Hepatitis C virus infection affects around 3% of the world population or approximately 160 million people. A variable proportion (5% to 40%) of the infected people develop clinical symptoms. Hence, hepatitis C virus is a leading cause of liver-related morbidity and mortality with hepatic fibrosis, end-stage liver cirrhosis, and hepatocellular carcinoma as the dominant clinical sequelae. Combination therapy with pegylated (peg) interferon-alpha and ribavirin achieves sustained virological response (that is, undetectable hepatitis C virus RNA in serum by sensitivity testing six months after the end of treatment) in approximately 40% to 80% of treated patients, depending on viral genotype. Recently, a new class of drugs have emerged for hepatitis C infection, the direct acting antivirals, which in combination with standard therapy or alone can lead to sustained virological response in 80% or more of treated patients. Aminoadamantanes, mostly amantadine, are antiviral drugs used for the treatment of patients with chronic hepatitis C. We have previously systematically reviewed amantadine versus placebo or no intervention and found no significant effects of the amantadine on all-cause mortality or liver-related morbidity and on adverse events in patients with hepatitis C. Overall, we did not observe a significant effect of amantadine on sustained virological response. In this review, we systematically review aminoadamantanes versus other antiviral drugs.
