Application status and prospects of topical drug therapy in oral mucosal diseases
Abstract
Oral mucosal disease is a general term for a type of disease that mainly affects the oral mucosa and surrounding soft tissues. In the treatment of oral mucosal diseases, due to the particularity of the anatomical location, the use of topical administration is relatively simple and convenient; drugs can easily accumulate in the lesions, and at the same time, they can also avoid adverse reactions caused by systemic drug delivery. Topical administration has become an important and even preferred option for the treatment of oral mucosal diseases. There are various types of topically used drugs for oral mucosal diseases, such as glucocorticoids (triamcinolone acetonide), immunomodulatory drugs (tacrolimus), antiseptic drugs (chlorhexidine), pain relievers (lidocaine) and proprietary Chinese medicines (aloe vera gel). Among these drugs, although the most widely used liquid formulations such as gargles and sprays are easy to use, they are not conducive to local retention of drugs due to the particularity of the oral environment and function. Based on this, researchers have continuously improved the dosage form of the drug, and developed a series of semi-solid pharmaceutical preparations such as gels and ointments, some of which have exerted good curative effects in clinical work. In addition, although films, patches and other solid oral mucosal topical pharmaceutical preparations have few clinical applications, they have also been widely researched and described and are expected to become the mainstream dosage form in the future. In general, with the improvement of dosage forms, topical administration is playing an increasingly important role in the treatment of oral mucosal diseases. Therefore, combined with basic research and clinical reports, this article reviews the application of topical drug delivery in the treatment of oral mucosal diseases.
