OLIVE LEAF POLYPHENOLS LOADED MUCOADHESIVE ORAL FILMS

Abstract

Among drug delivery systems, mouth dissolving films (MDFs) are a form of drug administration with many advantages. Some problems could be experienced, primarily in pediatric and geriatric patients with conventional drug delivery methods as swallowing. It is of great convenience to dispensing the drug with a film dispersed in the mouth in such cases. In this study, for the preparation of films, the solvent casting method was preferred. The effect of biopolymer ratio and loaded olive leaf extract on the film properties were investigated with the central composite experimental design. Characterization studies of the prepared films were done with AFM, SEM, and FTIR analysis. Based on the characterization studies, the four best formulations were chosen, and further investigations were focused on these formulations. Formulation 8 was chosen as the optimum formulation among 17 formulations due to its better film properties as flexibility and homogeneity, lower disintegration time 200s, and a higher antioxidant capacity 3.21 mM TEAC/g MDF. The obtained data revealed that it is possible to deliver olive leaf polyphenols with the prepared mouth dissolving films.
