含海藻糖和透明质酸的烧伤
用药传递系统及其制备方法 技术领域
本发明涉及一种烧伤用药传递系统及其制备方法, 更具体地 说,本发明的烧伤用药传递系统中含有透明质酸和 /或透明质酸可 药用盐以及烧伤用药可接受的常规药剂辅料。 背景技术
烧伤(burn )是指由热能、化学物质、 电能以及放射线等所致的 组织损伤, 主要指皮肤、 黏膜、 软组织, 深部包括骨骼、 内脏等的 损伤。 其中热能, 包括热液(水、 汤、 油等) 、 蒸气、 高温气体、 火焰、 炽热金属等所引起的损害, 称为热伤 (thermal injury ) ; 而将热液和蒸气所致的热伤, 称为烫伤(scald ), 故烧伤包括热伤 (含烫伤)、化学烧伤 ( chemical burn )、 电烧伤 ( electr ic burn ) 和放射性烧伤 ( rat iat ion burn ) 。 烧伤在人们生活中极为常见, 据估计, 我国烧伤年发病率约为 2%, 即每年约有 2000多万人遭受 不同程度的烧伤。 烧伤严重威胁着人类的健康, 其可破坏皮肤屏障 功能, 除引起局部组织结构损伤外, 同时还导致局部代谢和功能等 一系列的变化, 如局部变性、 坏死组织产生多种蛋白酶和炎性介质 等物质可引起创面感染、 体液外渗、 引发败血症、 休克等, 甚至危 及生命。 不仅如此, 创面愈合后的瘢痕还给患者带来了心理上和精 神上的痛苦。
因此,人们对防治烧伤的产品给予了很大的希望。 目前临床上治 疗烧伤的局部外用药物有多种, 主要是抗菌的外用药, 诸如金属盐 类、 抗生素类及磺胺类制剂等。 但这些药物存在^ f艮多不足, 例如药 物不能快速緩解疼痛、 药物刺激性大、 不良反应大、 对预后瘢痕束 手无策等, 另外, 创面的干燥常导致结痂的形成, 严重影响药物的 吸收, 甚至加重病情。 例如: 0. 5%的硝酸银在创面湿敷, 可緩解疼 痛, 但不能穿透结痂; 1%硝酸嘧啶银乳骨可少量渗入结痂, 但易引 起白细胞降低等不良反应。 使药物在发挥疗效的同时, 尽可能避免 上述不足的最可行的解决办法就是创新烧伤用药的传递系统 ( del ivery sys tem ) , 使传递系统同时具备以下特点: 一方面能从 根本上提高创面细胞的抗干燥能力, 使创面始终保持新鲜和生理性 湿润、 利于药物的吸收和药效的发挥; 另一方面能緩解疼痛、 减少 感染、 加速创面愈合、 减少瘢痕形成等。 目前的烧伤用药传递系统 多局限于如何提高药物的吸收上, 还没有很好的办法同时解决上述 问题。 发明内容

海藻糖(英文: trehalose )广泛存在于整个生物界, 包括细 菌、 真菌、 昆虫、 其它植物及动物, 其对生物分子有特殊的保护 作用:
抗干燥特性( "水替代" 作用): 海藻糖是一种在脱水作用中 起关键保护作用的双糖, 它能使许多生物在异常条件下, 如高温、 脱水、 冷冻、 干燥时仍能保持原有活性, 提高细胞的抗干燥能力。 而实验中的透明质酸和纤维素醚类化合物等均未表现出抗干燥的 特性。
稳定生物膜的作用: 人的皮肤、 细胞膜等均为生物膜, 海藻糖 可通过降低相变温度, 使在脱水条件下的膜脂仍处于液晶状态, 从 而起到保护生物膜的作用。
对蛋白质等生物分子的保护作用: 海藻糖对脱水干燥的生命物 质有明显的保护作用, 即使在极度干燥等恶劣环境中, 其还能很好 地稳定蛋白质等生物分子, 使其不受破坏。
制剂稳定剂和保鲜剂的作用: 海藻糖作为制剂稳定剂和保鲜剂 已有广泛应用, 这是其它糖类物质所不能比拟的。
