Application

Azimilide dihydrochloride may be used in the electrophysiology experiments with human ether-a-go-go-related gene 1a (HERG1a) subunit.

Biochem/physiol Actions

Azimilide is an inhibitor of human ether-a-go-go-related gene (HERG) channel. It displays a decrease in inhibitory effect in acidic pH conditions.
Azimilide is an investigational class III anti-arrhythmic drug that blocks fast and slow components of the delayed rectifier cardiac potassium channels. It inhibits KV7.1 and KV11.1 potassium channels. Azimilide′s 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 (IC50 3 mM) with nearly 10-fold less potency. At 10 mM, it does not block the inward rectifier K+ current. It blocks (10 mM) the L-type Ca2+ current (ICa) in a use-dependent manner.

The goal of this study was to determine whether azimilide, as compared with placebo, will reduce the number of emergency department (ED) visits and hospitalizations caused by arrhythmias or cardiac events in patients with an implantable cardioverter-defibrillator (ICD). Patients with

Acidosis is one of the important deleterious factors during myocardial ischaemia and reperfusion. The ether-a-go-go-related gene, HERG, is a primary target for blockade by many drugs including dofetilide, quinidine and azimilide. While most drugs lose their efficacy against arrhythmias associated

Antiarrhythmic drug therapy, broadly defined, is the mainstay of treatment and prevention of ventricular tachycardia (VT)/ventricular fibrillation (VF), which can lead to sudden death. This article evaluates the evidence for and appropriate use of class I antiarrhythmic drugs, class III

Nifekalant and azimilide, Class III antiarrhythmic agents, block the human ether-à-go-go-related gene K(+) (hERG) channel. However, when a depolarizing membrane potential is applied, they also increase the current at low potentials by shifting its activation curve towards hyperpolarizing voltages. This
