Digoxin is extracted from the leaves of the common foxglove, Digitalis lanata . Like each of the other cardiac glycosides, digoxin consists of a polycyclic core and a sugar side chain. Digoxin’s chemical name is 3β-[O-2,6-dideoxy-β-D-ribo-hexopyranosyl-(1→4)-O-2,6-dideoxy-β-D-ribo-hexopyranosyl-(1→4)-2,6-dideoxy-β-D-ribo-hexopyranosyl)oxy]-12β,14-dihydroxy-5β-card-20(22)-enolide; its structural formula is: Its molecular formula is C 41 H 64 O 14 , and its molecular weight is 780.94. Digoxin is practically insoluble in water and in ether, slightly soluble in 50% ethanol and in chloroform, and freely soluble in pyridine. Digoxin, USP is a white or almost white powder, or colorless crystals. Digoxin Oral Solution, USP is formulated for oral administration. Each mL contains 50 mcg digoxin. The solution contains the following inactive ingredients: alcohol 10% (by volume at 60°F), glycerin, methylparaben 0.1%, propylparaben 0.02%, purified water, sodium citrate dihydrate, and sorbitol solution. image description
