Donepezil Hydrochloride for Impairment of Memory With Safe Pass

Introduction

ARICEPT (donepezil hydrochloride) is a reversible inhibitor of the enzyme acetylcholinesterase, known chemically as (±)-2, 3-dihydro-5, 6-dimethoxy-2-[[1-(phenylmethyl)-4-piperidinyl]methyl]-1Hinden- 1-one hydrochloride. Donepezil hydrochloride is commonly referred to in the pharmacological literature as E2020. It has an empirical formula of C24H29NO3HCl and a molecular weight of 415.96. Donepezil hydrochloride is a white crystalline powder and is freely soluble in chloroform, soluble in water and in glacial acetic acid, slightly soluble in ethanol and in acetonitrile, and practically insoluble in ethyl acetate and in n-hexane.

Function

Donepezil hydrochloride is a long-acting Alzheimer’s disease (AD) in the symptomatic treatment drugs. AD is a kind of memory loss as the main performance, accompanied by other cognitive impairment of acquired intelligence decline. Nearly 30 years of research show: AD progressive degeneration of cholinergic neurons is memory loss, disorientation, personality changes and behavioral reasons, such cholinergic theory has been confirmed by histological study.

Donepezil hydrochloride is a second-generation cholinesterase (ChE) inhibitor, its therapeutic effect is reversibly inhibiting acid hydrolysis of acetylcholine acetylcholinesterase (AchE) caused by increased content of acetylcholine receptor sites. Donepezil may have other mechanisms, including the disposal of the direct effect of the peptide, neurotransmitter receptors, or Ca2 + channels.
