Flecard 50mg contains Flecainide Acetate, a Class 1C antiarrhythmic agent used to treat and prevent serious heart rhythm disorders (arrhythmias), such as atrial fibrillation, supraventricular tachycardia (SVT), and ventricular arrhythmias. It works by slowing electrical signals in the heart to restore normal rhythm and maintain a steady heartbeat.
This medication is typically prescribed when other antiarrhythmic drugs are not effective or suitable.
