Donepezil EP Impurity D with CAS No: 4803-57-0 is an impurity standard of Donepezil. Donepezil is a medication used in the treatment of Alzheimers disease and other forms of dementia. Structurally, it is a reversible inhibitor of acetylcholinesterase, an enzyme that breaks down acetylcholine in the brain. By inhibiting this enzyme, donepezil increases the concentration of acetylcholine in the brain, enhancing cholinergic neurotransmission and temporarily improving cognitive function. Administered orally, donepezil is often part of a comprehensive approach to managing the symptoms of Alzheimers disease, providing some relief in terms of memory and cognitive abilities. Its mechanism of action highlights the importance of cholinergic deficits in Alzheimers disease and the role of acetylcholinesterase inhibitors in symptomatic treatment.
