Pharmaceutical composition for treating periodontitis, and preparation method and application thereof

Abstract

The invention relates to a pharmaceutical composition for treating periodontitis and a preparation method thereof, wherein the pharmaceutical composition comprises chlorhexidine or derivatives thereof, poloxamer 407, a release speed adjusting agent, a stabilizer and other additives. The pharmaceutical composition has particular physical characteristics; when the temperature reaches the gel point, the composition can undergo phase transition from liquid to semisolid gel; the composition is liquid at the room temperature; after being used, the composition changes into semisolid gel quickly under the human body temperature condition and then is adhered on the surface of periodontal mucosa to release the medicine, thus a therapeutic effect is obtained; the composition has specific controlled-release property, and can achieve a controlled-release effect of 4 to 5 days of sustained medicine release by adjusting types and dosages of the release speed adjusting agents, thereby reducing the medicine using times, and improving the medication compliance of patients; and the composition is good in stability, and convenient to produce, transport and store.

Description

technical field

[0001] The invention relates to the technical field of pharmaceutical preparations, in particular to a pharmaceutical composition for treating periodontitis and a preparation method thereof. Background technique

[0002] Periodontitis is the "number one killer" of oral health, and some early symptoms of periodontitis have also become the main feature of the deterioration of oral "sub-health". Periodontitis is a chronic inflammation that invades the gums and periodontal tissues. It is a destructive disease. Its main features are the formation of periodontal pockets and inflammation of the pocket walls, alveolar bone resorption and gradual loosening of teeth. It is the leading cause of adult Leading cause of tooth loss. The disease is mostly caused by bacterial plaque, calculus, food impaction, bad restorations, bite trauma, etc. The gums are inflamed and swollen, and the plaque accumulation is aggravated at the same time, and spread from supragingival to subg...
