Abstract:

BACKGROUND: Oral ulcer is a common disease in the oral mucosa caused by a variety of reasons, which is often treated with local administration. The application of oral ulcer film can apply the drugs directly on the ulcer wounds, and the
sustained-release design of the ulcer films can prolong the action duration of the drugs and significantly increase the local drugconcentration, which is conducive to playing the drug’s efficacy.
OBJECTIVE: To explore the preparation method and detection index of membrane materials and drug loading membrane materials used for the treatment of oral ulcers.
METHODS: Membranes for mouth ulcers can be continuously adhered onto the ulcer wounds and then block the erosion of saliva and oral flora to ulcer wounds, which play a role in preventing the bacteria against the wound. The drug loading membrane materials can be divided into synthetic polymer materials and natural polymer materials. Materials commonly used in the preparation of mouth ulcer membranes include polyvinyl alcohol, hydroxypropyl methyl cellulose, carboxymethyl cellulose.
RESULTS AND CONCLUSION: Chitosan membranes for mouth ulcers have the advantages of anti-bacteria, anti-oxidation, bleeding, and anti-inflammation, thereby promoting healing of ulcer tissue. The chitosan and Chinese herb loading membrane materials can significantly reduce the ulcer area, and the effect of chitosan membrane is better than that of antibiotics membrane. During the preparation of drug loading membranes for mouth ulcers, high-performance liquid chromatographic method is the commonly used method to detect the drug concentration. The local drug concentration, action time and adhesion are analyzed through the detection of linear relationship, recovery test, adhesion and adhesion time.
