Abstract
Introduction: Long-acting injectable (LAI) antipsychotic drugs are developed to reduce daily intake need and to overcome treatment non-adherence. Aripiprazole IM depot refers to two long-acting aripiprazole formulations, once monthly monohydrate (AOM) and aripiprazole lauroxil. AOM has been approved for schizophrenia since 2012 and for bipolar disorder since 2017. Aripiprazole lauroxil is approved for schizophrenia, not for bipolar disorder.Areas covered: To assess the effect of AOM in bipolar disorder, the authors searched PubMed and ClinicalTrials.gov for randomized trials using AOM in patients with bipolar disorder. Included were four studies covering efficacy, functioning, quality of life, and safety/tolerability. Studies lasted 12 months.Expert opinion: AOM reduced symptoms of patients with bipolar disorder and a manic episode, increased functioning and quality of life, and protected from recurrence of manic episodes. It proved to be safe/tolerable, with only akathisia occurring in ≥10% of cases and more frequently than with placebo. However, there were only 143 patients receiving AOM in the considered studies. Included studies were backed in their conclusions by other literature, but they come from 2017-2018. No studies are expected or planned in the near future. Aripiprazole lauroxil has not applied for approval in bipolar disorder and there is no sign it will.
