The name "Otsuka" translates to "major milestone". Indeed, Otsuka's people - healthcare professionals, scientists, researchers, sales and marketing professionals, and others - have achieved many major milestones while maintaining a commitment to address unmet medical needs, improve health and enhance the quality of human life worldwide.

The roots of Otsuka America Pharmaceutical, Inc. (OAPI) go back to the original factory established in Japan by Mr. Busaburo Otsuka in 1921. The business grew and diversified considerably over the following decades, investing in local enterprises and establishing corporations in 17 countries and regions around the world. Now Otsuka Pharmaceutical Co., Ltd. (OPC) is one of the largest healthcare companies in Japan.

Otsuka established its first U.S. healthcare-related business--Maryland Research Laboratories (now Otsuka Maryland Medicinal Laboratories OMML)--in Rockville, Maryland in 1985. The business was expanded to become Maryland Office of Clinical Research, and finally it was incorporated as Otsuka America Pharmaceutical, Inc. in 1989.

In May 1999, OAPI launched PLETAL®(cilostazol) Tablets1, an Otsuka-developed treatment for intermittent claudication, in the U.S. OAPI was responsible for sales, manufacturing, marketing, and other endeavors related to the product. OAPI also launched ABILIFY® (aripiprazole) Tablets2 in November 2002. ABILIFY is an Otsuka-discovered compound for the treatment of schizophrenia and acute manic and mixed episodes associated with Bipolar I Disorder. OAPI is co-promoting the product with Bristol-Myers Squibb (BMS). In 2004 Otsuka entered into co-promotion alliance with Santarus, Inc. to co-promote ZEGERID®  (omeprazole/sodium bicarbonate)3.

In January 2001, the research and clinical development functions, which constituted a significant part of Otsuka America Pharmaceutical, Inc., became Otsuka Maryland Research Institute (OMRI), a company focused on the research and clinical development of new healthcare products, as well as basic research. OMRI was part of a larger global clinical development effort by Otsuka Pharmaceutical Co. Ltd., which established Centers of Excellence to focus on specific areas of medicine.

In January 2007, Otsuka Pharmaceutical Development & Commercialization (OPDC) was formed by merging two Otsuka organizations – Otsuka Maryland Research Institute, Inc., (OMRI) and Otsuka’s Global Development & Commercialization Division (GD& C).  OPDC is a globally focused organization that plays a leadership role in the research and development of Otsuka’s ethical, innovative healthcare products and ensures full integration of development and commercialization activities. OPDC strategically develops drug candidates from initial discovery of a compound through life cycle management, preparing a plan that will lead to ultimate global registration, marketing, and the full life cycle of the product.  It conducts high-quality clinical studies in diversified therapeutic areas and is the cornerstone of Otsuka’s global drug development and strategic commercial planning efforts.

OPDC is dedicated to improving patients’ health by developing novel healthcare products that address unmet medical needs.  It continuously strives to offer new treatment options to patients worldwide through collaborative activities between its global and local pharmaceutical businesses.  Its experienced physicians, scientists, researchers, marketing and other business professionals have a commitment to the growth of the Otsuka organization, by continually building on the experience, wisdom and knowledge gained from past and present activities that cover the full continuum of a product’s development and ongoing existence.
