Abstract
Treatment of chronic hepatitis C infection withinterferon has been disappointing, with less than onethird of patients achieving a sustained response andmost experiencing significant side effects. For these reasons, an open-labeled prospectivepilot study was conducted to test the safety andefficacy of the antiviral drug, amantadine, in patientswith chronic hepatitis C infection who had previously failed therapy withinterferon-αb. Twenty-two patients withchronic hepatitis C were enrolled into the study andtreated with amantadine 100 mg orally twice daily forsix months. Control groups included the same cohort followed off therapy for 29-36months or during therapy with interferon. Serum alanineaminotransferase (ALT) values decreased in 64% (P =0.01) of patients with amantadine therapy compared to intervals without therapy or to interferontherapy. Twenty-seven percent of patients treated withamantadine had normalization of ALT values and loss ofHCV RNA after six months while 18% achieved a sustained response with loss of HCV RNA by PCRsix months after discontinuation of amantadine. Therapywith amantadine improved both biochemical andvirological markers in patients with hepatitis C who had previously not responded to treatment withinterferon.
