title: Effect of intravenous injection of CDP-choline, S-adenosyl-methionine and citiolone in subjects with hyperlipemia.
abstract: The effect of some drugs (CDP-choline, S-adenosyl-methionine and acetyl-homocysteinethiolactone) stimulating a number of liver enzymatic activities was studied in hyperlipemic patients to explore the role of liver function in hyperlipidemia. Recently a close connection between liver impairment and hyperlipemia has been observed. Twenty-eight, 13 and 10 hyperlipemic subjects received i.v. doses respectively, of CDP-choline (300 mg), S-adenosyl-methionine (SAMe) (45 mg) and citiolone (300 mg) in 100 ml saline solution during a 30 minute period. Plasma lipid fractions were evaluated basally and at the end of the injection. CDP-choline caused a significant decrease in plasma total lipids (p less than 0.001), cholesterol (p less than 0.01) and triglycerides (p less than 0.01) as well as a slight increase in beta - LP (p less than 0.05). SAMe injection was followed by a significant fall in plasma total lipids (p less than 0.05), cholesterol (p less than 0.001) and beta - LP+pre-beta LP/alpha - LP ratio (p less than 0.05), while alpha -LP increased significantly (p less than 0.05). Citiolone caused only a decrease in plasma cholesterol values (p less than 0.001). The data suggest that the hypolipidemic effect of the three compounds is due to a common mode of action, i.e., the stimulation of hepatic phospholipid biosynthesis, though in a different way.
