Lanoxin is simply a brand name for digoxin, a medication used to treat heart failure and irregular heartbeats like atrial fibrillation. It works by strengthening heart contractions and controlling the heart rate. Lanoxin helps the heart pump blood more effectively throughout the body. Essentially, it's the same drug as digoxin, just marketed under a specific brand name. Think of it like the difference between Advil and ibuprofen; both contain the same active ingredient.
