What is Probucol?
Probucol is an anti-hyperlipidemic drug initially developed in the treatment of coronary artery disease.
However, clinical trials were stopped after it was found that it may lower HDL in patients with a previous history of heart disease.
Probucol was initially developed in the 1970s by a chemical company to maximize airplane tire longevity. Probucol is associated with QT interval prolongation.
Probucol lowers the level of cholesterol in the bloodstream by increasing the rate of LDL catabolism. Additionally, probucol may inhibit cholesterol synthesis and delay cholesterol absorption. Probucol is a powerful antioxidant which inhibits the oxidation of cholesterol in LDLs; this slows the formation of foam cells, which contribute to atherosclerotic plaques.