由上可以看出, 海藻糖可进入细胞内, 直接作用于细胞, 发挥 其独特的水替代应激因子作用, 提高细胞的抗干燥、 抗冷冻等恶劣 环境的能力, 从而提高细胞适应环境的能力, 保持细胞的新鲜与活 力; 可维持生物膜、 蛋白质等生物分子及受损组织的稳定, 减轻药 物对创面组织的毒性及全身毒性; 可作为制剂的稳定剂和产品的保 鲜剂, 用以延长保质期; 具有良好的生物相容性等。
透明质酸(英文: hyaluronic acid, 又称玻璃酸)天然存在 于人体, 透明质酸多以其钠盐即透明质酸钠 (英文: sodium hyaluronate ) 的形式存在和应用。 本发明所涉及的透明质酸, 包 括透明质酸的盐, 即透明质酸钠或其它透明质酸的盐。 透明质酸基 本为一化学惰性物质, 其具有独特的黏弹性和非牛顿流体的特性, 并具有重要的药理作用和生理功能:
智能保湿作用: 透明质酸被称为理想的天然保湿因子, 其分子 中的羧基和其它极性基团可以与水形成氢键而结合大量的水。 而 且, 透明质酸还可根据环境的湿度, 自动调节吸水量。 这种智能保 湿作用可使创面保持适宜湿度。
润滑作用: 透明质酸溶液具有良好的黏弹性, 在低撞击频率即 低切变速率下, 溶液呈黏性, 可减少组织间的摩擦, 在高撞击频率 即高切变速率下, 溶液呈弹性, 可避免组织损伤。
修复、 促进愈合作用: 透明质酸是创伤无瘢痕修复中不可或缺 的物质, 其可抑制炎症反应, 加速愈合, 修复损伤。
增黏作用: 在一定范围内药物的生物利用度与药液的黏度呈正 相关, 保持适当的黏度是药物发挥高效作用的重要前提。 透明质酸 作为天然的生物大分子黏多糖, 可提高制剂的黏度, 从而延长药物 在创面的存留时间。
生物黏附性: 透明质酸与其它高分子聚合物相比, 相同的溶液 黏度甚至较低的黏度却能使药物获得较高的生物利用度,其原因在 于透明质酸与黏蛋白相互作用、 生物黏附, 从而延緩药物的消除。
铺展润湿能力: 透明质酸作为一种黏多糖, 在增加药物黏度的 同时, 还可使药液在创面均匀地铺展, 增强药物的作用。
緩幹作用: 透明质酸具有使药物緩幹的作用, 是由其分子特异 性所决定的。 药物可通过非共价键方式镶嵌在透明质酸的大分子网 状结构中, 透明质酸分子犹如一个动态的分子筛, 连同药物较长时 间附着于创面。
緩解疼痛作用: 透明质酸可掩盖疼痛受体, 緩解创面部位的疼 痛。
由上可以看出: 透明质酸是人体固有的一种成份, 其可作用于 细胞间隙和结締组织, 提高补水、 保湿、 润滑等作用, 改善细胞的 生存环境, 可使创面组织始终保持生理性湿润; 具有抗炎和緩解疼 痛的作用; 可通过其增黏、 生物黏附、 铺展润湿、 緩#作用和良好 的生物相容性, 延长 ¾物在创面的存留时间, 提高药物的生物利用 度, 减小药物的毒副作用, 降低药物的刺激性等。
本发明传递系统不添加其它活性成份, 其基本构成也可直接用 于烧伤的治疗及减少愈后瘢痕的形成等。
本发明海藻糖是指任何来源的海藻糖, 包括由植物、 动物组 织提取分离而得、 微生物发酵而得及基因工程制备而得, 等。 本 发明海藻糖是指任何存在形式的海藻糖, 包括不含结晶水的海藻 糖和含结晶水的海藻糖, 等。
本发明透明质酸是指任何来源的透明廣酸, 包括由动物组织 提取分离而得、 微生物发酵而得及基因工程制备而得, 等。 本发 明透明质酸包括透明质酸及其盐如: 透明质酸钠 (又称透明质酸 钠) 、 透明质酸锌(又称透明质酸辞) 等。 本发明透明质酸是指 任何相对分子质量大小的透明质酸。 除非特别指明本文中所述的 透明质酸包括透明质酸和 /或其可药用盐。
