How Does Dofetilide Work?

Dofetilide is a medication used to treat irregular heartbeats, specifically atrial fibrillation and atrial flutter. It helps your heart maintain a normal rhythm by affecting the electrical signals in the heart.

Mechanism of Action (Simple Terms):

Dofetilide works by blocking specific potassium channels in heart cells. This action slows down the electrical signals that cause irregular heartbeats, allowing the heart to beat more regularly.

Additional Details:

• It primarily affects the heart's electrical system, helping restore and maintain a steady rhythm.
• Dofetilide does not directly interact with hormones or the nervous system but targets heart muscle cells.
• By prolonging the electrical recovery phase of heart cells, it reduces abnormal rapid heart rhythms.

This targeted action makes dofetilide effective in managing certain types of arrhythmias safely when used as prescribed.
