Description

一种治疗牙周病的中药制剂、 制备方法及应用 技术领域
本发明涉及中药制剂及制备方法, 具体涉及一种治疗牙周病的中药制剂、 制 备方法及应用。 背景技术
牙周病是人类常见多发病, 全世界所有国家, 均无法避免。 我国 35岁以上 成年人发病率高达 98%。 至今, 在世界范围内仍无理想的特效药品。
. 中国中医学认为, "肾主骨, 骨之余为齿"。 当人体肾阴虚损, 则骨失濡养, 牙齿为之疏豁不固,令齿松动,咀嚼无力; 肾虚则胃热,虚火上炎,牙龈红肿疼痛; 脾虚, 则令人全身功能下降, 无力抵御毒邪侵袭, 于此, 则牙周病频繁发作。
现代医学认为, 牙周病病因主要有二个方面, (一) 口腔菌群在内外综合因 素促动下, 产生长消紊乱, 失去相对组比的平衡, 主要致病需氧菌和厌氧菌迅速 大量繁殖, 菌斑大量堆积, 产生大量有毒代谢物和细菌内毒素, 对牙周组织造成 感染; (二) 人体自身免疫功能低下, 失调, 使患者自身无法抑制主要致病菌对 牙周组织的损伤, 出现免疫变态反应和牙周病炎症的各种症状。 发明内容

"齿者, 骨之所终, 髓之所养, 肾实主之, 故肾衰则齿豁, 精盛, 则齿坚。 《成都口腔医院.屈强》, (《四川中医》 11 卷第二期 P.46)。 目前, 治疗牙周病以 清热类药为多。 清热类药 "不但有抑杀细菌, 病毒, 钩端螺旋体, 原虫, 真菌等 作用, 还有中和病毒……, 改善机体反应性"; 其主要有以下几个方面作用: " 1、 抗病原微生物; 2、 抗细菌毒素; 3、 解热 4、 抗炎 5 、 对免疫功能影响; 清热药 还可增强垂体——肾上腺皮质功能"。 (《中国中医药发展五十年》 1999年出版, 孟庆云 .P119-120)。
本发明制剂针对传统清热剂在治疗牙周病中的不足, 在同一制剂中, 注重清 热、 消炎、 凉血、 解毒的同时, 兼顾了滋养肝肾, 补益脾胃。 在提高抑杀致病菌 的同时, 提高了人体对致病菌感染的免疫力, 抑制变态反应。 对人体整体虚实全 面平衡, 短期控制, 改善牙周病症状。 即: 肾主骨, 骨之余为齿, 肾阴虚损, 则 骨失濡养, 牙齿为之疏豁松动, 咀嚼无力; 肾亏虚则胃热, 虚火上炎, 则牙龈红 肿、 疼痛; 脾虚, 则正消邪长, 全身功能降低, 牙周病频繁发作。 首乌, 生地专 入肝肾, 补养真阴, 救孤阳元烈之象; 菟丝子是脾、 肝、 肾三经补益要药, 虚者 可补, 实者可利, 寒者可温, 湿者可燥, 燥者可润, 脾健肝常, 肾气当固, 肾阴 当守, 此三味, 为君药。 生鳖甲, 制芋肉, 潜敛真阳, 止痛, 除热, 消烦, 壮筋 骨, 是以为臣。 地丁草, 穿心莲, 凉血消肿, 清热解毒, 此二味为佐。 甘草, 补 脾益气, 缓急止痛, 清热, 解毒, 调和诸药, 此为使者。 诸药协力, 则滋肾阴, 养肝血, 健脾土, 清泄虚实邪火, 利肝、 凉血, 标本兼治, 相得益彰, 使牙周病 诸症, 迎刃而解。
传统的中药复方制剂的制备方法,采用水提法和醇提法,时间长(6天左右), 温度高(100Ό ), 使有效成分中对热不稳定的物质在提取过程易被氧化, 分解, 聚合,及异构化,而且提取物杂质较多。有许多分子量大的有效成分, 因沸点高, 挥发度小, 采用水提法和醇提法无法得到, 既造成能耗大, 又使有效成分损失, 总的得率偏低, 药材资源浪费, 影响制剂应有疗效。
本发明制备方法中, 对部分药材采取了超临界二氧化碳流体萃取技术, 萃取 温度低(25°C- 45°C左右), 时间短(2-5小时), 能耗省, 无有机溶剂残留, 质量 稳定。 由于超临界二氧化碳流体对部分脂溶性成分具有较强溶解力, 高渗透性和 高传质速率, 无萃取过程中有效成分损失, 且萃取过程中始终处于溶解度非饱和 状态, 避免有效成分发生分解、 氧化、 聚合、 异构化等不良现象发生, 能最大程 度地保持各组分的原有特性, 萃取物香气自然。 同时在高压作用下, 对许多分子 大, 沸点高, 挥发度小的有效物质, 超临界二氧化碳流体能更为有效而完整地抽 提出来, 使得率平均高于传统提取法的 3.5-4倍, 如植物多糖和植物内酯等, 确 保制剂应有的效能, 提高了药品的疗效。
本发明还结合使用固体流浸膏超细粉碎(细度大于 250 目), 改进了人的吸 收能力, 提高了药物的生物利用度。
《牛黄解毒片》是治疗牙周病有针对性的品种,在临床应用中覆盖面积很大, 是公认的清热消炎良剂。
本发明以 《牛黄解毒片》 为对照组, 对本发明制剂进行有关临床验证: 试验组: 本发明制剂, 规格 700mg/片, 剂型: 薄膜异型片。
对照组: 牛黄解毒片, 600mg/片
给药剂量: 700mg*2粒 /次, 3次 /日
给药时间: 7天; 排除服用其他任何药品; 完全一致。
临床症状: 1、 牙龈红肿; 2、 牙龈疼痛; 3、 牙龈出血; 4、 牙齿松动; 5、 咬唇疼痛。
牙周病指数- 牙龈指数 (G1 ); 龈沟出血指数 (SB1 ); 牙周袋深度 (PD); 牙齿松动度 (MD)。
试验结果:
1、 给药前、 后, 实验组 Gl、 SB1、 PD、 MD均有高度显著性(改善) 差异 (P<0.01 ); 对照组 Gl、 SB1有显著 (改善)差异 (Ρ〈0· 01 ), 而 PD、 MD均无 明显差异 (P〉0. 05)。
2、 给药前后临床症状比较
Figure imgf000006_0001
试验结果显示, 本发明制剂在 2— 7天内能有效控制牙周病, 疗效明显好于 牛黄解毒片。
本发明治疗牙周病的中药制剂在清热、 消炎、 凉血、解毒的同时, 兼顾了滋 养肝肾, 补益脾胃, 在提高抑杀致病菌的同时, 提高了人体对致病菌感染的免疫 力, 标本兼治, 疗效显著。 为牙周病的治疗提供了一种疗效确切、 服用方便的新 型药物。 具体实施方式- 实施例 1、 制剂活性成分制备
