Documented Uses

• For the treatment of documented ventricular arrhythmias, such as sustained ventricular tachycardia, ventricular pre-excitation and cardiac dysrhythmias. It is a Class Ia antiarrhythmic drug.
• Disopyramide, a class 1A antiarrhythmic drug, received Food and Drug Administration approval on September 29, 1978, for established ventricular arrhythmias like sustained ventricular tachycardia that, in the physician's judgment, are life-threatening. As a Class Ia antiarrhythmic agent, disopyramide functions by blocking sodium channels in the cardiac cell membranes, which stabilizes cardiac electrical activity and can help restore a normal heart rhythm.
• Disopyramide is an oral antiarrhythmic agent that has been in wide use for several decades. Long term disopyramide therapy is associated with a low rate of serum enzyme elevations and is a rare cause of clinically apparent acute liver injury.
• Breast Feeding; Lactation; Milk, Human; Antiarrhythmics
• Take with or without food. The absorption is unaffected by food.
• Agents used for the treatment or prevention of cardiac arrhythmias. They may affect the polarization-repolarization phase of the action potential, its excitability or refractoriness, or impulse conduction or membrane responsiveness within cardiac fibers. Anti-arrhythmia agents are often classed into four main groups according to their mechanism of action: sodium channel blockade, beta-adrenergic blockade, repolarization prolongation, or calcium channel blockade.
