药效药理
通过用利巴韦林和干扰素α-2b或PEG-IFNα-2b的组合，抗病毒效果增强。虽然没有详细利巴韦林的作用机理显然，同时抑制由鸟苷三磷酸的RNA的HCV衍生的RNA依赖性RNA聚合酶的摄取，通过被掺入丙型肝炎病毒RNA，指标和抗HCV活性的可以想象的。
(1) 抗HCV效果（抗HCV密切相关的病毒的抗病毒活性）
病毒性腹泻病毒密切相关的HCV病毒，利巴韦林显示出抗病毒效果，通过与IFN.alpha-2b或PEG-IFNα-2b被增强的组合作用（体外）。
(2) 抗病毒机制作用
利巴韦林是磷酸在细胞中由三磷酸鸟苷的RNA（体外）抑制HCV衍生的RNA依赖性RNA聚合酶的摄取。此外，利巴韦林三磷酸酯是由丙型肝炎病毒衍生的RNA依赖性RNA聚合酶掺入RNA的RNA的生产过程中，这被认为是破坏病毒基因组（体外）。
