  • Description

    Bioactive donepezil (Aricept, Donepezilo) is a potent, reversible, specific, and non-competitive acetylcholinesterase (AChE) inhibitor for the treatment of mild to moderate dementia.

    In vitro studies have shown that donepezil exhibits reversible, non-competitive inhibition of AChE. Its selectivity for AChE is 500-1000 times higher than that for BuChE. Short-term and long-term exposure to human SH-SY5Y neuroblastoma cells induces concentration-dependent inhibition of cell proliferation, independent of muscarinic or nicotinic receptor blockade and apoptosis. Donepezil reduces the number of cells in the S-G2/M phase of the cell cycle, increases the number in the G0/G1 phase, and reduces the expression of two cyclins, cyclin E and cyclin B, during the G1/S and G2/M transitions. Simultaneously, it increases the expression of the cell cycle repressor p21. In addition, donepezil can increase action potential-dependent dopamine release and regulate nicotinic receptors in dopaminergic neurons of the substantia nigra. In vivo studies show that donepezil is slowly absorbed from the gastrointestinal tract, with a terminal half-life of 50-70 hours in young volunteers and greater than 100 hours in older adults. After extensive hepatic metabolism, the plasma protein binding rate of the parent compound is 93%. Donepezil is metabolized in the liver via the cytochrome P450 system (CYP1A2-, CYP2D6-, CYP3A4-related enzymes). In animals, donepezil remains unchanged in the brain, and no metabolites were found in neural tissue. In plasma, urine, and bile, most donepezil metabolites are O-glucuronides. After oral ingestion, peak plasma concentrations are reached within 3-5 hours, and its absorption is not affected by food. Donepezil exhibits linear pharmacokinetics within the concentration range of 1-10 mg/day. 96% of circulating donepezil is protein-bound. Uses donepezil hydrochloride monohydrate is a centrally acting, reversible acetylcholinesterase inhibitor.

    ChEBI: Donepezil is a centrally acting reversible acetyl cholinesterase inhibitor. Its main therapeutic use is in the treatment of Alzheimer's disease where it is used to increase cortical acetylcholine.Donepezil, (±)-2,3-dihydro-5,6-dimethoxy-2-[[1-(phenylmethyl)-4-piperidinyl]methyl]-1H-inden-1-one (Aricept), commonly referred to in the literature asE2020, is a reversible inhibitor of AChE.

    Donepezil is a racemate comprising equimolar amounts of (R)- and (S)-donepezil. A centrally acting reversible acetylcholinesterase inhibitor, its main therapeutic use is in the treatment of Alzheimer's disease where it is used to increase cortical acetylcholine. It has a role as an EC 3.1.1.7 (acetylcholinesterase) inhibitor, a nootropic agent and an EC 3.1.1.8 (cholinesterase) inhibitor. It contains a (R)-donepezil and a (S)-donepezil. It is a conjugate base of a donepezil (1+).|In 2016, the global burden of dementia was estimated to be 43.8 million, demonstrating a significant increase from a global prevalence of 20.2 million in 1990. Donepezil, also known as Aricept, is a piperidine derivative acetylcholinesterase inhibitor used in the management of the dementia of Alzheimer's Disease, and in some cases, is used to manage other types of dementia. 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. Though it does not alter the progression of Alzheimer's disease, donepezil is effective in managing the symptoms of its associated dementia.|Donepezil is an oral acetylcholinesterase inhibitor used for therapy of Alzheimer disease. Donepezil is associated with a minimal rate of serum enzyme elevations during therapy and has only rarely been implicated as a cause of clinically apparent liver injury.|An indan and piperidine derivative that acts as a selective and reversible inhibitor of ACETYLCHOLINESTERASE. Donepezil is highly selective for the central nervous system and is used in the management of mild to moderate DEMENTIA in ALZHEIMER DISEASE.
