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,[citation needed] two common types of arrhythmia.
