Description

一种提髙缺氧耐受力的口服药物组合物
技术领域
本发明涉及药物制剂领域, 具体地说, 涉及一种提高缺氧耐受力的口服药 物组合物。
技术背景
缺氧是指因组织的氧气供应不足或用氧障碍, 而导致组织的代谢、功能和形 态结构发生异常变化的病理过程。缺氧可分为低张性缺氧、贫血性缺氧、循环性 缺氧、组织性缺氧四种类型, 其中贫血性缺氧和组织性缺氧属于用氧障碍, 低张 性缺氧和循环性缺氧属于氧气供应不足。
缺氧产生的大量自由基破坏线粒体膜的稳定性,导致机体组织功能和结构受 损以及能量代谢障碍, 临床表现为头晕、 头痛、 耳鸣、 眼花、 四肢软弱无力、 运 动能力下降、 思维迟钝、 记忆力下降、 恶心、 呕吐、 心慌、 气短、 呼吸急促、 心 跳快速无力等一般性的缺氧表现,也可以是心肌梗死、心绞痛、肺水肿、脑水肿、 休克、 呼吸衰竭、 脑卒中、 视神经损伤和脑神经损伤等严重型疾病。
提高缺氧耐受力的药物目前临床最常用的是利尿药如乙酰唑胺,另外还有肾 上腺皮质激素类药物如地塞米松, 氨茶碱等, 但这些药由于其毒副作用, 而不能 长期使用, 如乙酰唑胺长期应用易造成机体电解质紊乱等不良反应。此外, 常用 含红景天的中药制剂进行缺氧的预防和治疗,这类中药缓释剂能够辅助提高机体 对缺氧的适应性,降低应激反应来提高缺氧耐受力的效果,但该类中药起效缓慢, 效果也有限。 中国专利申请号 200310104871. X公开了左卡尼汀具有预防和治疗 高原病的作用, 但目前未见应用于临床的报道。
显然, 目前市场上仍然缺乏一种可长期应用、无明显不良反应、可用于预防 和治疗相结合的、 有效提高缺氧耐受力的药物。
发明内容
本发明的目的之一是提供一种临床使用方便的、可口服的、能够有效提高缺 氧耐受力的口服药物组合物,该药物组合物包括活性成分左卡尼汀或其衍生物或 其可药用盐, 活性成分曲美他嗪或其可药用盐和可药用辅料, 其中左卡尼汀或 其衍生物或其可药用盐与曲美他嗪或其可药用盐的重量比为 100 : 1。
本发明的目的之二是提供上述口服药物组合物在制备提高缺氧耐受力的药 物中的用途。 本发明的目的之三是提供上述口服药物组合物在制备提高血氧饱和度的药 物中的用途。
本发明的研究者经过大量的动物实验,意外地发现将曲美他嗪或其可药用盐 与左卡尼汀或其衍生物或其可药用盐按照一定比例联合给药或组合成组合物,能 够提高缺氧大鼠血氧饱和度, 延长小鼠在缺氧条件下的存活时间。

实施例四 普通片制剂开发辅料的筛选研究
根据左卡尼汀的理化性质以及剂型的特点,左卡尼汀是极易吸湿的鳞片状晶 体,应选择具有抗吸湿性的缓释辅料,本发明人通过大量药剂实验筛选出的辅料 包括微晶纤维素、 碳酸钙、 交联聚维酮、 滑石粉等, 其中微晶纤维素和碳酸钙是 赋形剂, 交联聚维酮是崩解剂,滑石粉可以作为骨架材料增加颗粒和片剂的可成 型性, 也可以作为润滑剂防止压片过程中的粘冲。
赋形剂优选微晶纤维素和碳酸钙,其重量比直接决定了片剂的可压性,本发 明人从实际制剂研发工艺过程考察, 在固定活性成分、 其他辅料比例的基础上, 详细研究了关键辅料微晶纤维素和碳酸钙不同比例情况下,颗粒的成型性, 片剂 的成型性的差别, 最终确定了微晶纤维素和碳酸钙的比例范围, 结果见表 5。

实施例五颗粒剂制剂开发辅料筛选研究
根据左卡尼汀的理化性质以及剂型的特点,左卡尼汀是极易吸湿的鳞片状晶 体,应选择具有抗吸湿性的缓释辅料,本发明人通过大量药剂实验筛选出的辅料 包括乳糖、 甘露醇、 乙醇、 柠檬酸等, 其中乳糖和甘露醇是赋形剂, 乙醇是粘合 剂, 柠檬酸是矫味剂。
赋形剂优选乳糖和甘露醇,本发明人从实际制剂研发工艺过程考察,在固定 活性成分、其他辅料比例的基础上,详细研究了关键辅料乳糖和甘露醇不同比例 情况下, 颗粒的成型性, 最终确定了乳糖和甘露醇的比例范围, 结果见表 6。
