Who We Are

At our core is perseverance–a fierce determination to overcome any obstacle, regardless of setbacks, on behalf of patients, caregivers, and their loved ones. We will not be bound by doing what’s been done before. Instead, we free ourselves from preconceived notions to discover solutions that advance patient care. Our mission is clear. Otsuka-people: creating new products for better health worldwide.

Our Focus

Neuroscience

Our driving philosophy at Otsuka is to serve those with unmet medical needs, and that couldn’t be more true than in our dedication to the central nervous system (CNS) space. In our 30 years of experience working in this therapeutic area, we continue to innovate and defy limitation by taking risks to overcome the complexities of treating mental health. We respect the value within every mind and are committed to making a difference in the lives of patients living with schizophrenia, major depressive disorder, bipolar disorder, anxiety disorders, and other CNS conditions.

Nephrology

Recognizing a critical gap in clinical expertise and research within nephrology, Otsuka took the initiative to pioneer advancements. For decades, we have dedicated ourselves to driving innovation in this field and in others with significant unmet needs. Our commitment remains steadfast in developing groundbreaking therapeutics in nephrology and other areas, revolutionizing treatment possibilities. Through Otsuka’s commitment to enduring perseverance, we have achieved significant breakthroughs, offering renewed hope to patients and expanding treatment options for clinicians, and we will continue to do so.

Our Legacy

The first Otsuka US research and development base was established in Rockville, Maryland. Just a few years later, in 1989, Otsuka’s first US commercial organization was created, Otsuka America Pharmaceutical, Inc (OAPI).

2002

Otsuka’s second US location, in Princeton, New Jersey, was opened. We continued our evolution, and in 2007 Otsuka Pharmaceutical Development & Commercialization, Inc (OPDC), was created to oversee all commercial pharmaceutical and medical device activities in the United States.

Today the two companies, OAPI and OPDC, are part of one family—the Otsuka Holdings Co, Ltd, that has over 180 companies, with more than 45,000 employees in 28 countries around the world.
