Digoxin is a cardiac glycoside derived from the foxglove plant Digitalis lanata. It is primarily used in the treatment of various heart conditions, notably atrial fibrillation, atrial flutter, and sometimes heart failure that cannot be controlled by other medications. Digoxin is approved and widely used in clinical practice today.
Pharmacokinetics
Typical pharmacokinetic parameters for adult healthy volunteers after oral administration.
