Efficacy and tolerability of aripiprazole intramuscular as maintenance treatment in patients with paranoid schizophrenia

Abstract

IntroductionPatients suffering from paranoid schizophrenia, require long-term anti-psychotic treatment, which provide, in addition to adequate efficacy both positive and negative symptoms, a good safety and tolerability profile that would ensure adequate adherence to prevent relapse.ObjectivesTo analyze the efficacy, tolerability and therapeutic adherence over a year after the introduction of aripiprazole depot in patients diagnosed with paranoid schizophrenia previously treated with other oral or depot anti-psychotics [1,2,3].MethodsOne-year prospective longitudinal study with a sample size of 23 patients diagnosed with schizophrenia in outpatient treatment. Study variables (baseline, 6 and 12 months): Brief Psychiatric Rating Scale (BPRS), clinical global impression (CGI), mean dose of aripiprazole depot, previous treatments, adherence, relapse rate, prolactin levels, sexual dysfunction, BMIs.ResultsTwenty-three patients (71% men, 29% women) diagnosed with paranoid schizophrenia were identified. Improvement was obtained in the different study variables with statistically significant difference (P ≤ 0.05).ConclusionsFollowing the introduction of aripiprazole depot in patients diagnosed with schizophrenia previously treated with other oral or depot anti-psychotics in our study, we conclude that maintaining therapeutic efficacy a better tolerability and safety profile, better therapeutic adherence and consequently lower relapse rate were achieved.Disclosure of interestThe authors have not supplied their declaration of competing interest.
