Digoxin (Cardioxin) is a well-established cardiac glycoside used to treat heart failure and certain types of irregular heartbeats, such as atrial fibrillation. It helps the heart beat stronger and with a more regular rhythm, improving circulation and reducing symptoms like shortness of breath and swelling. Digoxin is available in tablet form, making it easy to incorporate into your daily medication routine. This medication has been used for decades and remains a cornerstone in cardiac care.
