Q: Digoxin acts by-
  • A. Inhibiting H+/K+ ATPase
  • B. Inhibiting Na+/K+ ATPase
  • C. Stimulating Na+/K+ ATPase
  • D. Stimulating H+/K+ ATPase
Correct Answer: Option B - Digoxin is a medication used to manage and treat heart failure and certain arrhythmias. It is the cardiac glycoside class of drugs. Digoxin compounds are potent inhibitors of cellular Na+/k+ – ATPase. This ion transport system moves sodium ions out of the cell and brings potassium ions into the cell. The Na+/K+ – ATPase also play an active role in membrane potential generation .
