1 Allosteric effects of erythromycin pretreatment on thioridazine block of hERG potassium channels. Thioridazine ETS transcription factor ERG Homo sapiens
2 Experiments were conducted to determine if concomitant exposure to two potent pore hERG blockers, thioridazine and terfenadine and a weak hERG blocker, erythromycin, would result in an additive, synergistic or inhibitory effect. Thioridazine ETS transcription factor ERG Homo sapiens
3 KEY RESULTS: Pre-exposure of cells to erythromycin resulted in an approximately 14-22-fold rightward shift in the hERG concentration-response curve for thioridazine and terfenadine respectively. Thioridazine ETS transcription factor ERG Homo sapiens
