一种稳定的青蒿琥酯盐酸阿莫地喹复方片及其制备方法
技术领域
本发明属于药物制剂领域, 具体涉及复方片剂的制备, 更具体地涉及一种 稳定的青蒿琥酯与盐酸阿莫地喹复方片及其制备工艺。 背景技术
青蒿琥酯主要作用于疟原虫红内期无线体, 作用方式主要是干扰表膜一线 粒体的功能, 其有如下作用特点: 1 )对耐氯喹恶性疟疾有效; 2 ) 可快速杀灭 疟原虫红内期无性体, 控制疟疾症状; 3 ) 与其他抗疟药相比, 该产品副作用 小。 但是该产品半衰期短, 短疗程治疗, 杀虫不彻底, 原虫复燃率高, 需延长 疗程 (6-7 天) 才能彻底杀灭疟原虫而提高治愈率。 并且, 它与其他抗疟药相 比, 价格比较贵, 临床应用受到一定限制。
阿莫地喹结构与作用和氯喹相似, 能有效杀灭红内期内各种虐原虫无性 体, 对间日疟、 三日疟和卵形疟的成熟配子体亦有一定作用, 但对肝细胞内的 休眠子红外期疟原虫则无效。 其有如下作用特点: 1 )对耐氯喹恶性疟疾有效; 2 ) 对血内各种疟原虫的无性体均有较强的杀灭作用, 可迅速控制临床症状, 对间日疟、 三日疟和卵形疟的成熟配子体和未成熟的恶性疟原虫配子体亦有杀 灭作用; 3 ) 价格低廉, 用于治疗疟疾时疗效确切且耐受性良好, 所以在非洲 地区仍将其作为一线抗疟治疗用药。 但是, 该产品毒性比其他抗疟药大。
青蒿琥酯与阿莫地喹复方制剂是目前最有效的抗疟疾药物, 其治疗疟疾的 治愈率可达到 95%, 且起效时间比单方制剂要短。 可显著提高疟疾疗效, 限制 耐药的传播。 WHO推荐以青蒿素为基础的联合用药 (ACT) 作为一线抗疟用 药, 它已被普遍认为是治疗恶性疟的最佳方案。 用于治疗各种疟疾, 尤其是治 疗对其它抗疟药 (如氯喹)产生耐药的恶性疟原虫引起的疟疾, 也用于疟疾的 急性发作, 具有良好的耐受性。 将青蒿琥酯和阿莫地喹制备成复方制剂, 可减 少联合用药过程中出现的错服药物现象 (尤其针对儿童), 在不改变药物原有 药物活性的基础上, 便于人们服用方便, 同时减少剂量, 降低副作用。 然而, 由于青蒿琥酯在酸性或碱性条件下均易于水解, 在现有的青蒿琥酯 与阿莫地喹复方制剂的制备过程中, 常发生如下反应-
H+
C19H2808(青蒿琥酯) ► C15H2405 (双氢青蒿素) +C4H604(琥珀酸)
OH"
从而导致复方制剂的不稳定性。
目前上市的制剂 Coarsucam®采用双层片的剂型以解决制剂不稳定的问 题, 但由于青蒿琥酯和阿莫地喹需分两层分别打片, 制备工艺较为复杂。
为了既解决复方制剂稳定性的问题, 又简化工艺, 本发明对配方和工艺进 行了改良, 以克服现有技术的上述不足之处。
