本发明涉及医药技术领域, 具体地说, 是外用治疗癌性疼痛的药物组合物及其制备 方法, 特别是涉及一种以植物中草药为主要原料制成的外用治疗癌性疼痛的中药复方凝 胶及其制备方法。
背景技术
癌痛是恶性肿瘤常见的症状之一, 70%〜90%的中、 晚期癌症患者遭受不同程度的 疼痛困扰, 严重影响了患者的生活质量。 目前癌痛的西医治疗方法主要是在抗肿瘤治疗 基础上加药物三阶梯止痛法、 生物治疗、 神经阻滞治疗等。 尽管如此, 经过常规治疗仍 有 36%〜50% 的癌症患者忍受的疼痛程度足以影响他们的日常生活, 且主要的镇痛药物 (阿片类药物和非甾体类抗炎药物) 因其副作用而使临床应用受限。 目前药物是治疗癌性 疼痛的有效措施, 三阶梯止痛疗法作用速度快、 止痛力强, 但长期服用阿片类药物效果 欠佳且易产生如便秘、 恶心、 运动和认知障碍、 呼吸抑制、 依赖性等不良反应。
中医学以其独特的理论体系在治疗癌痛领域发挥了重要作用,特别是经过近 20年的 迅速发展, 形成了口服、 外用、 静脉给药、 吸入给药等多途径治疗方法, 同时开展了治 疗癌性疼痛的临床随机对照试验研究, 结果发现中药具有良好的镇痛效果。 长期大量口 服或静脉给药给患者带来不便, 且有可能对胃肠道产生不良影响, 近年来中医外治法治 疗癌性疼痛具有一定优势, 通过体表、 穴位、 直肠、 鼻腔等部位直接给药, 经过皮肤、 经络吸收使药达病所, 避免了药物对胃肠道的刺激, 提高了药物起效速度及其安全性和 患者的依从性; 具有止痛抑癌、 使用方便、 不良反应小、 无依赖性、 作用柔和等特点。
目前癌性疼痛治疗领域存在以下问题: (1 ) 西医治疗方法主要是在抗肿瘤治疗基础 上加药物三阶梯止痛法、 生物治疗、 神经阻滞治疗, 但是临床疗效并不理想; (2) 阿片 类药物是治疗癌性疼痛的主要药物, 而长期服用阿片类药物易产生如便秘、 恶心、 运动 和认知障碍、 呼吸抑制、 依赖性等不良反应; (3 ) 中药治疗癌性疼痛的主要给药方式为 口服和静脉给药, 长期大量口服或静脉给药给患者带来许多不便; (4) 癌性疼痛多发生 于晚期肿瘤患者, 在肿瘤治疗的基础上长期口服或静脉给药, 增加了患者的胃肠道负担 和身体负荷, 影响患者的生活质量; (5 ) 目前中药外用治疗癌性疼痛的药物多为膏剂、 散剂和酊剂等传统剂型, 限制了中医外治癌痛的发展, 需要进行剂型改革。
中国专利公开号 CN101433651A公开了一种治疗骨伤、 骨病、 关节炎、 外科疮疡的 纯中药制成巴布膏剂-肿痛贴, 由蒲公英、 葛根、 骨碎补、 救必应、 穿山龙、 灵芝等 19 种中药原料药组方, 原料药先粉碎, 经水提, 醇提等法分别提取, 浓縮成稠膏状, 并加 入辅型剂, 制成巴布剂型的"最新中药膏剂", 经临床观察, 对骨髓炎, 骨质坏死, 骨结 核, 晚期癌痛等病症有治愈作用。 中国专利公开号 CN 101670035A公开了治疗癌性疼痛 的中药组合物及其制备方法,由原料药鼠妇 3-5重量份、蚤休 4-重量份、荜拔 3-5重量份、 制白附子 3-6重量份、 制乳香 1-3重量份、 制天南星 2-6重量份制成, 具有良好的镇痛作 用,提高癌症患者的生活质量, 而且具有较好的抗癌作用。 但是关于一种外用治疗癌痛的 中药复方凝胶及其制备方法目前还未见报道。

