Abstract
Background: Recurrent aphthous ulcer (RAU) is one of the most common ulcerative diseases of the oral mucosa which is recurrent, painful and slow to heal. Treatment is primarily for pain relief and promotion of healing to shorten the disease duration or reduce the rate of recurrence.
Objective: Development of a new design of topical buccal bilayer mucoadhesive films containing sodium alginate and gellan gum loaded with low dose of 1 mg prednisolone sodium phosphate to reduce the treatment period and decrease side effects of systemic treatment.
Methods: Films were prepared by solvent casting technique and evaluated to ensure optimum film characteristics, and in vivo efficiency.
Results: The bilayer films were thin, flexible with good water uptake, mucoadhesive and mechanical properties. In vitro drug release was sustained and showed anomalous non-Fickian kinetics. SEM confirmed the development of bilayer formation. Fourier Transform Infrared Spectroscopy and Differential Scanning Calorimetery indicated no chemical interaction between the layers. In vivo study in rabbits with induced oral ulceration showed complete ulcer healing within 4-5 days by once daily treatment of the studied film. Histological examination indicated no inflammation on treatment sites compared to inflamed tissue on the control sites.
Conclusion: The results suggested that buccal application of the developed bilayer mucoadhesive films loaded with only 1mg of prednisolone provided mucoadhesive and convenient application and was able to promote RAU healing with shorter treatment duration.
Keywords: Bilayer film, buccal, mucoadhesive, prednisolone, recurrent aphthous ulcer.

Emerging Nanotherapeutics for Mitigation of Neurodegenerative Disorders
Conditions affecting the central nervous system (CNS) present a significant hurdle due to limited access of both treatments and diagnostic tools for the brain. The blood-brain barrier (BBB) acts as a barrier, restricting the passage of molecules from the bloodstream into the brain. The most formidable challenge facing scientists is ...read more
Nanotechnology Based Chemotherapy for the treatment of Head & Neck Cancer
The escalating recurrence rates observed in Head and Neck cancer, particularly within the chemo-therapeutically treated cohort (50-60%), can be attributed to the non-selective nature of current anticancer drug delivery modalities. In this context, nanotechnology-based drug delivery systems emerge as a promising avenue for achieving precise localization of therapeutic agents to ...read more
