Teikoku Seiyaku and Eisai Co., Ltd. announced in early 2009 that the companies signed agreements regarding the development and marketing of the Aricept Patch in Japan, the U.S., and rest of world. If approved in the U.S., Eisai Inc. will hold marketing rights in the U.S. and will co-promote the Aricept Patch with Pfizer.

About Aricept (donepezil HCl)

Aricept is the first and only prescription medication approved by the FDA for the treatment of all stages of AD—mild, moderate and severe dementia of the Alzheimer's type. It is not a cure for AD, but Aricept may help provide symptomatic benefits for some patients. Aricept may work differently for each person. For those who respond, symptoms may improve, they may stabilize, or they may progress more slowly than without Aricept. Aricept is currently available in 5 mg tablet, 10 mg tablet and 23 mg tablet, as well as an orally disintegrating tablet (5 mg and 10 mg). Aricept is co-promoted in the United States by Eisai Inc. and Pfizer Inc.


ARICEPT may not be for everyone. People at risk for stomach ulcers or who take certain other medicines should tell their doctors because serious stomach problems, such as bleeding, may get worse.

People at risk for certain heart conditions should tell their doctor before starting ARICEPT because they may experience fainting. People with serious lung conditions and difficulty breathing, bladder problems or seizures should tell their doctor before using ARICEPT. ARICEPT 23 mg is associated with weight loss. Check with the doctor if this is a concern. Inform the doctor if the patient needs surgery requiring anesthesia while taking ARICEPT.

Some people may have nausea, diarrhea, difficulty sleeping, vomiting or muscle cramps. Incidence of nausea and vomiting were markedly greater in patients taking ARICEPT 23 mg/day versus patients taking ARICEPT 10 mg/day. Some people may feel tired or may have loss of appetite. If they persist, please talk to the doctor.
