[Acute anicteric hepatitis and intrahepatic cholestasis caused by administration of prajmalium bitartrate (Neo-Gilurytmal)].

The authors draw attention to a serious drug response to the derivative of the alkaloid ajmaline prajmalium (Neo-Gilurytmal, Giulini-GFR) which causes impairment of liver functions of various grades as a result of intrahepatic cholestasis. They draw attention to the necessity of a careful pharmacological case-history, evaluation of the premorbid stage, in particular former liver disease or contemporary administration of drugs which burden liver function (hormonal contraceptives, non-steroid antirheumatic drugs). It is essential to follow-up liver functions by laboratory tests already at the onset of treatment with Neo-Gilurytmal.
