Aprindine HCl is a Class 1b antiarrhythmic agent used to manage ventricular and supraventricular arrhythmias. In one study, it delayed atrial fibrillation more than digoxin did. It has shown effectiveness when given orally.
Atecegatran Metoxil (Atecegatran Fexenetil ,AZD0837) is an oral direct thrombin inhibitor,which currently in clinical development for the prevention of stroke and systemic embolic events in patients with atrial fibrillation. AZD0837 is a selective and re
Budiodarone(ATI-2042)is a chemical analog of an antiarrhythmic drug and amiodarone. Budedalone is promising as an antiarrhythmic agent for the prevention of atrial fibrillation.
KCa2 (small conductance Ca2+-activated potassium) channel negative allosteric modulator (IC50 = 1.1 μM). Increases the EC50 of Ca2+ on KCa2.3 channels by ~3-fold. Prolongs atrial effective refractory period (AERP) in rats. Reduces atrial fibrillation (AF) duration and prolongs atrial refractoriness without affecting ventricular refractory period in an animal AF model.
