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 a Class III antiarrhythmic; blocker of the delayed rectifier cardiac potassium channels; inhibits KV7.1 and KV11.1 potassium channels.
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

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

Implantable cardioverter defibrillators (ICDs) are now the mainstay of therapy in patients with sustained ventricular tachycardia (VT), ventricular fibrillation, resuscitated sudden cardiac death, or certain high-risk markers for these arrhythmic events. Although ICDs in such patients can be life-saving, they

We examined the effect of azimilide, a class III antiarrhythmic drug, on Na(+)/Ca(2+) exchange current (I(NCX)) in guinea-pig cardiac single ventricular cells. External application of azimilide suppressed bi-directional I(NCX) in a concentration-dependent manner. IC(50) values for outward and inward I(NCX)
