What the medication is used for
This medicine is called ACH-Donepezil (which contains
donepezil hydrochloride).
Donepezil hydrochloride is one of a group of drugs called
“cholinesterase inhibitors”
ACH-Donepezil is used for the symptomatic treatment of
mild, moderate, and severe Alzheimer’s disease.
ACH-Donepezil can only be obtained with a prescription
from a doctor.
What it does
In the brains of persons with Alzheimer’s disease, there is
a decrease in the function of a neurotransmitter system
which uses acetylcholine as its chemical messenger. ACH-Donepezil acts by inhibiting an enzyme called
acetylcholinesterase, leading to an increase in the level of
acetylcholine in the brain, which may help relieve the
symptoms of Alzheimer’s disease.
In clinical studies, patients treated with donepezil
hydrochloride showed improvement, remained unchanged,
or declined more slowly as compared to patients who
received a placebo (sugar tablet). Benefits were seen in
memory and other mental functions, as well as in the
ability to perform daily activities. ACH-Donepezil may
take as long as 12 weeks to begin working and patient
response to this medicine will vary.
