It is known that kidney disease, repeated renal dialysis, and certain cancer therapies can cause iron deficiency. "Blood medicine,” means an agent that stimulates the formation of blood cells and/or increases the level of hemoglobin in the blood.
  • the treatment of iron deficiency can be divided into two categories: oral supplementation and injection supplementation.
  • the oral supplemental administration method is to improve the symptoms of iron deficiency by oral administration of a simple iron salt such as ferrous sulfate and ferrous gluconate. If oral supplementation does not achieve the desired results, consider the use of supplemental administration as the next stage of treatment, with intravenous and intramuscular injections being two common methods of administration.

Description

一种易复溶的铁 -糖类组合物及其制备方法 技术领域
本发明涉及一种粉末状药用组合物, 具体为包含有效治疗量的活性 药物成分氢氧化铁-糖复合物和至少一种添加剂的粉末组合物,以及制备 具有治疗活性的新型注射用铁 -糖类复合物的方法。该复合物可注射治疗 铁缺乏症。 该复合物可于给药前方便地复溶于水中。 背景技术
铁 -糖类复合物及其衍生物是 FDA批准的用于治疗铁缺乏症的几类 补血药物之一。 铁缺乏症是一种血液疾病, 可由先天性的基因缺陷或者 其他内科异常引起。 已知肾病、 重复肾透析以及某些癌症疗法均可引起 铁缺乏症。 "补血药,, 指可刺激血细胞的形成和 /或提高血液中血红蛋白 水平的试剂。
根据给药途径的不同, 铁缺乏症的治疗可分为两类: 口服补充给药 法及注射补充给药法。 口服补充给药法即患者通过口服硫酸亚铁和葡萄 糖酸亚铁之类的简单铁盐, 以改善铁缺乏症状。 若口服补充给药法无法 达到预期的效果, 则考虑将注射补充给药法作为下一阶段的治疗, 其中 静脉注射及肌肉注射为两种常用给药方法。
现已开发了多种注射治疗铁缺乏症的疗法。 为此, FDA批准了两类 化学药物。 第一类为右旋糖酐铁, 为氢氧化铁和葡聚糖的复合物。 一旦 注射进入人体, 右旋糖酐铁迅速被细胞吸收, 并分解成铁及葡聚糖两部 分, 然后进入不同的代谢途径。
由于右旋糖酐铁可在一些患者身上引起严重的副反应, 第二类注射 用补充剂一一铁-糖类复合物,作为治疗铁缺乏症更安全的药物就显得格 外有用。 不似含有多聚葡萄糖结构的右旋糖酐铁, 该铁-糖类复合物不含 多聚单糖。 目前市面上可见到的两类铁-糖类复合物, 均具有结合三价铁 离子的葡萄糖酸盐和 /或蔗糖所形成的骨架结构。 第一类铁-糖类复合物为葡萄糖酸铁钠 -蔗糖复合物 (SFGCS ) 。 SFGCS是一大分子复合物, 表观分子量大于 350,000道尔顿。 相比较而 言, 另一类铁 -糖类复合物则要小得多, 其表观分子量小于 80,000道尔 顿。 该类铁 -糖类复合物在化学上称为氢氧化铁-糖复合物 (FHSC ) 。
