Procainamide is a Class Ia antiarrhythmic drug used to treat and prevent various types of cardiac arrhythmias, including ventricular and supraventricular arrhythmias. It acts by blocking sodium channels in the heart. Procainamide is approved and still in clinical use, though less frequently than in the past due to alternative therapies and concerns regarding side effects.
Pharmacokinetics
Pharmacokinetic parameters reported for adult healthy volunteers after oral administration.
