Otsuka Pharmaceutical

Otsuka Pharmaceutical, the pharmaceutical and medical devices subsidiary of Otsuka Holdings Co., headquartered in Tokyo, is a global healthcare company with a distinctive focus on areas of unmet medical need, including psychiatry, neurology, oncology, and nephrology. Its best-known product is aripiprazole (Abilify), one of the most-prescribed atypical antipsychotics globally. Otsuka's research culture emphasises exploring unconventional scientific hypotheses, and the company funds a network of Otsuka Medical Research scholars across Asia, Europe, and the United States. The company developed the world's first digital medicine — aripiprazole with an embedded ingestible sensor — in collaboration with Proteus Digital Health. Otsuka maintains active academic partnerships in nutritional science, renal tubular physiology (tolvaptan for ADPKD), and CNS drug discovery.
