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
In a therapeutic study, 120 inpatients suffering from congestive heart failure were treated with a daily maintenance dose of 0.3 mg pengitoxin (penta-acetyl-gitoxin) over several weeks or months. The plasma level and the glycoside concentration in urine were measured by radioimmunoassay. The
The exogenous digitalis glycosides, ouabain and digoxin, have been widely used in humans to treat congestive heart failure and cardiac arrhythmias. Several reports have also pointed to the existence of endogenous ouabain- and digoxin-like compounds, but their precise roles in mammalian physiology
The Na,K-ATPase is specifically inhibited by cardiotonic steroids (CTSs) like digoxin and is of significant therapeutic value in the treatment of congestive heart failure and arrhythmia. Recently, new interest has arisen in developing Na,K-ATPase inhibitors as anticancer agents. In the present
