Beta-methyl-digoxin concentrations in adipose, skeletal muscle and myocardial tissues, were studied in 8 patients undergoing by-pass surgery because of congenital heart disease. Correlation between doses/kg, plasmatic and tissue concentrations were analysed. We found statistically correlation between doses/kg and plasmatic concentrations; doses/kg and skeletal muscle concentrations (p less than 0.01); plasmatic and skeletal muscle concentrations (p less than 0.05). Concentrations was significantly greater in myocardial than adipose tissue before extracorporeal circulation (p less than 0.01); and significantly greater than adipose (p less than 0.01) and skeletal muscle (p less than 0.05) tissues after extracorporeal circulation. Extracorporeal circulation lessens adipose and skeletal muscle concentrations, but increases myocardial concentrations significantly (p less than 0.05). It is concluded, that the behaviour of beta-methyl-digoxin, in relation with tissue concentrations, is similar to digoxin.

UI	MeSH Term	Description	Entries

D008520	Medigoxin	A semisynthetic digitalis glycoside with the general properties of DIGOXIN but more rapid onset of action. Its cardiotonic action is prolonged by its demethylation to DIGOXIN in the liver. It has been used in the treatment of congestive heart failure (HEART FAILURE).

D009130	Muscle, Smooth	Unstriated and unstriped muscle, one of the muscles of the internal organs, blood vessels, hair follicles, etc. Contractile elements are elongated, usually spindle-shaped cells with centrally located nuclei. Smooth muscle fibers are bound together into sheets or bundles by reticular fibers and frequently elastic nets are also abundant.

D009206	Myocardium	The muscle tissue of the HEART. It is composed of striated, involuntary muscle cells (MYOCYTES, CARDIAC) connected to form the contractile pump to generate blood flow.

D002648	Child	A person 6 to 12 years of age. An individual 2 to 5 years old is CHILD, PRESCHOOL.	Children
D004077	Digoxin	A cardiotonic glycoside obtained mainly from Digitalis lanata; it consists of three sugars and the aglycone DIGOXIGENIN. Digoxin has positive inotropic and negative chronotropic activity. It is used to control ventricular rate in ATRIAL FIBRILLATION and in the management of congestive heart failure with atrial fibrillation. Its use in congestive heart failure and sinus rhythm is less certain. The margin between toxic and therapeutic doses is small.
