The most probable mechanism of action for the positive inotropic effect of digitalis is inhibition of the membrane-bound NaK -ATPase pump directly which acts as the digitalis receptor. When this occurs Na increases in the cell the exchange of Na for Ca2 is augmented and calcium influx is increased. The FDA approved digoxin in 1975. What brand names are available for digoxin. Digoxin exerts hemodynamic electrophysiologic and neurohormonal effects on the cardiovascular system.

Some cardiac arrhythmias occur because of malfunctioning of this sodium-potassium pump resulting in calcium levels being too low on the inside of the cell to cause a contraction. This causes the intracellular or cytosolic Na concentration to remain higher which in turn disrupts the Na gradient needed to operate the Na Ca 2 exchange pump. Digoxin helps by interfering with the action of the sodium-potassium pump. This eMedTV page further explores how digoxins mechanism of action makes the heart more efficient. Digoxin has two principal mechanisms of action which are selectively employed depending on the indication.

When sodium within the cell increases another electrolyte mover. Diltiazem is a benzothiazepine derivative with antihypertensive antiarrhythmic properties. Inhibition of the sodiumpotassium ATPase pump in myocardial cells results in a transient increase of intracellular sodium which in turn promotes calcium influx via the sodium-calcium exchange pump leading to increased contractility. This leads to better blood circulation and reduced swelling of the hands and ankles in patients with heart problems.
