Introduction: Citrus juice has been shown to cause QT prolongation in electrocardiograms of healthy volunteers, and naringenin, a major flavonoid found in citrus juice, has been identified as the potent inhibitor of human ether-a-go-go-related gene (HERG) channels as the cause of QT prolongation. Inhibition of HERG channels and prolongation of QT interval by antipsychotic drugs such as haloperidol, chlorpromazine, and clozapine have also been shown. However, naringenin's effect on HERG channel function in conjunction with antipsychotic medications has not been investigated.
Methods: In the present study, we evaluated the effect of combining naringenin with antipsychotics on the function of HERG channels expressed in Xenopus oocytes.
Results: When 30 µ
Conclusion: The results suggest that there is an additive interaction between antipsychotics and naringenin. Due to the potential for repolarization heterogeneity and a decrease in repolarization reserve, this additive HERG inhibition may increase the risk of arrhythmias.
