Mechanisms of Hepatic Cholestatic Drug Injury.

Drug-induced cholestasis represents a form of drug-induced liver disease that can lead to severe impairment of liver function.

This review focuses on the various pathological mechanisms by which drugs express their hepatotoxic effects, as well as consequences of increased bile acid and toxin accumulation in the hepatocytes.
