Flecainide Acetate

Where is Flecainide Acetate used?

Flecainide Acetate is a type of medicine called anti-arrhythmic used in conditions such as:

  • Persistent ventricular tachycardia
  • Paroxysmal supraventricular tachycardia

These are types of serious irregular heartbeats. This medicine blocks certain electrical signals on the heart that can cause an irregular heartbeat. Giving treatment to these types of conditions can lessen the risk of blood clots which also lowers your risk of having a stroke or heart attack. Flecainide Acetate is an FDA-approved prescription for oral use.

How does Flecainide Acetate work?

Flecainide Acetate decreases the sensitivity of the heart muscle cells to electrical impulses. This normalizes the electrical conduction in the heart muscle which helps to repair conflicts in the heart rhythm.

The pumping action of the heart is controlled by the electrical signals and causes the left and right atria and ventricles to contract and produce the heartbeat. If the electrical activity in the heart is disturbed for any reason, irregular heartbeats of various types can result. These can extremely weaken the pumping action of the heart and might cause unproductive blood circulation around the body.
