Patient Medication Information: uses, side effects, how to take - Teva-Donepezil
ABOUT THIS MEDICATION
What the medication is used for:
This medicine is called TEVA-DONEPEZIL (which contains donepezil hydrochloride).
Donepezil hydrochloride is one of a group of drugs called “cholinesterase inhibitors”
TEVA-DONEPEZIL is used for the symptomatic treatment of mild, moderate, and severe Alzheimer’s disease.
TEVA-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. TEVA-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 TEVA-DONEPEZIL 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.