现有已公开的铁-糖类复合物的制备方法要么缺少最终的干燥步骤, 要么要求额外的纯化步骤, 以在干燥前充分除去辅料。 该额外的纯化步 骤不仅降低了总产率, 而且提高了生产总成本。 因此, 有必要改进工艺, 使该铁-糖类复合物在不除去辅料的情况下, 于反应完成后干燥成粉末。
在美国药典中对铁-糖类复合物, 尤其是铁-蔗糖复合物中 cr离子的 含量有一定的限量范围,如何控制 cr离子的含量却没有文献报道,我们 在研究铁 -糖类复合物尤其是铁-蔗糖复合物的过程中, 发现通过在制备 铁 -蔗糖复合物的过程中加入 NaCl达到控制 Cr离子含量的目的,从而完 成本发明。 发明内容
本发明的方法解决了上述问题,提供了一种制备铁-糖类复合物干燥 粉末的方法。 本发明的优点在于使得必需的盐或其他辅料, 这里主要指 无机氯化物, 尤其是 NaCl可以在干燥前加入到铁 -糖类复合物中。
一方面,该铁 -糖类复合物可在反应完成后在无须预先除去盐或其他 辅料的情况下进行干燥。 依此方案, 盐或其他辅料的浓度将在干燥后得 以保持。
本方法可适用于 SFGCS 及 FHSC这两类铁-糖类复合物, 以及它们 的衍生物和混合物。 由于铁-糖类复合物在溶液中不稳定, 以干燥粉末的 形式储存和运输这些化合物是有益的。虽然已有多种用于制备这两种铁- 糖类复合物的方法, 但却少有制备该类化合物干燥粉末的方法被公开。
可将确定、可重复剂量的必需盐或其他辅料加进最终的干燥产物中。 理论上, 这些非活性成分可在纯的活性药物成分干燥后添加。 然而, 在 干燥前引入这些非活性成分可使这些成分与活性药物成分混合得更均 匀。 在干燥前加入必需的辅料有其优点, 因为该辅料没有无菌要求。 这 一改进意义重大, 因其使得原料药制造商可以将该补血药制成易混合的 粉末, 非专利药制造商可于销售前方便地将该药物粉末复溶于水中。 在 原料药制成以后, 仅需添加纯化水。 由此, 本方法通过去除额外的纯化 操作步骤, 从而降低了出错的可能性。
在一实施方案中, 通过测定反应混合物中的盐含量, 以确定所需加 入的盐或辅料的量。 依本发明之方案, 盐及其它辅料与活性成分即铁- 糖类复合物一起进行干燥。 这里所称的盐主要指无机氯化物, 优选是 NaCL 这一改良的新方法使得原料药制造商能将补血药制成易混合的粉 末, 非专利药制造商可在交货用于临床使用前方便地将该粉末复溶于水 中。
本发明的目的是提供一种干燥粉末形式的药物组合物 , 其特征在于 包含有效治疗量的活性药物成分氢氧化铁-糖复合物和至少一种添加剂 以及任选的赋形剂, 其中添加剂可为无机氯化物, 如氯化钾、氯化钠等, 优选氯化钠。 氢氧化铁-糖复合物优选为氢氧化铁-蔗糖复合物或葡萄糖 酸铁钠 -蔗糖复合物。 其中, 氢氧化铁-蔗糖复合物的分子式为 [Na2Fe508(OH).3(H20)]nm(C12H22Ou), 其中 n为 1-30的任一整数, m为 1-360的任一整数。优选 n为 5-20的任一整数, m为 60-240的任一整数。 这里的氢氧化铁 -糖复合物的有效治疗量是指铁的含量按重量计为氢氧 化铁-糖复合物重量的 1-20%,优选为 5-10%,氢氧化铁-糖复合物的剂量 范围为 500mg-4g, 优选 1-3 g, 更优选为 1.5-2g。
在制备本发明的组合物时,添加剂如氯化钠在合成氢氧化铁-糖复合 物之前加入到反应混合物中或在合成氢氧化铁 -糖复合物期间加入,在反 应完成后, 不需分离杂质, 可以将含有反应产物氢氧化铁-糖复合物的反 应混合物直接进行冷冻干燥或喷雾干燥, 优选喷雾干燥。
本发明的药物组合物中的添加剂如氯化钠的用量根据如下方程 I计 算得到。

本发明的另一目的是提供一种适用于人或动物注射给药的氢氧化铁
-糖类复合物的制备方法, 该方法主要包含以下步骤:
