Antiarrhythmic Drugs and Their Effects on Cardiac KCa2 Chann
2026-04-22
This study systematically evaluates whether clinically recommended antiarrhythmic drugs (AADs) for atrial fibrillation (AF) inhibit small conductance calcium-activated potassium (KCa2.X/SK) channels, a promising atrial-selective target. The authors demonstrate that, unlike most AADs, only dofetilide and propafenone inhibit hKCa2.2 and hKCa2.3 channels, but at concentrations far above therapeutic plasma levels, suggesting limited clinical relevance.
