摘要:

背景:口腔溃疡是由多种原因引起的口腔黏膜常见病,常以局部用药的治疗为主,口腔溃疡膜的应用可以将药物直接作用于溃疡创面,溃疡膜的缓释设计延长了药物的作用时间,使局部的药物浓度明显增高,有利于药效的发挥。
目的:探讨口腔溃疡膜材料及口腔溃疡载药膜材料的制备方法以及检测指标。
方法:口腔溃疡膜可以通过持续的黏附于溃疡创面,阻隔口腔唾液及口腔菌群对溃疡创面的侵蚀,起到阻碍细菌及保护创面的作用。口腔溃疡载药膜材料可分为合成高分子成膜材料和天然高分子聚合物成膜材料。常用于制备口腔溃疡膜的材料有聚乙烯醇、羟丙基甲基纤维素、羧甲基纤维素等。
结果与结论:壳聚糖口腔溃疡膜具有抗菌、抗氧化的作用,同时可以止血、消炎,促进溃疡组织愈合的作用。壳聚糖和中药载药膜材料可以使溃疡面积明显缩小,壳聚糖膜在治疗有效率方面明显高于抗生素膜。口腔溃疡载药膜制备的过程中,常用高效液相色谱法测定药物浓度,通过线性关系、回收率试验、黏附力和黏附时间的测量,分析溃疡载药膜材料作用后局部的药物浓度、作用时间以及黏附情况。

Abstract:

BACKGROUND: Oral ulcer is a common disease in the oral mucosa caused by a variety of reasons, which is often treated with local administration. The application of oral ulcer film can apply the drugs directly on the ulcer wounds, and the
sustained-release design of the ulcer films can prolong the action duration of the drugs and significantly increase the local drugconcentration, which is conducive to playing the drug’s efficacy.
OBJECTIVE: To explore the preparation method and detection index of membrane materials and drug loading membrane materials used for the treatment of oral ulcers.
METHODS: Membranes for mouth ulcers can be continuously adhered onto the ulcer wounds and then block the erosion of saliva and oral flora to ulcer wounds, which play a role in preventing the bacteria against the wound. The drug loading membrane materials can be divided into synthetic polymer materials and natural polymer materials. Materials commonly used in the preparation of mouth ulcer membranes include polyvinyl alcohol, hydroxypropyl methyl cellulose, carboxymethyl cellulose.
RESULTS AND CONCLUSION: Chitosan membranes for mouth ulcers have the advantages of anti-bacteria, anti-oxidation, bleeding, and anti-inflammation, thereby promoting healing of ulcer tissue. The chitosan and Chinese herb loading membrane materials can significantly reduce the ulcer area, and the effect of chitosan membrane is better than that of antibiotics membrane. During the preparation of drug loading membranes for mouth ulcers, high-performance liquid chromatographic method is the commonly used method to detect the drug concentration. The local drug concentration, action time and adhesion are analyzed through the detection of linear relationship, recovery test, adhesion and adhesion time.
