Definitions
- the present invention relates to the field of pharmaceutical preparations, and in particular to an iodine polymer and glucocorticosteroid combination pharmaceutical composition for treating dermatitis.
- Skin inflammation such as eczema, allergic dermatitis, atopic dermatitis, urticaria (Urticaria), etc. are caused by an allergen causing allergic reactions and causing inflammation of the skin.
- allergic reactions to skin allergies.
- infections such as viruses, fungi and bacteria are one of the important causes of skin inflammation.
- Bacterial infection is an important sensitizing factor in various skin inflammations such as allergic dermatitis.
- Glucocorticoids are widely used to treat skin inflammation, but due to the immunosuppressive effects of glucocorticoids, glucocorticoids can not achieve anti-inflammatory effects when used to treat inflammation caused by bacterial infections on the skin surface. Inflammation is intensifying.
- glucocorticoids it affects the application of glucocorticoids in the treatment of skin inflammation.
- strain dermatitis caused by infections such as bacteria and non-infectious allergic dermatitis are very similar in surface symptoms, and it is difficult to distinguish them without microscopic examination, which is clinically prone to misdiagnosis, thereby delaying treatment.
- glucocorticoids are not used for treatment, sensitization of microorganisms such as bacteria is often accompanied by the occurrence of allergic skin inflammation, and treatment with antibacterial drugs to infection. After elimination, animals often have inflammatory sputum, indicating that skin inflammation is often more difficult to treat than the infection itself.
- Povidone iodine is a complex of polyvinylpyrrolidone (PVP) and iodine, also known as iodophor, containing 9 ⁇ 12% of effective iodine. It is a broad-spectrum strong disinfectant, against viruses. Bacteria, fungi and mold spores have a strong killing effect. It is less irritating to the skin, low in toxicity and long lasting. Safe and easy to use. It is basically non-irritating to tissues and is used for skin and mucous membrane disinfection, such as pre-operative cleaning, surgical site and wound disinfection. The sterilization principle is mainly to release the bactericidal action by releasing free hydrated iodine.
- the povidone is hydrophilic, and is a carrier for transporting iodine to the cell membrane.
- the povidone iodine solution is commonly used at a concentration of 0.1% to 10%.
- the existing povidone iodine preparation agent is mainly povidone iodine gel, suppository, cream, and solution, and the content ranges from 1% to 10% (Chinese Pharmacopoeia 2010 edition).
- Fluticasone propionate is a glucocorticoid drug with potent local anti-inflammatory and anti-allergic effects and good tolerance. Suitable for inflammatory and pruritic skin diseases that can be relieved by various corticosteroids, such as: eczema including specific eczema and discoid eczema; nodular pruritus; psoriasis (except generalized plaque); neuropathic skin disease Including simple moss; lichen planus; seborrheic dermatitis; contact allergy; discoid lupus erythematosus; generalized erythema systemic steroid hormone therapy adjuvant, insect bite dermatitis; For children: Inferior corticosteroids are more than one year old (including one year old) Children can use this product to relieve inflammation and itching caused by specific dermatitis under the guidance of a doctor.
- the existing fluticasone propionate or halomethasone preparations are
- Halomietasone a strong topical glucocorticosteroid containing a halogenated group. It has anti-inflammatory, anti-allergic, systolic and anti-proliferative effects. For many types and different causes of inflammatory skin diseases, it can quickly reduce and eliminate symptoms such as itching. Experimental studies have shown that the multiple pharmacological effects of glucocorticosteroids can be attributed to the complex molecular level mechanisms that interact with specific cytoplasmic receptors.
- Inventor's previous research invented a combination of povidone iodine and corticosteroids for the treatment of ocular diseases (CN200780008873.5) o
- Chinese patent application CN200910228785.7 discloses a povidone containing iodine and cyclodextrin A topical composition comprising a glucocorticoid.
- the patent adopts a cyclodextrin inclusion technique.
- cyclodextrin inclusion technology due to 1, limited inclusion materials, in the preparation process often acetone, ethanol and other organic easily lead to strong hematological and injurious nephrotoxicity, is not conducive to human health. 2.
