Description

一种稀释稳定性好的替尼泊苷注射用溶液及其制备方法 技术领域
本发明属于药物制剂技术领域，具体涉及一种稀释稳定性好的一种替尼泊苷注射用溶液及其制备方法。
背景技术
替尼泊苷(Teniposide，Vumon，VM-26)别名：威猛、维埃坶26、足叶毒硫花亚甲基葡萄糖苷、邦莱、鬼臼噻吩苷，是一种鬼臼毒素的半合成衍生物，属于植物来源的抗肿瘤药物。它是周期特异性细胞毒药物，抑制DNA拓扑异构酶Ⅱ，导致双链或单链破坏使细胞有丝分裂停止于S晚期或G 2前期，从而阻碍肿瘤细胞分裂，抑制肿瘤生长。替尼泊苷疗效显著，其生物活性是同类型药物依托泊苷的5～10倍，且临床资料表明替尼泊苷副作用少，毒性小，对肝、肾功能无明显影响。由于替尼泊苷具有较广谱的抗肿瘤活性，临床上通常与其它抗癌药物联合应用：主要用于恶性淋巴瘤、霍奇金氏病、急性淋巴细胞性白血病、胶质母细胞瘤、空管膜瘤、星形细胞瘤、膀胱癌、神经母细胞瘤和儿童的其它实体瘤。也用于治疗小细胞肺癌、卵巢癌、乳腺癌、多发性骨髓瘤、非小细胞肺癌等；更因其中性亲脂特性，能通过血脑屏障，目前已成为临床治疗脑瘤的首选化疗药物之一。1992年替尼泊苷注射液被美国FDA正式批准用于小儿急性淋巴细胞白血病化疗，商品名为VUMON(卫萌)。我国在21世纪初仿制成功，其商品名为邦莱。
由于替尼泊苷本身几乎不溶于水，必须溶于有机溶媒溶解，而且要加入表面活性剂来增溶。市售制剂的处方组成为：每支安瓿(5ml)含替尼泊苷50mg，苯甲醇150mg，N，N-二甲基乙酰胺300mg，聚氧乙烯蓖麻油(Cremophor EL)2.5g，42.7％(v/v)的无水乙醇。临床单独使用时按体表面积50～100mg/m2给药，用5％的葡萄糖溶液或生理盐水稀释后静滴。市售制剂在临床使用过程中存在的问题主要是处方中含有大量的聚氧乙烯蓖麻油，使用后可引起体内组胺释放，而引起严重的过敏反应。这些过敏反应包括支气管痉挛、呼吸急促、疲倦、低血压等。为此，医生在医嘱前必须了解病人的过敏史，如是否对替尼泊苷或蓖麻油等过敏；在临床使用时，医务人员需密切观察病人的情况，必要时使用抗组胺药物以减轻聚氧乙烯蓖麻油造成的严重过敏反应，从而导致临床上应用起来非常不方便，给病人带来很大的痛苦，顺应性差。而聚氧乙烯蓖麻油在接触聚氯乙烯塑料制成的容器、注射剂、输液袋时会浸出增塑剂邻苯 二甲酸二乙酯，导致毒性反应。市售注射剂中含有的苯甲醇可能造成新生儿的损害，禁止用于儿童肌肉注射。市售注射剂在稀释时稳定性差，往往会析出晶体，形成细小沉淀，堵塞病人局部血管。浓度为1mg/mL的替尼泊苷溶液，贮存于室温和普通日关灯下必须要4h内使用完，以减小沉淀发生的可能性。稀释后的注射液在长时间滴注过程中也常常出现沉淀现象，滴注过程中需要不时观察沉淀状况。
近年来，国内外药学工作者致力于研究减少或替代聚氧乙烯蓖麻油，使用的新型给药系统，以提高药物疗效，降低毒副作用。如用于全身给药的脂质体、磷脂复合物、含吐温的药物组合物、乳剂，供局部给药的微球制剂和凝胶制剂，供口服给药的微乳制剂等。但这些新的给药系统还是存在诸如使用表面活性剂(聚氧乙烯蓖麻油或吐温80)的毒性、成本高、制备工艺复杂等问题。
