[Proceedings: Clinical value of serum digoxin and digitoxin determination in renal insufficiency]

Abstract

Plasma digoxin and digitoxin determination has proven to have an important bearing, particularly in patients with renal failure. It permits early detection of digitalis intoxication in the absence of marked clinical and ECG evidence, and adjustment of dosage accordingly. Also, in patent intoxication it makes it possible to select the right moment for resumption of therapy. To illustrate the importance of the method some cases are cited involving plasma digoxin and digitoxin determination.
