How does Quinidine work in the body?
Quinidine works by blocking certain electrical signals in the heart that can cause an irregular heartbeat. It stabilizes the heart's rhythm by affecting the sodium and potassium channels in the heart cells. This action helps to restore a normal heart rhythm and prevent the recurrence of arrhythmias. By doing so, Quinidine reduces the risk of complications associated with irregular heartbeats, such as stroke or heart failure.
