Donepezil Hydrochloride

Overview

Basic Info

SummaryDonepezil, a minuscule molecular compound, functions as an acetylcholinesterase inhibitor, indicating that it hinders the degradation of acetylcholine, a neurotransmitter in the brain, and provides assistance in enhancing cognitive function. Patients in mild, moderate, and severe stages of Alzheimer's Disease receive this drug as a therapeutic agent. Initially authorized in November 1996 by Eisai, a pharmaceutical establishment situated in Japan, it has now expanded to a worldwide availability. Although Donepezil Hydrochloride does not hold the cure for Alzheimer's Disease, it does assist in controlling some of the symptoms associated with the disease, such as memory loss, confusion, and other cognitive impairments. As a crucial medication for those existing with Alzheimer's Disease, it can amplify their quality of life and curtail the progression of the disease.
