disopyramide

Last reviewed 01/2018

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.
