Actions biochimiques/physiologiques

Vernakalant is a multiple ion channel blocker that exerts in vivo anti-fibrillatory (anti-arrhythmic) efficacy (ED50 = 1.5 μmol/kg/min iv. against ischemia-induced arrhythmias in rats) via atrial-selective Kv1.5 blockage (hKv1.5/rKv4.2/rKv4.3 IC50 = 13/38/30 μM at 1Hz & -80 to 60 mV in 200 (Kv1.5) or 400 (Kv4) msec) as well as potential- and rate-dependent Nav1.5 blockade (inward Na current INa IC50 = 9 μM/20 Hz & -80 mV, 31 μM/1Hz & -60 mV, 107 μM/1Hz & -120 mV using HEK hNav1.5 cells).

Molecular dynamics simulations are employed to determine the inhibitory mechanisms of three drugs, 5-(4-phenoxybutoxy)psoralen (PAP-1), vernakalant, and flecainide, on the voltage-gated K+ channel Kv1.5, a target for the treatment of cardiac arrhythmia. At neutral pH, PAP-1 is neutral, whereas the

Evidence has emerged that small-conductance Ca2+-activated K+ (SK) channels constitute a new target for treatment of atrial fibrillation (AF). SK channels are predominantly expressed in the atria as compared with the ventricles. Various marketed antiarrhythmic drugs are limited by ventricular

The antiarrhythmic drug vernakalant exerts antiarrhythmic effects in atrial fibrillation. Recent experimental data suggest interactions with the late sodium current and antiarrhythmic effects in ventricular arrhythmias. We aimed at investigating whether treatment with vernakalant reduces polymorphic ventricular tachycardia (VT) in

Electrical remodeling plays a pivotal role in maintaining the reentry during atrial fibrillation. In this study, we assessed influence of electrical remodeling on pharmacological manipulation of the atrial refractoriness in rabbits. We used an atrial electrical remodeling model of the

Current guidelines recommend vernakalant for pharmacologic cardioversion of recent-onset atrial fibrillation. However, this drug is not established as chronic therapy. In total, 15 rabbit hearts were Langendorff-perfused. A burst pacing protocol-induced atrial fibrillation in 7 of 15 hearts at baseline
