本发明涉及一种式(I)化合物盐酸盐和葡萄糖的水制剂、该制剂的 制备方法以及该制剂在制备用于预防或治疗人类或动物细菌感染的药 物中的应用。 背景技术
至 60年代第一个喹诺酮类合成抗生素上市以来, 此类药物得到了 迅速的发展。 但是随着氟喹诺酮类药物日益广泛的应用, 某些细菌如 金黄色葡萄球菌、 绿脓杆菌等对以环丙沙星为首的现有品种产生了耐 药性。 另外, 部分喹诺酮品种存在较严重的副作用, 因此, 较早的第 二代乃至第三代喹诺酮类抗生素在临床上的应用已经开始受到限制。
本发明所述的是一种式 (I)化合物, 其具有有效广谱抗细菌感染作 用, 所述式 (I)化合物有如下所示的结构式:
Figure imgf000003_0001
(9) -氟- 2, 3 -二氢 -3-甲基- 8-氨基- 10- (4-甲基 -1-呱嗪基 ) -7 -氧 代 -7H-吡啶并 [1, 2, 3- de] - [1, 4]苯并噁嗪- 6-羧酸
专利 CN1459288A记载了一种环磷腺苷葡胺大输液制剂及其制备方 法以及该大输液制剂中环磷腺苷葡胺含量测定方法。 该发明的技术方 案为每 100毫升制剂中含有葡萄糖 4. 5-5. 5克, 环磷腺苷葡胺 54 - 66 毫克, 其余为注射用水, pH范围为 3. 5〜5. 5, 该技术方案确定了环磷 腺苷葡胺大输液制剂稳定的关键条件 PH值范围及其大输液制剂制备方 法、 并解决了环磷腺苷葡胺含量测定方法, 有利于对环磷腺苷葡胺大 输液制剂生产质量的控制, 从而制定合适的生产方法, 使环磷腺苷葡 胺大输液制剂得以工业化大批量生产成为可能。
中国专利 CN1562029A记载了一种依诺沙星静脉注射液, 每升注射 液含有 10〜60g依诺沙星、 25. 2〜36. 9g葡萄糖酸- S -内酯, 其余为注 射用水。 其制法为: 将依诺沙星和 D-葡萄糖酸- δ -内酯混合, 加入注 射用水中, 加热至 55°C〜60°C, 搅拌, 至依诺沙星和 D-葡萄糖酸- δ - 内酯混合物全部溶解, 然后加入注射用水至 1 升, 搅匀, 加针用活性 炭搅拌均匀, 静置后过滤除去活性炭, 过滤至澄明, 灌装, 封口, 流 通蒸汽灭菌即得述依诺沙星静脉注射液。 本发明采用 葡萄糖酸- δ - 内酯与依诺沙星混合于水中能使依诺沙星完全溶解, 由此得到的依诺 沙星静脉注射液不仅澄明度高, 外观几乎无色或微黄色, 而且可减轻 或消除依诺沙星的光敏毒性而引起的皮肤红肿、 疼痛甚至静脉炎, 使 用安全且无不良反应。
专利 CN1615869A—种盐酸氟桂利嗪注射液及其制备方法, 由下列 组分构成: 盐酸氟桂利嗪 (g) : O. lmol/L氢氧化钠溶液 (ml) : 注射用水 或 5%或 10%葡萄糖溶液 (ml)为 1〜5: 0〜250: 50000; 或盐酸氟桂利嗪 (g) : 0. lmol/L盐酸(ml) : 5%或 10%葡萄糖溶液 (ml)为 1〜5: 0〜600: 1000000 制备方法采用制备工艺解决盐酸氟桂利嗪的溶解问题, 即在 低温下, 先将盐酸氟桂利嗪加入到溶液中, 搅拌后使盐酸氟桂利嗪分 散在溶液中, 再加热至较高的温度, 使盐酸氟桂利嗪充分溶解, 所以 注射液中不含有增溶剂和止痛剂, 因而对血管及肌肉无不良刺激, 使 用方便、 安全, 疗效显著。
上述药物化合物与葡萄糖制备的制剂, 克服了活性化合物在制剂 上的一些不足之处, 但是在将式 (I)化合物的盐酸盐制备成液体制剂 时, 其非常不稳定性, 很容易降解或分解, 比如在光照下。 这是因为 式 (I)化合物中含有类似的 -酮酸结构, 在酸性环境中稳定性差, 且 在长时间光照下易脱羧, 从而失去活性; 并且受 5-氨基给电子基的影 响, 式(I)化合物盐酸盐在长时间光照下羧基更容易失去, 导致式 (I) 化合物的含量、 ρΗ值和光透过率的降低。