( 1 ) 提取: 将中药配方中的所述 7味药材, 粉碎后以体积浓度为 60-80%乙醇回流 提取, 提取次数为 2〜3次, 每次加乙醇量为总体积的 6〜10倍量, 提取时间分别为 l〜3h., 提取液合并, 回收乙醇, 浓縮, 减压干燥至稠, 得药物提取浸膏;
(2)制剂: 称取卡波普 940均匀分散于适量蒸馏水中, 溶胀过夜; 将药物提取浸膏 以乙醇溶解, 在搅拌状态下加入卡波普 940中; 再依次加入氮酮、 丙二醇、 甘油, 搅拌 至混合均匀, 卡波普 940、 蒸馏水、 药物提取浸膏、 丙二醇、 甘油和氮酮的量比关系为: 0.6〜1.0: 80.0-90.0: 6.0〜8.0: 3.0-5.0: 1.0-3.0: 1.0〜3.0; 缓慢滴加三乙醇胺; 调 H值 至 6.0〜6.5, 搅拌均匀, 即得所述中药复方凝胶制剂 。
质量控制: 采用 LC/MS法对配方中延胡索的主要成分延胡索乙素的含量进行测定: 色谱柱: XTerraR MS C18column, 2.1mmx l50 mm, 5μηι,; 流动相: 甲醇: 水 (85:15, v/v); 流速: 0.3mL/min; 柱温: 40 °C ; 进样量: 5 L; 运行时间: 3min。 质谱条件: 离 子源为 ESI源; 负离子模式检测; 扫描方式为多反应监测 (MRM); 用于定量分析的离 子为 m/z=165 ; 毛细管电压 4000V; 干燥气流速 8L/min; 干燥气温度 350°C ; 雾化器压力 40psi; 裂解器电压 105eV; 碰撞能量为 33。

本实施例配方是由主药穿山龙, 配伍行气止痛药延胡索、 川楝子, 藤类药海风藤、 青风藤以及树脂类药乳香、 没药组成。 现就其成份的药理作用予以阐述。
穿山龙: 根据中医理论, 具有舒筋活血, 通络止痛之功;
延胡索、 川楝子: 有行气止痛的作用, 现代药理研究表明延胡索具有镇痛、 镇静、 安定和催眠作用;
海风藤、 络石藤: 依据中医取象比类的理论, 藤类药物具有通络止痛的良好效果; 乳香、 没药: 具有行气活血, 消肿止痛的作用。
全方共奏行气活血、 通络止痛之功。 "不通则痛"和 "不荣则痛"是癌性疼痛主要的病因病机。 本虚标实为癌痛的病理 特征, 全身虚, 局部实, 多是因虚而得癌病, 因实而致癌痛。 风寒闭阻、 热毒内蕴、 痰 湿结聚、 气滞血瘀、 阴阳亏虚等为癌痛的基本病机,它们常相互影响、 相互转化, 互为因 果而成虚实夹杂、 寒热相间的证候。 中医药外治法主要的组方思路为: 理气行气、 活血 化瘀、 解毒散结、 通络止痛, 是中药治疗癌痛最常用的方法之一。 该方行气活血、 通络 止痛、 寒热并用, 符合癌性疼痛的病机和外治组方思路。
综上所述, 为该配方外用治疗癌性疼痛取得确切疗效提供了理论依据。
发明人经多年对龙藤通络凝胶进行质量控制和安全性评价, 并对其外用治疗大鼠骨 癌痛模型进行实验研究, 结果表明龙藤通络凝胶质量稳定可靠, 龙藤通络凝胶 1 号、 2 号和 3号方均可以减轻骨癌痛大鼠机械痛和热痛, 且以龙藤通络凝胶 2号方疗效最佳。 龙藤通络凝胶 2号方能够降低骨癌痛大鼠外周血中 I型胶原吡啶交联终肽 (ICTP) 和骨 特异性碱性磷酸酶 (BAP) 的水平, 抑制破骨细胞和成骨细胞活性。 病理学和生化检查 研究表明龙藤通络凝胶 2号方外用安全, 未见明显毒副作用。 这些研究为该配方治疗癌 性疼痛取得良好疗效提供了实验依据, 具体实验数据见表 1、 表 2、 表 3和说明书附图。