- the molecular size and polarity of the encapsulated drug There are restrictions on the structure and structure. Because the size, polarity and structure of glucocorticoids are different, the cyclodextrin inclusion technique is not universal. 3. In vitro and in vivo stability of the inclusion complex: The stability in vitro depends on the polarity of the host and guest molecules and the strength of the intermolecular force; the drug can be replaced by competitive replacement in the body, resulting in rapid drug release. 4. The encapsulation efficiency of cyclodextrin inclusion is not high, which leads to an increase in the difficulty of the process. 5. The inclusion of cyclodextrin has an unknown effect on the release of the drug. For example, the release rate may not reach the effective concentration of the drug to be maintained due to insufficient release. So finding a way to effectively address this limitation is a very important issue. Summary of the invention

Description
治疗皮炎的碘聚合物和糖皮质类固醇复方药物组合物 技术领域
本发明涉及药物制剂领域, 具体涉及一种治疗皮炎的碘聚合物和糖皮质类固醇复方药物 组合物。
背景技术
皮肤炎症如湿疹 ( eczema )、 变应性皮炎 (allergic dermatitis )、 特应性皮炎 (atopic dermatitis ) 荨麻疹 (Urticaria) 等都是由某种变应原引起变态反应而造成皮肤炎症, 弓 I起皮 肤变态反应的变应原有多种, 其中病毒、真菌、 细菌等感染是引起皮肤炎症的重要原因之一, 细菌感染是变应性皮炎等多种皮肤炎症中重要的致敏因素。 糖皮质类激素广泛用于治疗皮肤 炎症, 但是由于糖皮质类激素的免疫抑制作用, 使得糖皮质类激素在用于治疗皮肤表面细菌 感染造成的炎症时不但不能达到抗炎的效果, 反而会使炎症加剧。 影响了糖皮质类激素在治 疗皮肤炎症时的应用。 况且由于细菌等感染造成的应变性皮炎和非感染性的变应性皮炎在表 面症状上十分相似, 如不采用显微镜检验很难分辨, 因次在临床上容易造成误诊, 从而延误 治疗。 而对于皮肤细菌等感染造成的皮肤病, 虽然在治疗上不使用糖皮质类激素, 但由于细 菌等微生物的致敏性, 往往伴随有变应性皮肤炎症的发生, 采用抗细菌药物治疗至感染消除 后, 动物往往还有炎性痂存在, 说明皮肤炎症往往比感染本身更难于治疗。
聚维酮碘 (PVP-L 简称 Pi) 是聚乙烯吡咯烷酮 (PVP ) 与碘的复合物, 又称碘伏, 含有 效碘 9〜12%, 是一种广谱的强力杀菌消毒剂, 对病毒、 细菌、 真菌及霉菌孢子都有较强的杀 灭作用。 对皮肤刺激性小, 毒性低, 作用持久。 使用安全、 简便。 对组织基本无刺激性, 用 于皮肤及粘膜消毒, 如手术前清洗、 手术部位及伤口消毒。 其杀菌原理主要是通过释放游离 水合碘发挥杀菌作用, 聚维酮具有亲水性, 是将碘输送至细胞膜的载体, 当复合物接触到细 胞壁后, 释放出的游离碘和菌体蛋白的氨基酸结合, 使其变性, 同时氧化细菌原浆蛋白的活 性基团而使微生物迅速死亡。 聚维酮碘溶液常见的使用浓度为 0.1%〜10%。 现有聚维酮碘制 剂主要为聚维酮碘凝胶剂、 栓剂、 乳膏剂、 溶液剂, 含量 1%〜10%不等 (中国药典 2010版)。
丙酸氟替卡松 (fluticasone propionate) 为糖皮质激素类药物, 具有强效的局部抗炎与抗 过敏作用、 有较好的耐受性。 适用于各种皮质激素可缓解的炎症性和瘙痒性皮肤病, 如: 湿 疹包括特异性湿疹和盘状湿疹; 结节性痒疹; 银屑病 (泛发斑块型除外); 神经性皮肤病包括 单纯性苔藓; 扁平苔藓; 脂溢性皮炎; 接触性过敏; 盘形红斑狼疮; 泛发性红斑全身类固醇 激素治疗的辅助用药, 虫咬皮炎; 粟疹。 对于儿童: 低效皮质激素无效的一岁以上 (含一岁) 儿童在医生的指导下可用本品缓解特异性皮炎引起的炎症和瘙痒。 现有丙酸氟替卡松或卤米 松制剂主要为乳膏剂、 溶液剂、 鼻喷雾剂。 含量 0.1%〜1%不等。
