Procainamide

Also Known As: Procainamide, Procanbid

Procainamide INN is a pharmaceutical antiarrhythmic agent used for the medical treatment of cardiac arrhythmias, classified by the Vaughan Williams classification system as class Ia.

This drug is used for both supraventricular and ventricular arrhythmias. For example, it can be used to convert new-onset atrial fibrillation, though it is suboptimal for this purpose. It can also be used to treat Wolf-Parkinson-White syndrome by prolonging the refractory period of the accessory pathway. Typically use is secondary to lidocaine in patients who are allergic to lidocaine or dysrhythmias that are refractory to lidocaine.
