Evaluation and mechanism study of cardiotoxicity caused by antipsychotics using human-induced pluripotent stem cell-derived cardiomyocytes
In this study, a comprehensive evaluation model for studying the cardiac toxicity of antipsychotic drugs was established by using iPSC-CMs. Six antipsychotic drugs, including aripiprazole, risperidone, quetiapine, haloperidol, clozapine, and olanzapine, all induced concentration-dependent QT prolongation in iPSC-CMs upon acute administration, and high concentrations of these drugs caused disorganized sarcomere arrangement in iPSC-CMs. Overall design: The experiments were divided into two groups, the control group and the Aripiprazole treatment group , n=3
