Digoxin undergoes hepatic metabolism independent of CYP-450 system and is renally excreted. Half-life is 1.5-2 days in healthy adults, but can be 4-6 days in patients in renal failure. Digoxin has a narrow therapeutic window, typically 0.5-1.0 ng/mL, with toxicity range beginning at concentrations greater than 2.0 ng/mL.Heart Failure. As per ACCF/AHA guidelines, a loading dose to initiate digoxin therapy in patients with heart failure is not necessary. 0.125-0.25 mg PO/IV qDay; higher doses including 0.375-0.5 mg/day rarely needed. Use lower end of dosing (0.125 mg/day) in patients with impaired renal function or low lean body mass.Digoxin increases intracellular calcium in myocardial cells indirectly, by inhibiting the sodium-potassium pump in the cell membrane. Increased intracellular calcium increases cardiac contractility, but also the risk of tachyarrhythmias. 8 Inhibition of this pump causes the hyperkalaemia commonly seen in toxicity.In many cases, digoxin is used in the management of congestive heart failure.
