Propafenone-induced liver injury: report of a case and review of the literature

Abstract

A case of an acute cholestatic syndrome associated with use of the antiarrhythmic drug propafenone is reported here. The close time relationship between the administration of the drug and the acute onset of the liver damage, the histological findings, and the reappearance of biochemical signs of liver dysfunction upon rechallenge with the same medication strongly suggest that propafenone was involved in the pathogenesis of this syndrome. Although rare, hepatotoxicity from this widely used antiarrhythmic medication should be kept in mind in the differential diagnosis of sudden cholestatic syndrome of obscure origin.
