Core Tip
Core Tip: This study aims to explore drug-drug interactions and initial dosage optimization of aripiprazole in patients with bipolar disorder (BD). Aripiprazole clearance rate increases 66.7% in patients with BD taking sodium valproate sustained-release tablet. The present study explores the drug-drug interactions and initial dosage optimization of aripiprazole in patients with BD based on virtual clinical trial for the first time. When sodium valproate sustained-release tablet is used in combination, the clearance of aripiprazole in patients with BD is accelerated, and the dosage of aripiprazole in patients with BD need to be increased.