卤米松 (Halometasone), 卤米松是一个含卤基的强效外用糖皮质类固醇药物。 它具有抗 炎、 抗过敏、 收縮血管和抗增生作用。 对于很多类型和不同原因的炎症性皮肤病, 它能很迅 速地减轻和消除, 例如瘙痒等症状。 实验研究结果表明, 糖皮质类固醇的多种药效作用可归 因于它与特殊的细胞质受体相互作用所致的复杂的分子水平的机理。
发明人前期研究中发明了聚维酮碘和皮质激素的复方制剂, 用于眼部疾病的治疗 (CN200780008873.5 )o 中国专利申请 CN200910228785.7公开了一种含有聚维酮碘与环糊精 包合糖皮质激素的局部外用组合物。为了克服药物的不稳定, 该专利采取了环糊精包合技术。 众所周知, 环糊精包合技术由于 1、 包合材料有限, 在制备过程中常有丙酮、 乙醇等有机容 易造成较强的血液毒性和损伤性肾毒性, 不利于人体健康。 2、 对包合药物的分子大小、 极性
和结构等有限制, 由于糖皮质激素分子大小、 极性、 结构都不相同, 所以环糊精包合技术不 带有普遍性。 3、包合物的体内外稳定性: 体外稳定性取决于主客分子之间的极性和分子间力 的强弱; 体内可经竞争置换将药物取代, 导致药物快速释放。 4、 环糊精包合的包封率不高, 导致加大了在工艺过程难度。 5、 环糊精包合后对药物的释放存在未知的影响, 如释放度, 可 能会由于释放的不充分导致达不到需要维持的药物的有效浓度。 因此找到一个能够有效解决 该局限性的方法是一个非常重要的问题。 发明内容

6、 判断结果:
从实验结果可以看出,采用本发明聚维酮碘和卤米松的复方组合物实验组与基质阴性对照 组相比, 豚鼠背部红肿情况亦明显好转; 血清中溶菌酶的含量显著增加; 病理组织学观察结 果显示, 与乳膏基质阴性对照组的上皮层和真皮层比较(见图 15、 16), 卤米松复方乳膏制剂 对皮肤表面被覆鳞状上皮小灶状变性、 坏死, 部分区域痂皮脱落的症状有很大改善, 皮肤表 面被覆鳞状上皮基本完整 (见图 1、 3 ), 真皮层内小灶状化脓性病灶减轻 (见图 2、 4); 卤米 松复方乳膏制剂对豚鼠金黄色葡萄球菌感染皮炎有较显著的治疗作用。 聚维酮碘和丙酸氟替 卡松的复方组合物实验组与基质阴性对照组相比, 豚鼠背部红肿情况明显好转; 血清中溶菌 酶的含量显著增加; 病理组织学观察结果显示, 与乳膏基质阴性对照组的上皮层和真皮层比 较 (见图 15、 16), 丙氟酸氟替卡松复方乳膏制剂组对皮肤表面被覆鳞状上皮小灶状变性、 坏死, 部分区域痂皮脱落的症状有很大改善, 皮肤表面被覆鳞状上皮基本完整 (见图 5、 7), 真皮层内小灶状化脓性病灶减轻 (见图 6、 8 ); 丙酸氟替卡松复方乳膏制剂对豚鼠金黄色葡 萄球菌感染皮炎有一定的治疗作用。 与聚维酮碘乳膏、 糖皮质激素卤米松乳膏和丙酸氟替卡 松乳膏的拆方组相比, 复方组的豚鼠背部红肿情况明显好转; 血清中溶菌酶含量显著增加; 病理组织学观察结果显示, 与聚维酮碘乳膏、 糖皮质激素卤米松乳膏和丙酸氟替卡松乳膏的 拆方组相比 (见图 9、 10、 11、 12、 13、 14) , 聚维酮碘和丙酸氟替卡松或卤米松组合的复 方制剂组对皮肤表面被覆鳞状上皮小灶状变性、 坏死, 部分区域痂皮脱落的症状有较大的改 善 (见图 1、 3、 5、 7), 真皮层内小灶状化脓性病灶减轻 (见图 2、 4、 6、 8 ) ; 红霉素软膏 阳性对照组, 皮肤表面被覆鳞状上皮尚完整, 真皮层内见小灶状化脓性病灶, 真皮浅层内毛 囊等附属器尚完整 (见图 17、 18), 聚维酮碘和丙酸氟替卡松或卤米松组合的复方制剂组疗 效优于各拆方组, 复方药物产生了协同作用。 众所周知, 由于碘分子和糖皮质化学反应的高电位, 碘和碘释放碘载体和大多数糖皮质 是不能相容的。 我们通过适当加入微量的碘酸钾, 有效抑制聚维酮碘分解保持低浓度的稳定 性, 而且降低了碘酸钾有可能产生的毒副作用。 制备时我们优选采用匀质及微粉化技术, 对 溶解性不好的糖皮质激素具有普遍适用性, 工艺操作简单, 质量可控, 不影响皮质激素的正 常释药速度, 不改变其正常疗效。 避免了单独使用糖皮质激素或聚维酮碘时变态反应造成的 症状消除慢的特点, 也克服了糖皮质激素不能应用于细菌感染所造成的皮肤炎症, 免疫能力 的下降导致二次感染风险的缺点, 提高了疗效的同时, 也扩大了使用范围, 降低了误诊的发 生率。 稳定性试验表明, 本发明复方制剂不需要添加苯扎氯铵、 咪唑啉基脲及其他有毒的防 腐剂, 无需添加其他物质来延长储存时间。
试验方法: 每组取 7支试验药物, 在 40°C±2°C, 相对湿度 75%±5%的情况下进行稳定性试验。 分别于 0天、 5天、 10天时取样进行检验, 每次 2支。 进行性状、 pH值、 有效碘含量的检测。 有效碘含量, 采用滴定法测量, 将每支试验样品移取 110克左右至 250ml的烧杯中, 用纯化水 充分溶解, 直到没有完全溶解, 用 0.01N硫代硫酸钠溶液滴定至褐色消失, 确定所用硫代硫酸 钠的体积, 计算有效碘。
