Flecainide
Flecainide is an anti-arrhythmic medicine used to treat and prevent serious irregular heart rhythms, particularly in conditions like atrial fibrillation and ventricular arrhythmias. It works by stabilizing the heart's electrical activity, helping the heart beat more regularly. Flecainide is usually prescribed when other treatments have not been effective. It is available in tablet form and should be taken strictly under medical supervision due to potential side effects and interactions with other medications.
Uses of Flecainide
- Treatment of atrial fibrillation (irregular heartbeat)
- Prevention of paroxysmal supraventricular tachycardia (PSVT)
- Management of ventricular tachycardia (fast heart rate from the lower chambers)
- Used in certain genetic heart rhythm conditions like Brugada syndrome (under specialist care)
How Flecainide Works
Flecainide works by blocking sodium channels in the heart, which helps slow down electrical signals. This stabilizes the heart rhythm and prevents abnormal electrical activity that leads to arrhythmias. It allows the heart to pump blood more efficiently by maintaining a regular heartbeat.
Benefits of Flecainide
- Helps maintain a normal and steady heartbeat
- Reduces the risk of stroke related to atrial fibrillation
- Improves quality of life by reducing palpitations and fatigue
- Effective in preventing recurrence of heart rhythm disorders
