The main purpose of this cohort study is to evaluate the efficiency and safety of Dayingpian to provide evidence-based medical evidence for the subsequent drug development.
Dayingpian is a kind of formula in traditional Chinese medicine with the effect of promoting blood circulation and reducing blood stasis. It has been prescribed as an add-on in the treatment of mental disorders such as bipolar disorder. However, there is not yet much high-quality evidence of the clinical effectiveness of Dayingpian treatment. In this study, we conduct a prospective, real-world longitudinal cohort study at Shanghai Mental Health Center in China to investigate the efficacy and safety of Dayingpian for bipolar disorder patients. The observation period is 12 weeks and all participants are evaluated every 4 weeks.
