Contrasting effect on cardiac output of digoxin and gitoxin in humans during congestive heart failure. 1981

J Col, and W Wijns, and L Brasseur, and M Lesne

Recent studies have demonstrated that the biovailability of gitoxin could be increased to 100%. Favorable pharmacokinetic parameters for this glycoside have also been found in humans. The present paper deals with the comparative hemodynamic effect of digoxin and gitoxin on nine patients suffering from heart failure. The study was conducted in a coronary care unit with continuous hemodynamic monitoring. After intravenous administration of 1 mg digoxin or gitoxin, only gitoxin was observed to have an inotropic effect leading to significant improvement of the low cardiac output in these patients.

D008297 Male Males
D002301 Cardiac Glycosides Cyclopentanophenanthrenes with a 5- or 6-membered lactone ring attached at the 17-position and SUGARS attached at the 3-position. Plants they come from have long been used in congestive heart failure. They increase the force of cardiac contraction without significantly affecting other parameters, but are very toxic at larger doses. Their mechanism of action usually involves inhibition of the NA(+)-K(+)-EXCHANGING ATPASE and they are often used in cell biological studies for that purpose.

D002302 Cardiac Output The volume of BLOOD passing through the HEART per unit of time. It is usually expressed as liters (volume) per minute so as not to be confused with STROKE VOLUME (volume per beat). Cardiac Outputs,Output, Cardiac,Outputs, Cardiac
D004077 Digoxin A cardiotonic glycoside obtained mainly from Digitalis lanata; it consists of three sugars and the aglycone DIGOXIGENIN. Digoxin has positive inotropic and negative chronotropic activity. It is used to control ventricular rate in ATRIAL FIBRILLATION and in the management of congestive heart failure with atrial fibrillation. Its use in congestive heart failure and sinus rhythm is less certain. The margin between toxic and therapeutic doses is small.

D006333 Heart Failure A heterogeneous condition in which the heart is unable to pump out sufficient blood to meet the metabolic need of the body. Heart failure can be caused by structural defects, functional abnormalities (VENTRICULAR DYSFUNCTION), or a sudden overload beyond its capacity. Chronic heart failure is more common than acute heart failure which results from sudden insult to cardiac function, such as MYOCARDIAL INFARCTION.
