Digoxin is one of the cardiac (or digitalis) glycosides, a closely related group of drugs having in common specific effects on the myocardium. These drugs are found in a number of plants. Digoxin is extracted from the leaves of Digitalis lanata . The term “digitalis” is used to designate the whole group of glycosides. The glycosides are composed of two portions: a sugar and a cardenolide (hence “glycosides”). Digoxin has the chemical name: 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, and the following structural formula: Digoxin exists as odorless white crystals that melt with decomposition above 230°C. The drug is practically insoluble in water and in ether; slightly soluble in diluted (50%) alcohol and in chloroform; and freely soluble in pyridine. Digoxin Injection is a sterile solution for slow intravenous or deep intramuscular injection. Each mL contains digoxin 250 mcg (0.25 mg), alcohol 0.1 mL, propylene glycol 0.4 mL, dibasic sodium phosphate, anhydrous 3 mg and citric acid, anhydrous 0.8 mg in Water for Injection. pH 6.7-7.3; citric acid and/or sodium phosphate added, if necessary, for pH adjustment. Dilution is not required. Formula1.jpg
