Hepatitis C virus (HCV) is an enveloped, single-stranded, positive-sense RNA virus in the Flaviviridae family and is the leading cause of cirrhosis and need for liver transplantation. Ribavirin is a nucleoside analogue and broad spectrum antiviral agent that is used with pegylated IFN (Peg-IFN) for HCV treatment. Although ribavirin does not have significant antiviral effect when used alone, it does reduce the number of break-throughs and relapses when used in combination with Peg-IFN. In a mouse model, ribavirin treatment inhibited macrophage inflammatory cytokine response resulting in reduction in alanine aminotransferase (ALT) and histological improvement suggesting ribavirin may act on HCV via an immunomodulatory route. Studies combining IFN-α (used for the treatment of HCV) and ribavirin for 24 or 48 weeks showed increasing proportion of SVR (sustained virologic response) with longer duration and addition of ribavirin suggesting the important role ribavirin plays in improving SVR[3].
作用机制
By depleting endogenous GTP, ribavirin is preferentially incorporated into the growing HCV viral strand leading to reduced viral replication[3].
