Abstract

Objective: This study was done for collection of real world data of Aripiprazole Once Monthly (AOM) in patients with schizophrenia. Methods: The observation was up to 12 months from the first use of AOM in patients with antipsychotic polypharmacy (APpoly)/other long acting injectable antipsychotics (LAIs) for treatment of schizophrenia in daily practice. Demographics and available clinical information such as The Positive and Negative Syndrome Scale (PANSS) and Clinical Global Impression-severity (CGI-S) scores were retrieved from the electronic medical record (EMR). Adverse events were also noted as described in EMR. Results: Eighteen patients were found to be switched from APpoly/LAIs. Mean numbers of previous APs treatment failure and immediate prior APs were 2.2 and 2.4, respectively; most commonly used APs before AOM were aripiprazole, blonanserin, quetiapine, and risperidone. Mean number of combined APs before AOM significantly decreased from 2.4 use to 0.7 at month 12 (p < 0.0001). The PANSS total (71.7 to 62.1, p = 0.000) and CGI-S (3.4 to 3.1, p = 0.008) scores were also significantly decreased from baseline (first use of AOM) to month 12, respectively. Other various psychotropics including anxiolytics were also significantly and substantially decreased at some point from baseline throughout the observation period as well. Mild hand tremor and akathisia were developed in 3 patients. Conclusion: The present observation study clearly confirmed the use of AOM should be also effective and tolerable treatment option for patients with APpoly/LAIs in the real world practice. Subsequent, adequately-powered, and well-controlled clinical trials are warranted in near future.
