Medicine Description lanoxin 0.05%
Lanoxin oral drops is a medication that contains digoxin, which primarily affects the sodium-potassium ATPase pump in cardiac myocytes. By inhibiting this enzyme, digoxin increases intracellular sodium levels, leading to increased calcium concentration as a result of altered sodium-calcium exchange. This mechanism enhances myocardial contractility, known as a positive inotropic effect, thereby improving the heart's ability to pump blood. Additionally, digoxin exerts a negative chronotropic effect by increasing vagal tone, which helps to slow down heart rate and control irregular rhythms, particularly in atrial fibrillation or flutter.
