WebBoth drugs blocked hERG currents in a concentration-dependent manner with an IC50 value of 2.6 μM for escitalopram and an IC50 value of 3.2 μM for citalopram. The blocking of hERG by escitalopram was voltage-dependent, with a steep increase across the voltage range of channel activation. WebMar 1, 1996 · This apparent discrepancy may be due to differences in channel characteristics (HERG versus guinea pig and mouse I Kr ), tissue (oocytes versus myocytes), or specific drugs.
