Aim: The purpose of this study was to evaluate the clinical utility of pharmacogenetic (PGx) testing in the treatment of bipolar disorder in the Chinese population. Patients & methods: Compare efficacy and side effects, measured by the Clinical Global Impression Efficacy Index scale (CGI-EI), of PGx-guided treatment (n = 100) to that of the traditional treatment (n = 100). Results: Compared with the traditional treatment, PGx-guided treatment reduced the number of medications used for patients, also achieving better efficacy at 4, 8 and 12 weeks. In the analysis of side effects, the PGx-guided group significantly reduced the side effects. Conclusion: Our study suggests that PGx testing results-guided treatment is superior to the traditional treatment of bipolar disorder in the Chinese population.
