Disopyramide is:

  • a class IA antiarrhythmic drug and as such is effective against atrial and ventricular arrhythmias

  • is often used to control ventricular arrhythmias post myocardial infarction

  • moderately arrhythmogenic

  • is negatively inotropic and so must be used with caution in patients with heart failure

Disopyramide may have anti-cholinergic side-effects such as dry mouth, blurred vision and urinary retention.
