Digoxin's primary mechanism of action involves inhibition of the sodium potassium adenosine triphosphatase (Na+/K+ ATPase), mainly in the myocardium. This inhibition causes an increase in intracellular sodium levels, resulting in decreased activity of the sodium-calcium exchanger, which normally imports three extracellular sodium ions into the cell and transports one intracell… WebMECHANISM OF ACTION. digibind has a much higher affinity (high affinity (10 9 –10 10 L/mol) for digoxin than the Na+/K+ ATPase digoxin receptor site; binds to digoxin in the extracellular spaces preventing digoxin binding to the Na+/K+ ATPase; creates a concentration gradient that extracts digoxin from the intracellular space
