It inhibits KV7.1 and KV11.1 potassium channels. Azimili
2、des block of K+ currents is relatively selective for IKr over IKs: It potently blocks the rapidly activating component of the delayed rectifier, IKr (IC50 0.4 mM), and inhibits IKs (IC3 mM) with nearly 10-fold less potency. At 10 mM, it does not block the inward rectifier K+ current. It blocks (10 m
