Fabrication of Electrospun Mucoadhesive Membranes for Therapeutic Applications in Oral Medicine
2017
Oral mucosal lesions are related to several etiologies, including trauma, infection, and immunologic and neoplastic diseases. Their prevalence varies greatly depending on ethnicity, gender, and exposure to risk factors. Currently, most oral mucosal lesions are treated with creams, mouthwashes, or gels containing suitable drugs. However, topical medications may be relatively ineffective as they are removed rapidly from oral surfaces, limiting drug contact times. Systemic medications might be more effective but are associated with unacceptable off-target side effects. The aim of this study was to produce novel polymeric mucoadhesive membranes for therapeutic applications on the oral mucosa using electrospinning. Poly(vinylpyrrolidone) (PVP) and Eudragit RS100 (RS100) were used for the fabrication of membranes, whereas dextran (Dex) or poly(ethylene oxide) (PEO) particles were incorporated to enhance their mucoadhesive properties. An electrospun poly(caprolactone) (PCL) backing layer (BL) was added to create...
