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 effects of chronic oral azimilide therapy on the ventricular defibrillation threshold (DFT) during ischemia are unknown. The effects of azimilide on defibrillation efficacy under ischemic condition were investigated in a closed-chest animal model. Azimilide (20 mg/kg/d) was administered orally

Hyperkalemia is a potentially life-threatening disorder frequently occurring in hospitalized patients. The ischemic myocardium releases potassium into the extracellular space which can cause regional hyperkalemia. These changes may modify the effects of anti-arrhythmic drugs acting on the rapid component of
