一般名 リトナビル (Ritonavir) [JAN] 化学名 (+)-5-thiazolylmethyl[(αS )-α-[(1S , 3S )-1-hydroxy-3-[(2S )-2-[3-[(2-isopropyl-4-thiazolyl) methyl]-3-methylureido]-3-methylbutyramido]-4-phenylbutyl] phenethyl] carbamate 分子式 C37H48N6O5S2 分子量 720.94 性状 白色到浅黄棕色粉末,有些还包括软质。 药效药理 1. 作用机序 本剂是洛匹那韦和利托那韦的制剂。洛匹那韦抑制HIV蛋白酶的活性,通过抑制由HIV蛋白酶多聚在gag-POL的裂解,抑制产生成熟的HIV感染性。利托竞争由CYP3A抑制洛匹那韦的代谢,导致增加洛匹那韦的血液水平。这种药物的抗病毒活性是洛匹那韦(见“药代动力学”)。 本剂对HIV蛋白酶的选择性亲和力,它显示了对人的天冬氨酸蛋白酶的小的抑制作用。 2. 抗病毒活性(体外) 洛匹那韦的抗病毒作用在淋巴母细胞系和感染的临床分离株艾滋病毒标准株后早期感染的外周血淋巴细胞。在人类中无血清的,洛匹那韦的EC50为5种HIV-1的标准菌株的平均为10〜27纳米(0.006〜0.017μg/ mL)的7),平均的六种类型的洛匹那韦的抗HIV-1临床分离株EC50为4〜11nM(0.003〜0.007μg/ mL)中。在50%人血清的平均洛匹那韦的存在下对HIV-1标准株的EC50是65〜289nM(0.04〜0.18μg/ mL)中,在效力下降7〜11倍,观察。 3. 耐药性 敏感具有降低的洛匹那韦,洛匹那韦分离的HIV-1变体单独或在洛匹那韦和利托那韦的血液浓度的存在下,在临床给药时的HIV-1的体外继代进行。了检查表型和传代分离株的基因型,利托那韦的存在有人提议对耐洛匹那韦株的出现没有影响(体外)。 交叉耐药: HIV蛋白酶抑制剂(PI)之间观察到的交叉耐药性是变化的。关于病毒的交叉耐药性与由这种药物的治疗敏感性降低洛匹那韦信息尚未几乎获得。 此代理从四个患者PI使用历史,承认中洛匹那韦,茚地那韦,或交叉耐药性的表型电阻的增大获得了上届政府分离利托那韦已经保持了奈非那韦,交叉耐药这种药物的给药后收购。所有这是反弹或没有维持易感性安普那韦足够的病毒,仍然观察到(高达99倍,洛匹那韦,在安普那韦高达8.5倍)的弱灵敏度的降低。谁经历病毒反弹的科目,从科目沙奎没有经验得出两种菌株保持着易感性沙奎那韦。 在抗逆转录病毒治疗经验的患者抗病毒作用减少谁开始的联合治疗,包括洛匹那韦,利托那韦和基因型与相关: 在HIV蛋白酶的氨基酸替换(L10F/I/ R/V,K20M/N/R,L24I,L33F,M36I,I47V,G48V,I54L/T/V,V82A/C/F/S/T,I84V)3已经发现,影响这种药物的病毒学响应于存在或更多。在联合疗法中与HIV蛋白酶抑制剂(PI)抗性突变病毒学应答之间关系的速度在多个药物临床试验是如下的。(见药理学表) HIV蛋白酶抑制剂(PI)中所使用的示例的抗病毒活性: 它是在体外对洛匹那韦的敏感性降低的临床意义,这种药物的施用,尽管在血液处理由多个PI的向谁超过病毒的1,000copies/毫升,在56例患者的HIV RNA的量它是评价基因型和表型。反对开始隔离56株洛匹那韦的EC50为0.5〜96倍的野生菌株的EC50。药物48周,依法韦仑和核苷逆转录酶抑制剂的给药后,患者血液中HIV RNA水平大于400copies等于或小于/毫升,开始洛匹那韦的敏感性的10倍或更小,10倍的超40折以下,和93%,分别在该基团的例(25/27),73%(11/15)的40倍以上,这是25%(2/8)。此外,患者血液中的HIV RNA水平大于在病人洛匹那敏组的开始在这些50copies/毫升等于或更小,分别为81%(22/27),60%(9/15),25%(2/8)。 本剂在管理的耐药病毒的选择: 在II期临床试验为227箱子抗逆转录病毒治疗经验的人,HIV蛋白酶抑制剂药物(PI)已经用一个例子来的主题,服用此药一段12-100周量化后的病毒载量(>400copies四例的患者中相比,在试验开始分离/毫升)分离物,易感性洛匹那韦已显著减少。这四个患者都在试验开始时的分离物,使用PI抗性相关的突变,观察至少四个位置。此外,病毒反弹后,在所有的菌株的突变数增加了,也包括带有PI抗性相关的突变。然而,在该药物的患者的施用,由于此时的数据不足的突变模式是不可能的,以确定是否由于洛匹那韦。 适应病症 HIV感染症 用法用量 成人:一次400毫克100毫克·一(2片),每日两次或一次口500mg·对于给药一次口服,每天200毫克(4粒)。 但应注意的是,以上的儿童体重40千克可以一次为400mg给药·100毫克一(2片),每天两次口服。 这种药物可以与或不与食物施用 包装规格 组合片剂: 200mg/50mg/片×120片×1瓶
