Question

There is a drug on the market called Aricept (Donepezil) used for cognitive loss associated with Alzheimer's. What is it's mechanism of action and how effective is it? Answers: A. It inhibits the breakdown of acetylcholine; effective in improving cognition but only for a short period of time. B. It's an agonist at NMDA receptors; quite effective in enhancing cognitive abilities over a long period of time. C. It's a neuromodulator for nitric oxide; enhances the oxygenation of the brain thus improving cognitive functions. D. It enhances the production of acetylcholine, improves spatial memory but not necessarily object recognition. E. None of the above as Aricept is not used for Alzheimer's, it's used for Parkinson's.
