Alzheimer's disease is the most serious neurodegenerative disorder characterized by cognitive and memorial defects alongside deterioration in behavioral, thinking and social skills. Donepezil hydrochloride (DPZ) is one of the current two FDA-approved cholinesterase inhibitors used for the management of Alzheimer's disease. The current study aimed to formulate hyaluronic acid-coated transfersomes containing DPZ (DPZ-HA-TFS) for brain delivery through the intranasal pathway to surpass its oral-correlated GIT side effects. DPZ-HA-TFS were produced using a thin film hydration method and optimized with a 24 factorial design. The influence of formulation parameters on vesicle diameter, entrapment, cumulative release after 8 h, and ex vivo nasal diffusion after 24 h was studied. The optimal formulation was then evaluated for morphology, stability, histopathology and in vivo biodistribution studies. The optimized DPZ-HA-TFS formulation elicited an acceptable vesicle size (227.5 nm) with 75.83% entrapment efficiency, 37.94% cumulative release after 8 h, 547.49 µg/cm2 permeated through nasal mucosa after 24 h and adequate stability. Histopathological analysis revealed that the formulated DPZ-HA-TFS was nontoxic and tolerable for intranasal delivery. Intranasally administered DPZ-HA-TFS manifested significantly superior values for drug targeting index (5.08), drug targeting efficiency (508.25%) and direct nose-to-brain transport percentage (80.32%). DPZ-HA-TFS might be deemed as a promising intranasal nano-cargo for DPZ cerebral delivery to tackle Alzheimer's disease safely, steadily and in a non-invasive long-term pattern.
