A kind of compound oral ulcer patch and preparation method thereof

Abstract

The invention relates to a compound oral ulcer patch and a preparation method thereof, comprising a muscle-generating layer, a slow-release layer and a heat-clearing and antibacterial layer, and the muscle-generating layer includes a film-forming material, a plasticizer, a solvent softener, and a muscle-generating drug , the slow-release layer includes a film-forming material, a plasticizer and a softener, and the heat-clearing and antibacterial layer includes a film-forming material, a sustained-release component, and a heat-clearing and antibacterial drug component. The invention adopts a three-layer composite structure, the myogenic layer is in contact with the ulcer site, and mainly adopts muscle-inducing drugs to promote rapid muscle growth and repair of the ulcer; the heat-clearing and antibacterial layer mainly uses heat-clearing and antibacterial drugs for clearing away heat and killing Bacteria mainly provide a good environment for the recovery of ulcers. The slow-release layer uses bletilla striata polysaccharide or chitosan, which mainly prevents the saliva from dissolving the myogenic layer after the heat-clearing and antibacterial layer is dissolved. The three-layer structure can effectively improve the oral environment and at the same time make the ulcer site recover quickly.

Description

technical field [0001] The invention relates to a compound oral ulcer patch and a preparation method thereof, belonging to the technical field of medicine. Background technique [0002] Oral ulcer, also known as recurrent oral ulcer, aphtha, etc., is a common oral mucosal disease with spontaneous and recurrent. Ulcers are often found in buccal mucosa, lip mucosa, tongue and other parts. They are round or oval ulcers with obvious edges. The ulcer surface is covered with light yellowish white or grayish yellow cellulose derivatives. Two to 48 hours after the ulcer occurred, a characteristic prodromal burning sensation appeared, which seriously affected the patient's eating. The etiology of oral ulcers is complex, resulting in the diversity and uncertainty of its treatment methods. Clinically, symptomatic treatment is mostly used, usually from reducing inflammation, relieving pain, preventing ulcer surface deterioration, preventing secondary infection, and promoting healing. ...
