Aprindine HCl is a Class 1b antiarrhythmic agent used to manage ventricular and supraventricular arrhythmias. In one study, it delayed atrialfibrillation more than digoxin did. It has shown effectiveness when given orally.
Flecainide acetate is a class Ic antiarrhythmic agent, it is used to treat a variety of cardiac arrhythmias including paroxysmal atrialfibrillation, paroxysmal supraventricular tachycardia, and ventricular tachycardia. It works by regulating the flow of
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 atrialfibrillation. 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 atrialfibrillation.
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 atrialfibrillation (AF) duration and prolongs atrial refractoriness without affecting ventricular refractory period in an animal AF model.

AP14145 hydrochloride is a potent negative allosteric modulator of K Ca 2 (SK) channels, specifically targeting K Ca 2.2 (SK2) and K Ca 2.3 (SK3) channels with an IC 50 of 1.1 μM. Inhibition of AP14145 hydrochloride is highly influenced by S508 and A533 amino acids present in the channel. This compound effectively extends the atrial effective refractory period (AERP) in rats and exhibits antiarrhythmic properties in a Vernakalant-resistant porcine model of atrialfibrillation (AF).
