Clinical Trial Summary

Study objectives: 1. Describe the characteristics of discharged patients with schizophrenia achieving functional remission after drug discontinuation. 2. Establish a prediction model of patients with schizophrenia having good prognosis after drug discontinuation.

Description:

There are 2 clinically important and urgent questions to be explored in this study: 1. Who is more likely to benefit from guided drug reduction or discontinuation? How to design an individualized treatment plan which can balance the risk of relapse and side-effects from antipsychotics? 2. What are the predictors of functional remission in patients with schizophrenia after drug discontinuation? This will be the first related study to be conducted in China.
