性状: 盐酸达卡他韦是一种白色至黄色粉末。 易溶于水或二甲基亚砜,微溶于乙醇(99.5)。 批准条件 制定药品风险管理计划,适当实施 药效药理 1. 作用机序 Daclatasville是HCV NS5A复制复合物的有效和选择性抑制剂。 HCV NS5A是涉及HCV复制和细胞内信号传导途径调节的多功能蛋白。 2. 抗病毒活性 Daclatasville在HCV复制子测定中对广泛的基因型具有影响。 对于基因型1a和1b,EC50值分别显示0.003至0.050nmol/L和0.001至0.009nmol/L的强抑制作用。 此外,其对基因型2a的EC 50值为0.034〜19nmol/L显示出抑制作用。 在使用HCV复制子测定的组合研究中,达克拉他维尔与阿斯匹克和干扰素α组合显示出添加剂或协同效应。 3. 药剂耐药性 在临床试验中共同施用达卡他韦盐酸盐和Asunaprevir靶向患有慢性丙型肝炎基因型1b中,在患者体内,一个无效的时间,一般耐取代达卡他韦(对NS5A-Y93和/或L31没有达到SVR24同时检测替硝唑(替代NS3-D168)的抗性替代物。 作为在Daclatasville存在下培养HCV复制子细胞的结果,发生对Daclatasville的抗性。作为基因型分析的结果,在NS5A的1至100个氨基酸中观察到显示针对Daclatasville的抗性表型的多个取代。对于基因型1b,在L31和Y93的氨基酸残基的频率观察到高电阻置换,氨基酸的情况下换人一个位置,EC50值小于30倍的野生型,在这两个位置的酸如果有替代(例如L31 V - Y 93 H),EC 50值超过野生型的1000倍。 4. 交差耐性 具有Daclatasville耐药替代品的HCV复制子对阿斯匹克,聚乙二醇化干扰素α具有足够的敏感性。 适应病症 慢性丙型肝炎或C型肝硬化血清群1(基因型1)病毒血症的改善 用法与用量 成人每天一次接受60毫克每日一次,作为daclatasville一次。 该药与阿斯匹韦联合使用,给药期为24周。 包装规格 片剂 60毫克:14片(14片×1)PTP

This medicine is used concomitantly with asunaprevir. It is usually used to treat chronic hepatitis C and compensated cirrhosis type C. Before using this medicine, be sure to tell your doctor and pharmacist •If you have previously experienced any allergic reactions (itch, rash, etc.) to any medicines. If you have liver dysfunction (referred to the precaution of concomitant medicine, asunaprevir). •If you are pregnant, possibly pregnant or breastfeeding. •If you are taking any other medicinal products. (Some medicines may interact to enhance or diminish medicinal effects. Beware of over-the-counter medicines and dietary supplements as well as other prescription medicines.) Dosing schedule (How to take this medicine) •Your dosing schedule prescribed by your doctor is <<to be written by a healthcare professional>> •In general, for adults, take 1 tablet (60 mg as daclatasvir) at a time, once a day. It is used concomitantly with asunaprevir 100 mg, and duration of medication is 24 weeks. Strictly follow the instructions. •If you missed a dose, and if you have more than 4 hours interval for the next dose, take the missed dose as soon as possible and continue your regular dosing schedule. If it is less than 4 hours interval for the next dose, skip the missed dose and continue your regular dosing schedule.
