Metildigoxin
Metildigoxin ( INN, or medigoxin BAN, or methyldigoxin) is a cardiac glycoside, a type of drug that can be used in the treatment of congestive heart failure and cardiac arrhythmia (irregular heartbeat). The substance is closely related to digoxin; it differs from the latter only by an O- methyl group on the terminal monosaccharide.
