Probucol is an anti-hyperlipidemic drug[1] 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.

Mechanism[edit]

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.[2] 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.

It is believed to act at ABCA1.[3]

It also lowers levels of HDL.[4]