至少一种糖或糖的衍生物或它们的混合物与在 OH-离子存在下的 Fe(III)离子和无机氯化物接触。 这里所谓接触是指混合在一起进行化学 反应或不起化学反应。 本方法的反应物在水性介质中发生反应。 本发明 的方法所说的 Fe(m)离子优选以氢氧化铁的形式存在, 而氢氧化铁可由 含水的碱性溶液与含 Fe(III)离子的溶液混合制备得到。
本发明的方法所说的含水的碱性溶液选自氢氧化钠, 碳酸钠和碳酸 氢钠水溶液, 优选碳酸钠或碳酸氢钠。
根据实际需要, 本发明的方法还可进一步包括将未反应的氯化钠连 同反应产物, 如氢氧化铁-蔗糖复合物一起干燥形成最终产物, 即为粉末 组合物。
在本发明的方法中氯化钠的用量根据上述方程 I计算得到。
本发明的再一目的是提供一种适用于人或动物肠道外给药的铁-糖 类复合物的制备方法, 该方法主要包含如下步骤:
a)接触
i ) 至少一种糖或糖的衍生物或它们的混合物, 与
ii ) OH'离子存在下的 Fe(III)离子,
b)加入氯化钠; 和 C) 干燥包含铁 -糖类复合物的最终反应混合物, 使其成为粉末形 式。
本方法的反应在水性介质中完成, 其中的 Fe(m)离子优选以氢氧化 铁的形式存在, 而氢氧化铁通过含水的碱性溶液与含 Fe(III)离子的溶液 混合制备得到, 其中含水的碱性溶液选自氢氧化钠, 碳酸钠和碳酸氢钠 水溶液, 优选碳酸钠或碳酸氢 ¾。 本方法的最终反应混合物通过冻千法 或喷雾干燥法干燥, 优选喷雾干燥法。 喷雾干燥过程中空气温度大约为 70° C到 100° C, 其中空气的进料速度大约在 30Hz到 50Hz之间, 空 气进入喷雾干燥室前空气的预清洁应达到 100,000级规定, 物料的进料 速度大约在 1Hz到 3Hz之间。 本方法中加入的氯化钠与反应产物, 如氢 氧化铁-蔗糖复合物一起干燥形成干燥粉末制品,所得到的粉末能在给药 之前在适当的溶剂中迅速地复溶。 本方法中氯化钠的用量根据上述方程 I计算得到。
在本发明描述的制备粉末状且混有合适辅料的活性补血药成分 (铁 糖复合物)的方法中, "铁" 离子不仅指溶液中的铁离子, 亦指诸如与羟 基基团复合等其他形式存在的铁离子。 类似地, OPT包括氢氧化铁沉淀 物中的 OH_。
"复合物"指分子、铁与某种糖的复合体或聚合体。 "辅料"指任何 无补血活性的分子、 组分、 化合物和复合物。 因此, 广义上的辅料包括 未反应的起始原料、 副产物、 降解产物、 緩冲剂、 稀释剂、 防腐剂以及 盐等。亦可将辅料加入反应混合物中以调节最终产物的化学和 /或物理性 质。 此类辅料亦可称 "添加剂" 或 "赋形剂"。
本发明的铁 -糖类复合物可能由糖或其衍生物形成的骨架结构与铁 结合所组成。 本发明的方法可用于制备粉末状的铁 -糖复合物。有用的试 剂至少应包含一种糖以及能提供三价铁离子来源的物质。
本发明所说的 "糖"指单糖和低聚糖。 "单糖"指之间无配糖键的单 一糖单位。 包括醛糖, 双 糖, 醛酮糖, 酮糖及双酮糖, 还有脱氧糖和 氨基糖, 以及它们的衍生物。 例如单糖的例子包括二羟基丙酮,甘油醛, 赤藓糖, 核糖, 山梨糖, 戊酪糖, 阿拉伯糖, 左旋糖, 半乳糖和 manose 等。 "低聚糖"指十个以内的单糖结合在一起的糖。低聚糖包括但不局限 于蔗糖, 麦芽糖、 纤维二糖、 异麦芽糖、 龙胆二糖、 蜜二糖、 芸香糖、 樱草糖、 海藻糖、 乳糖和它们的衍生物。 优选的是蔗糖。
"糖衍生物" 指由该单糖或低聚糖衍生的化合物。 包括一个或多个 末端基团被氧化成羧基、 叛基被还原、 一个或多个羟基被氢、 氨基、 硫 氢基等取代的糖。 例如氧化糖包括由葡萄糖氧化得到的葡萄糖酸盐。 基 于它们的电离常数和 pKa值, 这些被氧化的糖基可以离子化。 离子化的 糖被称为蔗糖盐或糖酸, 其质子仍留存在离子化的糖上。 若离子化的羧 基与阳离子如钠离子结合, 就形成了糖酸盐。 其他适合的糖或糖的衍生 物包括那些与上述糖类性质相似的物质。 优选的糖衍生物为葡萄糖酸盐 如葡萄糖酸钠。
