title: Ribavirin analogs.
abstract: Ribavirin is ineffective against hepatitis C virus as mono-therapy but is critical in attaining both early virologic response and sustained virologic response when combined with pegylated interferon. Ribavirin has significant dose-limiting toxicities, the most important of which is hemolytic anemia. Taribavirin is a ribavirin pro-drug, which targets the liver and has less incidence of anemia, and it may be a promising alternative to ribavirin in the future.