因此, 我们需要通过一些方法提高式(I)化合物盐酸盐的水溶液稳 定性, 尤其是提供一种包含式 (I)化合物盐酸盐水溶液的液体制剂。
本申请人在经过长期认真的研究后, 意想不到地发现, 在一定浓 度的葡萄糖存在下, 可以显著抑制式 (I)化合物盐酸盐水溶液中的盐酸 盐化合物含量、 ρΗ值和光透过率的降低以及相关物质的形成, 尤其在 某一特定浓度的葡萄糖溶液可以阻止光照下式 (I)化合物盐酸盐的降 解。 因此, 在特定范围浓度葡萄糖存在下, 式 (I)化合物盐酸盐的水溶 液的稳定性得到显著的改善, 基于此, 完成了本发明。 发明内容

如果有医学上的需要, 本发明的水制剂中除了含有葡萄糖外, 还 含有其它可药用的添加剂, 如助溶剂、 缓冲组分、 防腐剂、 抗氧化剂 或稳定剂等。 例如可以加入钠盐、 钾盐、 钙盐和镁盐等, 以及它们的 氯化物、 碳酸盐、 硫酸盐、 乙酸盐、 葡萄糖酸盐、 乳酸盐、 苹果酸盐 和胃肠外给药领域所应用的其它常规辅料, 这些赋形剂或辅料都可以 任选地在调整水溶液的 pH值之前加入。
本发明的水制剂不仅可以全身使用例如注射或点滴, 也可以局部 使用如外用或喷洒。 例如, 本发明水制剂用作胃肠外给药药物, 特别 是用作治疗或预防细菌感染的药物。 胃肠外给药包括例如: 静脉内、 动脉内、 皮下、 肌肉内和腹膜内给药。 其中静脉内给药是最主要的给 药途径。最合适的剂量为 lOOmg/lOOml式 (I)化合物盐酸盐 (基于式 (I) 化合物的量), 每天静脉内输注 1次。 每天给药的输注体积应该不超过 500 - 600ml。
本发明还提供如上所述式 (I)化合物盐酸盐的水制剂在制备胃肠 外给药药物中的应用, 以及所述水制剂在制备用于预防或治疗人类或 动物细菌感染的药物中的应用。 在本发明的水制剂中, 葡萄糖的存在可以增强式(I)化合物盐酸盐 对光的稳定性, 尤其是减少式(I)化合物的 3位羧基的脱落, 以保持式 (I)化合物盐酸盐水溶液的稳定性。 我们观察到, 甚至葡萄糖浓度在 0. 10% (w/v)时, 就能观察到式(I)化合物盐酸盐的稳定效果, 当浓度 为 2. 0%-7. 0%(w/v)时, 其稳定效果特别好。 具体实施方式
如下将采用的实施例对本发明进行更详细地描述, 但本发明的内 容并不限于此。
本发明实施例所用的式(I)化合物盐酸盐由安徽环球药业有限公 司提供。 盐酸、 氢氧化钠、 葡萄糖都是国家规定的试剂级别。 使用的. 水是注射用水。 一般制备方法
本发明的下述实施例 1-12都是按照如下制备方法制备的: 称取一 定量的葡萄糖, 加注射用水溶解, 得到葡萄糖溶液, 加活性碳搅匀, 加热煮沸, 趁热过滤脱碳; 然后称取一定量的式 (I)化合物盐酸盐, 加 至上述溶液中, 搅拌溶解, 之后调节 pH值 (如采用 0. kiol/1的盐酸 水溶液), 最后加注射用水至全量, 搅拌、 过滤使之混匀。 然后加入适 量针用活性碳, 回滤, 过微孔滤膜(例如 0. 45 μ πι)于输液瓶中, 加塞, 轧铝盖, 加热灭菌 (例如 115°C、 32分钟) 即可。
以下实施例中式 (I)化合物盐酸盐 /葡萄糖水制剂中的式 (I)化合 物盐酸盐都是基于式(I)化合物计算的, 即称取 llOg式(I)化合物盐酸 盐相当于 100g式 (I)化合物, 例如实施例 3中 "式 (I)化合物盐酸盐 / 葡萄糖水制剂, 0. 1% (w/v) (lOOmg/lOOml) "是指式(I)化合物盐酸盐 在水溶液中含量是 0. 1%,即在 100ml水溶液中含有 lOOmg式(I)化合物, 其相对应的式(I)化合物盐酸盐质量为 110mg。 其它实施例以此类推

a.测定仪器:
UV - 1700紫光分光光度计(日本岛津公司) 紫外强度测定仪 (UVC-254) ;
