procainamide profile

Procainamide is a class I antiarrhythmic drug used to treat atrial fibrillation, ventricular tachycardia, and other cardiac arrhythmias. It is synthesized by reacting procaine with p-aminobenzoic acid. Procainamide works by blocking sodium channels in the heart, slowing the conduction of electrical impulses through the heart and reducing the excitability of the heart muscle. It is important because it is an effective treatment for a variety of cardiac arrhythmias. Procainamide is studied to understand its mechanisms of action and its effects on the heart, as well as to develop new and more effective antiarrhythmic drugs.'
