Donepezil Hydrochloride is classified as a cholinesterase inhibitor, primarily used as a cognitive enhancer.
Mechanism of Action:
Donepezil enhances the function of nerve cells in the brain by preventing the breakdown of acetylcholine. Acetylcholine is a neurotransmitter essential for memory and learning, and its levels are significantly lower in patients with Alzheimer's disease. Donepezil works by inhibiting the enzyme acetylcholinesterase, responsible for the degradation of acetylcholine. By blocking this enzyme, donepezil increases the amount of acetylcholine available, thereby improving cholinergic transmission and aiding in cognitive function.
