SAN JOSE, Calif., Sept. 17 /PRNewswire/ -- Teikoku Pharma USA, Inc., an international specialty pharmaceutical company, announced today that the U.S. Food and Drug Administration (FDA) has accepted for review the New Drug Application (NDA) for a new weekly transdermal patch of Aricept®, a leading medication for the treatment of Alzheimer's disease.

The company developed the weekly Aricept(r) patch based on a license agreement executed between Teikoku Pharma USA, Inc. and Eisai Co., Ltd. (Eisai) in February 2009. The acceptance of the NDA indicates that the FDA deems the company's submission to be sufficient to review. The NDA was submitted to the FDA by Teikoku Pharma USA, Inc. on June 30, 2010.

The Aricept® transdermal patch formulation employs a unique drug delivery system, making it the world's first weekly transdermal patch for the treatment of Alzheimer's disease.
