1 Effects of the histamine H(1) receptor antagonist hydroxyzine on hERG K(+) channels and cardiac action potential duration. Hydroxyzine ETS transcription factor ERG Homo sapiens
2 AIM: To investigate the effects of hydroxyzine on human ether-a-go-go-related gene (hERG) channels to determine the electrolphysiological basis for its proarrhythmic effects. Hydroxyzine ETS transcription factor ERG Homo sapiens
3 Hydroxyzine (0.03-3 mumol/L) blocked both the steady-state and tail hERG currents. Hydroxyzine ETS transcription factor ERG Homo sapiens
4 CONCLUSION: The results suggest that hydroxyzine could block hERG channels and prolong APD. Hydroxyzine ETS transcription factor ERG Homo sapiens
