Digoxin-d3 is intended for use as an internal standard for the quantification of digoxin (Item No. 22266) by GC- or LC-MS. Digoxin is a cardiac glycoside and metabolite of digitoxin (Item No. 27825) that binds to and inhibits the Na+/K+-ATPase in cardiac tissues in an ATP- and Mg2+-dependent manner.{38192} This 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.{38193} It increases activity of mitochondrial ATPase and actomyosin ATPase in rat hearts, which is directly correlated with increased myofibrillar contractile strength.{38194} In vivo, digoxin also decreases right atrial pressure and increases cardiac output in a canine model of congestive heart failure produced by pulmonary artery constriction.{38195} Formulations containing digoxin have been used to treat atrial fibrillation.{38196}
