Abstract

The invention discloses an oral cavity external preparation. The preparation is a composite film composed of a back bottom layer, a slow-release layer and a quick-release layer. The back bottom layer is a film prepared from ethyl cellulose. The slow-release layer is a film prepared from mixed glue formed by mixing traditional Chinese medicine extracts, porous starch, chitosan, sodium alginate, polyving acohol, borneol, honey and purified water according to a certain mass ratio. The quick-release layer is a film prepared from mixed glue formed by mixing traditional Chinese medicine extracts, porous starch, borax, carbomer, peppermint oil and purified water according to a mass ratio. Meanwhile, the invention further discloses a preparation method of the preparation. By means of the unique formula of the traditional Chinese medicine extracts and scientific design of the dosage form film layers, troubles of existing oral cavity preparations are effectively solved, and the oral cavity external preparation takes effect quickly, is good in slow-release performance, has the effects of relieving swelling and pain and dispersing blood stasis and dredging collaterals and has the unique treatment effect of treating both symptoms and causes of periodontal diseases.

Description

technical field [0001] The invention relates to the field of oral medicine, in particular to an external preparation for treating oral cavity and a preparation method thereof. Background technique [0002] Periodontal disease refers to chronic, nonspecific, infectious diseases that occur in tooth supporting tissues including gingiva, periodontal ligament, alveolar bone and cementum. According to the different parts of the disease invasion, it is mainly divided into: gingivitis and periodontitis. Gingivitis is characterized by red, swollen gums that bleed when brushing or probing. And periodontal inflammation is not only located in the gums, but also involves deeper periodontal tissues, such as the heel connective tissue, periodontal ligament and supporting alveolar bone. In addition, wisdom tooth swelling and pain are also common periodontal diseases. It is estimated that the incidence of periodontal disease in developed countries is about 50%, while that in developing co...
