病毒是一种高度特异性微生物,在宿主细胞内利用细胞代谢系统进行增殖复制。因此抗病毒疗法必须针对病毒独有的关键与薄弱的复制步骤,避免损害宿主细胞。本文主要探索病毒性疾病的最佳疗法并为现用抗病毒药提供适应证。 目前所用的抗病毒药物,有阿糖腺苷、阿昔洛韦等。正在研究中的有磷酸阿糖腺苷、更昔洛韦、溴乙烯脱氧尿苷、三氮唑核苷和膦甲酸盐等,现分述如下。 阿糖腺苷(vidarabine,Ara-A)它是 The virus is a highly specific microorganism in the host cell using cell metabolism for proliferation and replication. Therefore, antiviral therapy must target the virus’s key and weak duplication steps to avoid damage to the host cell. This article explores the best treatment for viral diseases and provides indications of current antiviral drugs. Currently used antiviral drugs, there are vidarabine, acyclovir and so on. Are under study are phosphoglucoside, ganciclovir, vinyl ethylene deoxyuridine, ribavirin and foscarnet, are described below. It is vidarabine (Ara-A)
