What is the trade name of Procainamide?

Procainamide is an antiarrhythmic medication that is primarily used to treat certain types of irregular heartbeats, known as arrhythmias. The trade name for Procainamide is Pronestyl, which reflects its historical use and the branding decision made by the manufacturer. Understanding the trade name is essential for healthcare professionals, as it aids in correctly identifying and prescribing medications for patients.

In the context of the other options, Sotalol, Lidocaine, and Amiodarone are all distinct antiarrhythmic drugs with their own profiles and uses. Sotalol is used for the treatment of ventricular and atrial arrhythmias, Lidocaine is primarily used for ventricular arrhythmias and as a local anesthetic, and Amiodarone is known for its effectiveness in treating a variety of severe heart rhythm problems. However, none of these medications is synonymous with Procainamide in terms of trade names. Hence, Pronestyl stands out as the correct answer.
