Digoxin is primarily used to treat which condition?

Digoxin is primarily used to treat heart rhythm problems, particularly atrial fibrillation and heart failure. It works by affecting the minerals in heart cells, ultimately improving how the heart functions. This medication helps to regulate the heart rate and improves its efficiency in pumping blood.

In patients with atrial fibrillation, digoxin can help control the irregular heartbeat, enhancing cardiac output and ensuring that the heart effectively delivers blood to the rest of the body. Its unique mechanism of action makes it a valuable option in managing certain heart conditions, distinguishing it from treatments used for the other listed conditions like seizures, migraines, or asthma. These other options rely on different classes of medications tailored specifically for their respective issues, which do not involve the same mechanisms as digoxin.
