Donepezil was first approved by the FDA in 1996, and its extended-release form was approved in combination with [Memantine] in 2014 to manage moderate and severe forms of Alzheimer's dementia. A donepezil transdermal delivery system, Adlarity, was approved by the FDA in March 2022 for the treatment of Alzheimer's dementia.
