Background:

Digoxin-d3is intended for use as an internal standard for the quantification of digoxin by GC- or LC-MS. Digoxin is a cardiac glycoside and metabolite of digitoxin that binds to and inhibits the Na+/K+-ATPase in cardiac tissues in an ATP- and Mg2+-dependent manner.1This inhibition results in loss of the transmembrane Na+gradient, which decreases activity of the Na+/Ca2+exchanger, increasing intracellular Ca2+levels, inotropy, and cardiac force.2It increases activity of mitochondrial ATPase and actomyosin ATPase in rat hearts, which is directly correlated with increased myofibrillar contractile strength.3In vivo, digoxin also decreases right atrial pressure and increases cardiac output in a canine model of congestive heart failure produced by pulmonary artery constriction.4Formulations containing digoxin have been used to treat atrial fibrillation.5
