[Liver failure caused by flutamide].
Flutamide is a non-steroidal anti-androgen used in the treatment of prostate cancer, usually in combination with LHRH-analogs. Incidence of hepatotoxicity associated to Flutamide in the literature is very low and does not exceed 0.18%. Between February 1989 and December 1994, the FDA was reported 20 cases of patients who had died and 26 who had been hospitalized due to hepatotoxicity secondary to Flutamide. We contribute two cases of patients diagnosed with prostate adenocarcinoma following treatment with flutamide and LHRH-analogs who presented liver failure; one with signs and symptoms of acute hepatitis that recovered after discontinuation of the drug, and a second one who developed micronodular cirrhosis and later died of icteroascitic decompensation and hepatorenal syndrome. Including a review of the literature, the paper comments on the likely biological mechanisms for liver toxicity caused by Flutamide. The authors conclude that clinical and laboratory monitoring of patients who either will receive or are receiving treatment with Flutamide is necessary, and withdrawal of drug imperative as soon as certain symptoms of hepatic dysfunction become apparent.
