Lanatoside C (or isolanid) is a cardiac glycoside, a type of drug that can be used in the treatment of congestive heart failure and cardiac arrhythmia (irregular heartbeat). Lanatoside C can be used orally^[1] or by the intravenous route.^[2] It is marketed in a number of countries and is also available in generic form.^[3] Its main indications are rapid response atrial fibrilation and paroxysmal supraventricular tachycardia, two common types of arrhythmia.

It is found in Digitalis lanata.^[4]

Chemistry

The substance is composed of four monosaccharides (glucose, 3-acetyldigitoxose and two digitoxoses) and an aglycon named digoxigenin.^[5]
