Description

Biochem/physiol Actions

Anti-arrhythmic that exerts anti-fibrillatory efficacy via potential- & rate-dependent Nav1.5 (SCN5A) as well as atrial-selective Kv1.5 (KCNA5) blockade in vivo.

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).
