Digoxin has positive inotropic and negative chronotropic activity. It is used to control ventricular rate in atrial brillation and in the management of congestive heart failure with atrial brillation. Its use in congestive heart failure and sinus rhythm is less certain. The margin between toxic and therapeutic doses is small.

Structured Chronic Atrial Fibrillation (/indications/DBCOND0065022) Indications NYHA Class I or II heart failure (/indications/DBCOND0025082) NYHA Class III Heart Failure (/indications/DBCOND0048244) Pharmacodynamics Digoxin, a cardiac glycoside similar to digitoxin, is used to treat congestive heart failure and supraventricular arrhythmias due to reentry mechanisms, and to control ventricular rate in the treatment of chronic atrial brillation. Mechanism of Digoxin inhibits the Na-K-ATPase membrane pump, resulting in an increase in intracellular sodium. The sodium calcium exchanger (NCX)in turn tries to extrude the sodium action and in so doing, pumps in more calcium. Increased intracellular concentrations of calcium may promote activation of contractile proteins (e.g., actin, myosin). Digoxin also acts on the electrical activity of the heart, increasing the slope of phase 4 depolarization, shortening the action potential duration, and decreasing the maximal diastolic potential.
