Brief summary
This study attempts to observe the effectiveness and safety of aripiprazole in hospitalized patients with acute schizophrenia episode, and to compare the different drug regimens that may be involved in order to clarify the characteristics of the population for taking aripiprazole and provide reference for clinical rational drug use.
Detailed description
The control of acute schizophrenia effectively and rapidly will build up the confidence of patients on treatments. These early effects may influence the long-term compliance and prognosis of patients. Aripiprazole is an important drug in first line treatment of schizophrenia. However, at present in China, the application of aripiprazole in some patients with acute schizophrenia is not appropriate, leading to poor control of the positive symptoms of the acute phase. The purpose of this single-arm, open-label trial is to study the situation of the use of aripiprazole in hospitalized patients with acute schizophrenia episode, and to compare the different drug regimens that may be involved in order to supply important information for optimizing treatment strategies of hospitalized patients characterized by positive symptom. The hospitalized patients characterized by positive symptom with acute schizophrenia episode were recruited. At the time of enrollment, the demographic, symptomatic and laboratory data was collected. After the completion of the baseline assessment and examination, the patients were given aripiprazole. Clinical evaluation was performed at 1、2、4 and 8 weeks after treatment, including the therapeutic efficacy and adverse drug reactions ,and monitoring of laboratory data.
