Overview[edit | edit source]

Digoxin[edit | edit source]

Indications for Digoxin[edit | edit source]

Background[edit | edit source]

  • Inhibits Na,K+-ATPase resulting in an increase in intracellular Na+, extracellular Ca2+ exchange increasing the velocity and extent of sarcomere shortening.
  • ACC/AHA recommend digoxin for symptomatic patients with left ventricular systolic dysfunction.
  • Commonly used in patients with heart failure and atrial fibrillation to reduce the ventricular response rate.
  • Mortality has not been shown to be improved with use of digoxin[1], but the use of digoxin has been associated with a reduction in hospitalization in the RALES study.
  • There is no need to load a CHF patient with digoxin. For the majority of patients with normal renal function, a daily dose of 0.25 mg of digoxin is usually adequate. In the older patient or in those patients with renal impairment, a dose of 0.125 mg per day may be adequate.
  • Drugs that increase the concentration of digoxin include antibiotics and anticholinergic agents as well as amiodarone, quinidine and verapamil.
  • In the RALES study, a level of < 1 ng/ml was associated with efficacy. Levels above 1 ng/ml were not associated with greater efficacy and were associated with higher mortality.

Digitalis in Patients Presenting With Heart Failure (DO NOT EDIT) [2][3][edit | edit source]

Class IIa
"1. Digitalis can be beneficial in patients with current or prior symptoms of heart failure and reduced left ventricular ejection fraction (LVEF) to decrease hospitalizations for heart failure. [1][4][5][6][7][8][9][10] (Level of Evidence: B) "
