Aripiprazole vs Risperidone for the acute-phase treatment of first-episode psychosis: a 6-week randomized, flexible-dose, open-label clinical trial

Abstract: Aripiprazole vs Risperidone for the acute-phase treatment of first-episode psychosis: A 6-week randomized, flexible-dose, open-label clinical trial Selecting the first antipsychotic agent for the acute phase of a first episode of psychosis (FEP) is a critical task that may impact on the long-term outcome. Despite that, there is a lack of research comparing head-to-head different second-generation antipsychotics at this stage. The aim of this study was to compare the effectiveness of aripiprazole and risperidone in the treatment of the acute phase after a FEP. For that purpose, from February 2011 to October 2018, a prospective, randomized, open-label study was undertaken. Two hundred-sixty-six first-episode, drug-naïve patients were randomly assigned to aripiprazole (n = 136), or risperidone (n = 130) and followed-up for 6-weeks. The primary effectiveness measure was all-cause treatment discontinuation. In addition, an analysis based on intention-to-treat principle was conducted to assess clinical efficacy. The overall dropout rate at 6-week reached 19.5%. Effectiveness measures were similar between both treatment groups as treatment discontinuation rates (?2 = 1.863; p = 0.172) and mean time until all-cause discontinuation (log rank = 1.421; p = 0.233) showed no statistically significant differences. In terms of clinical efficacy, risperidone proved a statistically significant better performance according to BPRS mean change between baseline and 6-week total score (t = 3.187; p = 0.002). Patients under risperidone treatment were significantly more likely to suffer sex-related adverse events. In conclusion, no differences regarding effectiveness were found between aripiprazole and risperidone for the acute-phase treatment of FEP. Despite the importance of efficacy during this phase of treatment, selecting the most effective treatment for the long-term outcome, requires addressing safety and patient ?s preferences