对本发明有用的典型糖及其衍生物须可充分溶于水中。 包括 D型和 L型光学异构体的糖或其外消旋混合物在内的自然存在或合成的糖及其 衍生物均适用于本发明。 糖的衍生物可能包括基于糖的酸、 盐、 甲酯、 胺和醇衍生物。 酸包括但不局限于葡萄糖酸、 葡萄糖二酸、羟基酸果糖、 α -曱基酪氨酸、 糖醛酸、 趁糖二酸、 甘露酸、 糖酪酸、 半乳糖醛酸、 葡 萄糖醛酸、 甘露糖醛酸、 木糖酸、 酒石酸、 半乳糖二酸、 甘油酸、 乳酸、 阿拉伯糖二羟酸、 甘露糖二羟酸、 葡萄糖二羟酸、 麦芽糖酸以及乳糖醛 酸。 盐可由糖醛酸和碱金属或碱土金属构成, 这些金属包括但不局限于 锂、 钠、 钾、 铍、 镁、 钙、 锶和钡等。 其中尤其有用的盐为葡萄糖酸钠。 胺包括但不局限于岩藻糖胺(2-氨基 -2,6-二脱氧半乳糖)、 半乳糖胺(2- 氨基 -2-脱氧半乳糖)、 acosamine ( 3-氨基 -2,3,6-三脱氧 -L-木-己糖)、 杆 菌胺(2,4-二氨基-2,4,6-三脱氧-0-葡萄糖) 、 葡萄糖胺(2-氨基 -2-脱氧 葡萄糖)等。 醇包括但不局限于甘露醇、 葡糖醇、 阿拉伯糖醇、 木糖醇、 岩藻糖醇、 鼠李糖醇、 赤藓糖醇、 核醣醇、 半乳糖醇、 丙三醇等。
聚合糖或多糖例如淀粉、纤维素、右旋糖酐和糊精不适用于本发明。 事实上, 本发明的铁-糖类复合物不包含显著数量的多糖。对本发明的目 的而言, "显著数量" 被定义为会引起不良反应的多糖浓度, 例如铁-糖 类复合物通过非胃肠道方式用药于患者时引起的过敏反应。
因此, 本发明所称的铁-糖类复合物优选为铁-蔗糖复合物或葡萄糖 酸铁钠复合物。
制备铁-糖类复合物的反应在水相或实际上为水相的环境中进行较 理想。 "实际上为水相" 意味着反应介质的一部分可以包括非水性液体, 在该程度内生成铁-糖类复合物的反应不会受到明显的影响。 更适宜地, 反应介质几乎全部是水。
该铁离子最好为三价铁离子, 而非二价铁离子。 可溶或可分散的含 三价铁的化合物可被用作 Fe(m)的来源材料。 这些材料包括但不限于氯 化铁、 硝酸铁、 硫酸铁、 碳酸铁、 柠檬酸铁以及氢氧化铁等。 氢氧化铁 对本发明尤为有用, 但上述其他的铁盐可用于制备氢氧化铁。 虽然大部 分铁盐都是可用的, 但以那些微溶于水的铁盐为最好。
氢氧化铁优选为固体沉淀状态或为分散的胶体状态。 胶体由一种被 分成微小颗粒(胶粒) 的物质分散于另一种物质中而构成。 胶体被认为 是一种介于溶液和混悬液之间的物理状态。 氢氧化铁胶粒的大小在 1纳 米到 100纳米的范围内。 "真溶液" 指两种或多种物质的均质混合物。 在 "真溶液" 中, 溶质的粒度近似于分子的大小, 这比胶体或悬浮液的 颗粒粒度要小很多。 基于本发明, "溶液" 所指的范围较宽, 包括真溶 液和胶体以及它们的混合体。 因此, 反应混合物溶液可指混有溶于 "真 溶液" 中的未反应物质的氢氧化铁胶体。
具代表性的, 铁盐的水溶液可用来制备氢氧化铁。 或者, 直接从市 场上购买氢氧化铁。 有多种可水解产生 (OH)-离子的碱或盐可被用来制 备氢氧化铁中间体。 此类碱或盐包括氢氧化钠, 氢氧化钾, 碳酸钠以及 碳酸氢钠。 六水合三氯化铁是 Fe(III)离子的最好来源。 碳酸钠为与铁盐 反应制备氢氧化铁的最好原料。
若通过铁盐与碱或碱性化合物如碳酸钠反应来制备氢氧化铁 , 则可 以固体或溶液的形式混合铁盐与碱或碱性化合物。 最好先将铁盐完全溶 于水中, 再将碳酸钠溶液緩慢滴加到铁盐溶液中。 搅拌 10-30分钟, 即 得氢氧化铁中间体。 该氢氧化铁可直接用于后续与糖的反应中。 将糖以 固体或溶液的形式加入到已分散或呈胶体状态的氢氧化铁中。
