  digoxin \di*gox"in\, n. (Chem.)
     a steroid glycoside, one of the cardiotonic chemical
     substances which is extracted from the foxglove. It is a
     white, crystalline substance ({C41H64O14}), and is a
     3-substituted triglucoside of a steroid, related structurally
     to digitalin and digitoxin. It is used as a cardiotonic for


     treatment of certain heart conditions, such as congestive
     heart failure. Chemically it is
  
     (3[beta],5[beta],12[beta])-3-[(O-2,6-Dideoxy-[beta]-D-ribo-hexopyranosyl-(1->4)-O-2,6-dideoxy-[beta]-D-ribo-hexopyranosyl-(1->4)-2
  ,  6-dideoxy-[beta]-D-ribo-hexopyranosyl)oxy]-12,14-dihydroxy-card-20(22)-enolide.
     The related compounds {digitalin} and {digoxin} are also
     extracted from the foxglove ({Digitalis lanata} and
     {Digitalis purpurea}). The class of steroid glycosides having
     cardiotonic properties are refered to as the cardiac
     glycosides. --MI11
