α-Acetyldigoxin is a cardiac glycoside found in plants of the genus Digitalis, including Digitalis lanata.^[1] It is an acetyl derivative of digoxin and an isomer of β-acetyldigoxin.

α-Acetyldigoxin increases the contractility of the heart by its positive inotropic effect on cardiac muscle.^{[citation needed]} The effects of α-acetyldigoxin begin 3–4 hours after administration, and maximize after 6–8 hours.^{[citation needed]} It is prescribed for congestive chronic cardiac failure class II, III and IV.^{[citation needed]}
