The Rate of Disappearance of Lanatoside C. and Digitoxin from the Blood of Rats

Abstract
By means of the embryonic duck heart preparation, both lanatoside C. and digitoxin could be detected and quantitatively measured in the sera of rats after parenteral administration of both drugs. A study of the behavior of the two glycosides in blood indicated that a striking difference existed in the respective rates of disappearance of both drugs from the bloodstream.
