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.

Aprindine, an arrhythmia inhibitor, stabilizes the cell membranes of heart muscle cells to prevent abnormal electrical impulses and irregular heartbeats. In hematological toxicity studies, aprindine demonstrated potential inhibitory effects on the replicative capacity of mouse and human blood cells at specific concentrations [1].
