Description

包含决奈达隆的药物组合物
技术领域
本发明涉及一种包含决奈达隆或其药学上可接受的盐、两亲性脂质 表面活性剂和磷脂的药物组合物。 背景技术
决奈达隆 (Dronedarone) 化学名为 2-正丁基 -3[4-(3-二 -正丁基-氨 基丙氧基)苯甲酰基] -5-甲基磺胺苯并呋喃, 分子式 C31H44N205S, 分子 量 556.765。
盐酸决奈达隆是由赛诺菲-先德纳宝公司(Sanofi-Synthelabo)最新 开发的治疗心律失常药物。 本品为不含碘的苯并呋喃类衍生物, 结构 和特征与胺碘酮类似, 但决奈达隆不含碘, 亲脂性较低, 因此既保持 了胺碘酮的疗效, 又没有胺碘酮的心外不良反应, 且半衰期为 1~2天, 更便于调整药物剂量。
盐酸决奈达隆在含水介质中溶解度很低, 特别的是它的溶解度在 室温下成 pH 依赖性, 在 pH值 3~5 的范围内有很大溶解度, 约是 l-2mg/ml, 在 pH约 6至 7下溶解度变的很低, 因为他在 pH=7下溶解 度只有 10 g/ml。
由于盐酸决奈达隆的溶解性低这一特点, 导致其通过胃肠道给药 的生物利用率低, 因为从胃到肠道的过程是一个 pH逐渐升高的过程, 这意味着盐酸决奈达隆的溶解度逐渐降低, 这就导致盐酸决奈达隆在 肠道较高的 pH环境下无法从固体制剂中溶出或溶出度很低。为提高盐 酸决奈达隆的生物利用度, 必须找到能提高盐酸决奈达隆溶出度途径。
US20040044070 公开了盐酸决奈达隆的注射剂。 此发明在缓冲系 统 (pH值范围为 3~5 ) 中加入了 β-环糊精衍生物, 从而提高了有效成 分的溶解度。 但是这种调高盐酸决奈达隆的溶解度方法, 制造过程复 杂, 而且稳定性可能较差。
专利 ZL98808158.X 公开了一种含苯并呋喃衍生物的固体药物组 合物, 该发明发现非离子型表面活性剂, 尤其是泊洛沙姆类非离子型 表面活性剂, 可以使溶解于 ρΗ4.5左右的溶液中的活性成分, 在经高 pH溶液稀释后, 能保持在 pH6-7溶液中, 基本不会受 pH升高的影响 而析出沉淀, 从而提高盐酸决奈达隆在空腹下的生物利用度。 该专利 说明书中所述的筛选过程可以看出, 虽然一系列的非离子型表面活性 剂的使用, 均能提高盐酸决奈达隆的在溶液中的保持能力, 但是, 仅 仅泊洛沙姆 407在用量不大的情况下, 可显示出较明显的效果。 而其 它种类的表面活性剂均需要较大的用量。
另外, 据不完全统计, 大约有 40%的新药均存在溶解度低的问题, 这类药口服给药, 经常存在生物利用度低、 个体差异大等问题。 为了 解决这一问题, 近年来, 采用脂质基质, 特别是具有自乳化能力的两 亲性脂质表面活性剂, 来改善难溶性药物的生物利用度, 已成为药剂 学领域的热点。 然而, 在实际应用中, 这类两亲性脂质表面活性剂的 用量往往较大, 在一定程度上限制了其应用。
本发明在以往经验基础上通过大量实验研究, 惊奇的发现在两亲 性脂质表面活性剂的存在下, 向处方中加入磷脂能大幅度提高盐酸决 奈达隆溶解度。 发明内容

