Acetyldigitoxin is only found in individuals that have used or taken this drug. It is a cardioactive derivative of lanatoside A or of digitoxin used for fast digitalization in congestive heart failure.Acetyldigitoxin binds to a site on the extracellular aspect of the α-subunit of the Na⁺/K⁺ ATPase pump in the membranes of heart cells (myocytes). This causes an increase in the level of sodium ions in the myocytes, which then leads to a rise in the level of calcium ions. The proposed mechanism is the following: inhibition of the Na⁺/K⁺ pump leads to increased Na⁺ levels, which in turn slows down the extrusion of Ca²⁺ via the Na⁺/Ca²⁺ exchange pump. Increased amounts of Ca²⁺ are then stored in the sarcoplasmic reticulum and released by each action potential, which is unchanged by acetyldigitoxin. This is a different mechanism from that of catecholamines. Acetyldigitoxin also increases vagal activity via its central action on the central nervous system, thus decreasing the conduction of electrical impulses through the AV node. This is important for its clinical use in different arrhythmias. 3-O-acetyldigitoxin is a cardenolide glycoside compound consisting of digitoxin having an acetyl substituent at the 3-position on the D-ribo-hexopyranosyl residue at the non-reducing end. It has a role as an anti-arrhythmia drug, a cardiotonic drug and an enzyme inhibitor. It is functionally related to a digitoxin. Cardioactive derivative of lanatoside A or of digitoxin used for fast digitalization in congestive heart failure. Acetyldigitoxin is a natural product found in Digitalis grandiflora and Digitalis lanata with data available. Cardioactive derivatives of lanatoside A or of DIGITOXIN. They are used for fast digitalization in congestive heart failure. See also: Digitoxin (has active moiety) ... View More ...