基于本发明, 反应最好以离心分离结束, 并用水洗涤, 收集滤饼。 氢氧化铁最好是以水洗, 以利于测定其重量。 测定湿氢氧化铁的含水量 是为了测定氢氧化铁的净重。 在有水存在的情况下, 将固体或溶液形式 的糖与氢氧化铁混合。 滴加一定量的氢氧化钠溶液以调节反应液的 pH 值。 搅拌反应物并緩慢加热以促进溶解。 糖、 水和氢氧化钠的投料量基 于所加氢氧化铁的量计算。
投料比 (w/w ) 为:
氢氧化铁 : 蔗糖 : 氢氧化钠 : 总水 =1: a : b : c
其中:
a为 5-12范围内的任一数字, a在 8-9之间更为可取; b为 0.1-0.3之间的任一数字, b在 0.15-0.25之间更为可取; c为 10-15之间的任一数字, c在 12-13之间更为可取。 氢氧化铁 (干品)的重量 =氢氧化铁中间体的重量 X氢氧化铁中间 体的铁含量 X 106.86/55.84
在本发明中氢氧化铁中间体是指氢氧化铁的湿品 (含水的氢氧化 铁)。
本发明在一实例中的投料比 (w/w ) 为:
氢氧化铁 : 蔗糖 : 氢氧化钠 : 总水 =1 : 8.4906 : 0.2076 : 12.2642 总水包括氢氧化铁中间体的水, 其相当于中间体总重减去氢氧化铁 净重。 总水还包括氢氧化钠溶液和其他溶液中的水。
在所有的成分都已完全溶解后, 应对该溶液取样检测氯和铁含量用 以确定所需加入的氯化钠的重量。 氯化钠的重量通过下式计算得到 方程 I:
G 反应液 = G 总水 + ( 蔗糖 + G〗 + G 氢 化钠― G 馏出水
G 补氯 == G 反应波 x 58.5 X (C 反应液饮 X 1.06%- C 反应液氣) /35·5, G 反应液: 反应液总量 G 总水: 溶配总水量;
G «: 蔗糖投料量 G,: 氢氧化铁投料量
G 氢氧化钠投料量 G it水: 取样时馏出水净重
G ^: 补加氯化钠量 C 反应液 反应液铁含量(% )
C 反应液氯含量(%) ,
所述量均以重量计。
氯化钠的加入量是依据上述计算公式得到的。
总的反应混合物被过滤, 同时滤液在 100°C至 120°C得以蒸馏。蒸馏 罐的温度和反应混合物的浊点都应被监控。 当浊点到达一设定值, 即 4.6-5.1之间任一值时, 停止蒸馏。 当反应混合物还艮热的时候加入少量 的水。 搅动反应混合物然后检测其溶液比重。 如果其比重在 1.35 g/ml 以上, 再加水直到溶液比重在 1.25-1.35 g/ml之间。 制得的铁-蔗糖溶液 经冷却后待干燥。
在干燥前不必移出未反应的反应物或反应副产物。 同时也可使用其 他的干燥方法干燥最终产物,最终的铁 -蔗糖溶液用喷雾干燥法干燥更为 可取。 压缩空气和热空气的预清洁应达到 100,000级的标准。 在干燥过 程中, 干燥器中的物料应成流化状。 流化的液体先通过蠕动移液泵, 然 后通过压缩空气雾化成极细的液滴, 再通过喷雾器喷射进入干燥器。 热 空气也用来促进干燥。
干燥参数如下: 物料输入速度在 l-3Hz之间。 空气温度大约为 70。C 到 100。C。 物料温度大约为 50。C到 75。C。 空气输入速度为 30-50Hz。
干燥后的物料经冷却后称重。最好把干燥的铁-蔗糖复合物粉碎再通 过 40 目筛。 过筛后的复合物最好再混合以得到均匀的铁-蔗糖复合物粉 末。 把干燥粉末状的复合物装入到具两层的 PE袋中, 然后密封。 把密 封好的 PE袋放入到铝塑复合袋中密封, 再放入到铝听中, 密封, 贴签。 千燥的铁-蔗糖复合物可以包装成 10kg, 5kg, lkg, 500g, 250g, 50g的 规格, 或者按照顾客的需要进行包装。 提供的化学制品,化合物和投料量的范围只是作为一个大体的指导。 例如, 这里所用的糖类中的蔗糖其目的仅仅是为了便于阐述。 本领域技 术人员有可能找出其他类似的化学制品或范围, 这些化学制品或范围能 在不偏离本发明实质的情况下完成该生产过程。 具体实施方式