通常, 本发明所述的药物组合物中的决奈达隆或其药学上可以接 受的盐, 如盐酸盐, 每个基本施用单位, 如每片或者每只胶囊, 或每 包颗粒剂, 含有的量可以从 50mg至 500mg, 优选 200mg至 400mg。
通常, 本发明所述的药物组合物中的两性脂质表面活性剂, 比例 以剂型中活性成份的重量计算是 1.25至 50%。 以片剂, 胶囊剂, 颗粒 剂等口服给药剂型的形式, 两亲性脂质表面活性剂的比例以剂型中活 性成份的重量计算是 1.5至 20%, 优选 2至 10%。
通常, 所述的药物组合物中, 磷脂的比例以剂型中活性成份的重 量计算是 0.5-15%。 以片剂, 胶囊剂, 颗粒剂等口服给药剂型的形式, 磷脂的比例以剂型中活性成分的重量计算是 1至 10%, 优选 2至 7.5% 除了所述的两亲性表面活性剂和磷脂外, 本发明的药物组合物还 可以含有口服形式的药物研究, 开发, 生产中通常使用的其他药物赋 形剂, 如微晶纤维素, 微粉硅胶, 交联羧甲基纤维素钠, 甲基纤维素, 羟乙基纤维素, 甲基羟丙基纤维素, 聚乙二醇 (例如聚乙二醇 6000), 乙烯吡咯垸酮聚合物或共聚物 (例如聚乙烯基吡咯垸酮) 和硬脂酸镁 等。
本发明的药物组合物可以通过适当的工艺方法制备:
a)将活性成分、两亲性脂质表面活性剂和磷脂溶解于有机溶剂或其 水溶液中, 所述有机溶剂选自乙醇、 甲醇、 二氯甲垸、 丙酮;

通过大量的研究和试验, 本发明的研究者惊奇的发现, 在两亲性脂 质表面活性剂的存在下, 向盐酸决奈达隆处方中加入适量的磷脂, 能 在原有基础上, 大幅提高药物的溶解度, 提高固体制剂的溶出度, 从 而提高药物的生物利用度。 本发明的有益效果为在药物组合物中加入 磷脂, 在降低两亲性脂质表面活性剂的用量的同时, 解决了盐酸决奈 达隆的溶解度问题。 具体实施方式

盐酸决奈达隆片
按专利 ZL98808158.X实施例 1处方工艺, 制备盐酸决奈达隆片。 实验例 1 : 在 pH6.7磷酸盐缓冲液中的保持试验
1)盐酸决奈达隆片 (相当于盐酸决奈达隆 426mg), 于 200ml量瓶 中, 加入 pH4.5的磷酸盐缓冲液使溶解并定容至刻度, 在 37°C保持 2 小时。
2)将此溶液用中性磷酸盐介质(Na2HP04+NaH2P04 )稀释到 1/10, 最终溶液的 pH是 6.7。 在 37°C保持 2小时后, 把溶液滤过 5.0um玻璃 纤维滤膜, 并用紫外分光光度计, 在 291nm波长处测定溶液中的活性 成分。

比较例 76
结论: 与实施例 2和实施例 8相比 (不含磷脂), 含磷脂的处方中 (实施例 3-7, 9-13 )盐酸决奈达隆的溶解度显著提高。与比较例相比, 含两亲性脂质表面活性剂和磷脂的处方, 能更显著的提高盐酸决奈达 隆在高 pH溶液中的保持能力。 实验例 2: 溶出度测定
参照中国药典 2005年版附录 XC, 采用桨法, 温度为 37°C±0.5°C, pH6.7的磷酸盐缓冲液 900ml为介质, 于 45分钟取样, 并用紫外分光 光度法测定 A值, 计算累积溶出百分率。

结论: 与实施例 2和实施例 8相比 (不含磷脂), 含磷脂的处方中 (实施例 3-7, 9-13 )盐酸决奈达隆在较高 pH介质中的溶出度显 著提高, 且一般都高于比较例溶出度。 实验例 3 : 生物利用度测定
血桨的采集: 39只比格犬每个实验例 3只,灌胃给予实验例 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 比较例的制剂, 给药剂量: 按 30mg/kg盐酸决奈达隆后, 于给药前(Oh)和给药后 1.0, 2.0, 3.0, 4.0, 5.0, 6.0, 7.0, 8.0, 9.0, 10.0, 11.0, 12.0, 13.0, 14.0, 16.0, 18.0, 20.0, 22.0, 24.0h于前肢静脉取血 2.0ml, 置肝素化试管中, 3000rpm 离心 10min, 分离血桨, -20°C保存待测。
血桨样品的测定:犬血桨样品经液-液萃取后,采用 LC/MS法测定。