紫外灯(120W), 波长: 200- 400皿, (重庆灯泡工业公司); 太阳光 (温度: 25- 35°C ; 天气: 晴; 强度, 大);
自然光(温度: 22 30°C ; 阳台边)。 b.测定波长的选择及稳定性试验
取不含葡萄糖的式(I)化合物盐酸盐水溶液为标准溶液, 并以蒸馏 水为空白, 在 200-400nm波长范围内扫描。 结果发现式(I)化合物盐酸 盐在 227、 297和 377mn有最大吸收,而杂质在 297nm左右有最大吸收, 所以最终选择 297 作为式 (I)化合物盐酸盐的测定波长。 此外, 将该 溶液置于室温避光处, 分别测定 0、 2和 4小时的吸光度, 均几乎无变 化, 表明该溶液稳定性良好。 c式(I)化合物盐酸盐水溶液在不同光照下的稳定性测定
精密吸取不含葡萄糖的式(I)化合物盐酸盐水溶液 lml, 置于紫外 光下照射, 并于不同的时间段 0、 1、 2、 3、 4 小时取适量稀释到浓度 约为 5 g/ml 的溶液, 测定吸光度, 计算含量及下降百分数。 同时吸 取不含葡萄糖的式(I)化合物盐酸盐水溶液, 分别置于太阳光、 自然光 下照射, 测定并计算含量以及下降百分比, 结果参见表 1。
由表 1的结果可以知道, 不含葡萄糖的式(I)化合物盐酸盐水溶液 在三种光源的照射下, 含量随时间的延长而下降。 在不含葡萄糖的式 (I)化合物盐酸盐水溶液置于光照下, 其降解的速度逐渐增加。 式(I) 化合物盐酸盐在光照下不稳定, 其降解产物可能引起临床的不良反应。

Figure imgf000014_0001
d.对照试验
(1)、 测试用样品的制备
对照品:制备式 (I)化合物盐酸盐 0. l% (w/v) (活性成分:基于式 (I) 化合物的量计)的注射用水的水制剂作为空白对照品——样品 1 ;
测试品:按照本发明实施例一般制备方法制备式(I)化合物盐酸盐 / 葡萄糖水制剂样品, 取一定量的葡萄糖, 在 80ml注射用水中加入不同 量的葡萄糖(分别为 0. lg、 0. 5g、 2. 0g、 4. 0g、 5. 0g、 6. Og, 7. Og或 10g), 作为样品 2-9。 然后分别加入式 (I)化合物盐酸盐 l lOmg (活性成 分: 相当于 lOOrng式 (I)化合物), 搅拌后使用调节 pH为 4. 0左右, 然 后分别加注射用水定容至 100ml, 准确取出 10ml置入测量瓶内, 以待 测定。
分别取对照品和测试品 10ml置于测量瓶中, 进行测定。
(2)测定方法
根据与上述 c (式(I)化合物盐酸盐水溶液在不同光照下的稳定性 测定)相似的方法, 将上述样品精密吸取 lml, 置于紫外光 (条件与上述 c—致)下照射,并于 4小时后取适量稀释到浓度约为 5 μ g/ml的溶液, 测定吸光度, 并计算含量及下降百分数, 测定并计算含量以及下降百 分比, 结果参见表 2。 表 2: 紫外光照下含葡萄糖的式(I)化合物盐酸盐水溶液的吸光度、 浓 度以及下降百分比
Figure imgf000015_0001
根据表 2的结果可以知道, 含葡萄糖的式 (I)化合物盐酸盐水溶液 在自然光的照射下, 含量随时间的延长而有所下降, 但下降的速度大 为减缓。 显而易见的是式(I)化合物盐酸盐水溶液加入葡萄糖后抑制了 由于照射引起的化学成分的改变, 如 pH值、 浓度下降百分比的降低都 证明了加入葡萄糖可以提高式 (I)化合物盐酸盐水溶液的稳定性。
同时, 从表 2的数据中我们可以看出, 当葡萄糖浓度在低至 0. 1% 时, 对式 (I)化合物盐酸盐水溶液稳定性影响就己经存在, 而其中样品 8的下降速度最低, 这意味着式(I)化合物盐酸盐水溶液中葡萄糖浓度 达到 7. 0%左右时效果最明显。不过也可以看出,当葡萄糖浓度超过 4. 0% 时同样也能观察到稳定的效果。
