Exploring nanoparticular platform in delivery of repurposed drug for Alzheimer’s disease: current approaches and future perspectives

Introduction Alzheimer's disease (AD) stands as significant challenge in realm of neurodegenerative disorder. It is characterized by gradual decline in cognitive function and memory loss. It has already expanded its prevalence to 55 million people worldwide and is expected to rise significantly. Unfortunately, there exists a limited therapeutic option that would mitigate its progression. Repurposing existing drugs and employing nanoparticle as delivery agent presents a potential solution to address the intricate pathology of AD.
