Problems solved by technology

The traditional method of topical administration is to directly spray or distribute the drug powder or liquid on the affected part of the oral cavity. The disadvantage is that the drug diffuses in the oral cavity, which not only tastes bitter but also numbs unbearably, which makes the patient feel extremely uncomfortable. Disadvantages such as being washed away by saliva and poor local adhesion will affect the therapeutic effect

Abstract

A medicinal film for treating oral ulcer is composed of a plastics coated paper layer, a composite film layer, and a medicine layer as sandwich which is proportionally prepared from gentamycin sulfate, menonasal and dexamethasone acetate. Its preparing process includes preparing film slurry, preparing medicine slurry defoaming and preparing film.

Description

technical field [0001] The invention relates to a novel medicinal film mainly used for treating oral ulcer wounds, and a preparation method thereof. Background technique [0002] Oral ulcers are a common disease in oral mucosal diseases, and the incidence rate is second only to odontosis. Its pathogenesis is often related to viral infectious diseases or immune dysfunction. The pain caused to the patient is very obvious: periodic attacks, persistent painful erosions. In severe cases, the erosion surface still hurts when the oral cavity is in a static state. For most patients, it takes about 7-12 days for the oral erosions to heal naturally. [0003] In addition to systemic medication for the treatment of oral erosions, topical medication is the preferred treatment option. Most of the topical drugs currently used clinically are hormones or traditional Chinese medicine preparations, such as corticosteroids prednisone, dexamethasone, antibiotics and circulation-promoting dru...
