By employing the embryonic duck heart method to assay digitoxin quantitatively in extracts of human urine, it was found that, contrary to previous opinion, a large percentage of ingested or in-injected digitoxin is excreted via the kidney in a physiologically active state. Approximately 40 per cent of a digitalizing dose (1.2 mg.) is excreted over a period of 12 to 24 days. The average rate of renal excretion in theoretically digitalized normal young individuals was found to vary from 30 to 50 &mgr;g. of digitoxin per day, while those showing signs or symptoms of overdosage excreted significantly greater amounts of digitoxin.
