Problems solved by technology

As a body surface drug, such as Chinese Patent No. 02150093.2 and Chinese Patent No. 0310044.X invented recombinant human granulocyte macrophage colony-stimulating factor gel, which mainly treats skin burns, scalds and ulcers on the skin or mucous membranes, but the gel It stays in the affected part of the skin for a short time and is easy to be removed. Especially for oral medicine, the gel is easily diluted by saliva and cannot achieve the good effect of treating oral ulcers.

Abstract

An oral sticking sheet of the recombinant human granulocyte-macrophage colony stimulating factor for treating oral ulcer is composed of a water-insoluble protecting layer and an adhesive layer containing said active medicine, adhesive, the stabilizer for stabilizing the activity of protein and percutaneous absorption promoter.

Description

technical field [0001] The invention relates to an anti-oral ulcer drug recombinant human granulocyte macrophage colony-stimulating factor oral patch and a preparation method thereof. Background technique [0002] Oral ulcer is a kind of common disease, frequently-occurring disease. Its incidence rate accounts for about 15% of the total cases in dental clinics. There are many reasons for oral ulcers, such as low autoimmunity; vitamin deficiency; individual wound healing barriers; various viruses invade the oral cavity; low levels of white blood cells in the blood can cause oral ulcers. Though oral ulcer is not serious disease, because the patient has in every age group, and the course of disease is long, is difficult to cure, affects diet and even conversation, so majority of patients hope to have a kind of easy to use, the drug dosage form of good curative effect. [0003] At present, there are several kinds of medicines for the treatment of oral ulcers. Traditional Chine...
