Drug-induced hepatic injury is a potential complication of virtually all drugs because the liver is central to the metabolic disposition of almost all drugs, although precise mechanisms often are unknown. We report a case of severe acute mixed hepatitis (cholestatic and hepatocellular), probably induced by alfuzosin. This event has not been reported previously (MEDLINE 1990, March 1999). Viral causes, autoimmune hepatitis and biliary tree obstruction were excluded. After discontinuation of the drug, liver function test results returned to normal.
