简介

英文药名：SOVALDI Tablets(sofosbuvir) 中文药名：索非布韦片 生产厂家：吉利德科学ソバルディ錠400mg 药物分类名称：抗病毒剂 批准日期：2015年5月 商標名：SOVALDI Tablets 400mg 一般名：ソホスブビルSofosbuvir(JAN) 化学名：1-Methylethyl N-[(S)-{[(2R,3R,4R,5R)-5-(2,4-dioxo-3,4-dihydropyrimidin-1(2H)-yl)-4-fluoro-3-hydroxy-4-methyltetrahydrofuran-2-yl]methoxy｝phenoxyphosphoryl]-L-alaninate 分子式：C22H29FN3O9P 分子量：529.45 性　状 白色至微黄白色粉末可溶性易溶于甲醇，丙酮，乙腈或乙醇(99.5)，微溶于2-丙醇，微溶于乙酸乙酯，难溶于甲苯，二氯甲烷或庚烷。熔点约125°C分布系数log P = 1.62(1-辛醇/0.15mol/L氯化钾溶液)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Sofosvir是一种核苷酸前药，被转化为尿苷三磷酸类型，其是肝细胞中的活性代谢物，活性代谢物是丙型肝炎病毒(HCV)复制必需的HCV非结构蛋白5B， (NS5B)RNA依赖性RNA聚合酶。 来自HCV基因型1b，2a，3a和4a的活性代谢物对NS5B聚合酶的50%抑制浓度(IC50值)为0.36?3.3μmol/ L。 活性代谢物不抑制人类DNA和RNA聚合酶，并且不抑制线粒体的表达。 2. 体外抗HCV活性Sophosbuir抑制HCV基因型1-6复制子细胞中的RNA复制。 HCV基因型1a，1b，2a，2b，3a，4a，5a和6a的稳定表达Sofosvir对复制子细胞的50%有效浓度(EC 50值)为0.040,0.11,0.050,0.015,0.050,0.040,0.015和0.014μmol/ L)。野生型HCV基因型1a和1b，2A，2B，3A，4A，分别EC50值索非布韦用于瞬时表达的复制子细胞5a和6a 0.030,0.022,0.147,0.013,0.034,0.036,0.022和0.046μmol/L为26)。来自临床分离株的含有HCV基因型1a(67例)，1b(29例)，2(15例)和3a(106例)NS5B区域的复制子细胞的Sophosubville的ECso值(中位数)分别为0.062,0.10,0.029和0.081μmol/ L)。通过与Sofosvir和利巴韦林，干扰素α，NS5A抑制剂，NS3蛋白酶抑制剂或非核酸型NS5B抑制剂的组合观察到协同或协同的抗病毒活性。 3. 薬剤耐性在使用HCV基因型1至6的复制子细胞的Sophosubville的体外耐受性测试中，在所有基因型复制子细胞系中观察到NS5B区域中的S282T突变。 用S282T突变转染的所有基因型复制子细胞对Sophosvir的敏感性降低，与对应的野生型相比，S282T突变株的EC50值增加了2.4?18.1倍。 此外，Sofosvir的活性保留在含有与利巴韦林，非核酸NS5B抑制剂，NS3蛋白酶抑制剂或NS5A抑制剂的抗性相关的突变的复制子细胞中。所评估的国家III期临床试验的效力和安全性由代理和利巴韦林，病毒学复发患者的慢性丙型肝炎或5个例140的组合代偿性肝硬化型肝炎患者基因型2虽然承认，行政期间的突破不被承认。5例复发患者均未发现NS5B区S282T耐药突变株与Sophosbuir易感性突变株。四个外国相在慢性丙型肝炎或III期临床试验的目标代偿性肝硬化型肝炎患者基因型3，NS5B抑制剂核苷施用相关的突变(L159F和V321A)是病毒学治疗失败所观察到的和在得到NS5B核苷酸序列患者中检测到，对于这些突变的所有处理的例子的外观率为3.1%(17案件出555例)。患者为患有慢性丙型肝炎或代偿性肝硬化型肝炎患者基因型4 3次外国临床试验中，它不给药期间观察到的病毒学治疗失败，11例出111例给药后确认复发。然而，在这些患者的基线或复发处未检测到S282T抗性突变或给药相关突变(L159F和V321A)。 适应病症 慢性丙型肝炎或C型补偿性肝硬化病毒血症的改善(1)Celo组2(基因型2)(2)不属于血清组1(基因型1)或血清组2(基因型2)的患者 用法与用量 1.对于Celo组2(基因型2)：与利巴韦林组合，通常成人每天接受400mg作为Sophosbuir，持续12周。 2.如果不符合Cerro组1(基因型1)或Celo组2(基因型2)：与利巴韦林组合，通常成人每天接受400mg作为Sophosbuir，持续24周。 包装规格 片剂400mg：28片，14片(7片×2)PTP 制造厂商吉利德科学公司提示：以上中文资料不够完整，使用者以原处方资料为准。
