Otsuka Pharmaceutical Factory

In addition to IV solutions, our core product domain and a fundamental pillar of medical treatment, and medical foods, we engage in R&D to develop products which create new value by meeting unmet needs in the fields of surgical aid and regenerative medicine products. We see things from the patient's point of view and develop innovative medical products which are not bound by the constraints of existing concepts, and undertake all these initiatives with enthusiasm and a sense of duty. For example, we are developing a product to prevent adhesions, a common cause of abdominal pain and intestinal obstruction after operations, and a bioengineered pancreatic islet product which could become a major treatment for diabetes patients.
