Digoxin is a glycoside extracted from the foxglove plant Digitalis lanata. Its primary mechanism of action is to inhibit alpha subunits of the Na+/K+ ATPase pump located in the plasma membrane of human myocytes. This inhibition leads to an increase in intracellular calcium concentration and an increase in myocardial contraction. Digoxin also results in a decrease of electrical impulse conduction through the AV node. Digoxin is widely used in the treatment of various heart conditions, namely atrial fibrillation, atrial flutter and atrial tachycardia.
