Disopyramide (INN, trade names Norpace and Rythmodan) is an antiarrhythmic medication. It is a Class Ia antiarrhythmic (sodium channel blocker) used in the treatment of ventricular tachycardias. It has no effect on alpha or beta adrenergic receptors. It resembles quinidine but it has a marked anti-muscarinic effect on the heart, for this reason, it is not considered as a drug of 1st choice. It is also used in ventricular arrhythmia and supraventricular arrhythmia that might follow myocardial infarctions.
