were significantly decreased postAOM. Limitations: The small sample size was insufficient to fully represent the entire population of individuals with BD, and potential selection bias was introduced due to only including subjects who received AOM three or more times. Conclusion: The results of this study suggest that AOM can reduce mood episode relapse and may be clinically beneficial in the treatment of BD patients, potentially reducing issues associated with polypharmacy in some individuals.
