Abstract

The invention discloses a medicinal gel for chronic periodontitis and a preparation method and application thereof. The medicinal gel comprises a carrier, traditional Chinese medicine ingredients, water and β-sodium glycerophosphate; the carrier is made of N-methyl-2-pyrrolidone , triacetin, polylactic acid-glycolic acid copolymer mixed, Chinese medicine ingredients include salvia, gall, Bletilla striata, astragalus, coptis and cinnamon extracts. The volume fraction of traditional Chinese medicine ingredients in the gel is 15%, β-sodium glycerophosphate is 4%, water is 30%, the mass fraction of polylactic acid-glycolic acid copolymer is 40%, N-methyl-2-pyrrolidone and triglyceride The volume ratio of glycerol acetate is 5:5. The invention also provides the preparation method and application of the medicinal gel. The gel of the invention is relatively simple and convenient to prepare, has good biocompatibility and adhesion, good local administration and absorption, few adverse reactions, and also has the advantages of traditional Chinese medicine ingredients, high efficiency, no toxic side effects, convenient use and moderate price. .

Description

technical field

[0001] The present invention relates to a medicinal gel for auxiliary treatment of chronic periodontitis, a preparation method and application thereof, in particular to a medicinal gel of Jiawei Wudan Powder for chronic periodontitis, preparation method and application thereof . Background technique

[0002] Chronic periodontitis is a chronic infectious disease. It is a multifactorial disease determined by bacteria, host and environment. The interaction between microorganisms and the host determines the process and progression of the disease. The antigenic components of plaque bacteria and the toxins and enzymes produced by them can directly cause the destruction of periodontal tissue, and can also trigger host immune responses and inflammatory responses, and indirectly cause the destruction of periodontal tissue and other systemic lesions in the body. The host's immune response in the early stage can protect the periodontal tissue and prevent pathogenic bac...

[0063] Example 2: Validation of Jiawei Wudan Powder medicinal gel for chronic periodontitis.

[0064] The modified Wudan powder gel group in the treatment group and the tetracycline gel group in the control group completed the following treatments based on the periodontal basic treatment. see figure 1 shown.

[0065] Grouping and treatment of subjects: 100 patients with chronic periodontitis, aged 18-80 years old, male or female, were randomly divided into traditional Chinese medicine gel group A and western medicine gel by random number table method on the basis of standardized SPR. Group B, 50 cases in each group, group A was given adjuvant treatment with periodontal local modified Wudan powder gel, and group B was given local adjuvant treatment with tetracycline sustained-release gel, both of which were administered once a week, one week as a course of treatment, and comparison after 4 courses of treatment 2 groups of treatment effects.
