Aiming to further expand its contribution to patients in China, Eisai has been working to establish the new Suzhou plant as the plant with the largest production capacity under the Eisai Group on a new industrial site more than five times larger than the former Suzhou plant (oral solid dose production facility scheduled for closure at the end of November 2018) at approximately 134,000m2 in size to further strengthen the stable supply chain as well as improve production efficiency. The new Suzhou plant’s oral solid dose production facility has a production capacity (formulation of approximately 3 billion tablets / packaging for approximately 5 billion tablets per year) which is approximately double that of the former Suzhou plant, and handles the formulation and packaging of oral solid dose products such as Methycobal®, Aricept® and Pariet® for the domestic Chinese market. In addition, ECI established a parenteral facility (production capacity: 60 million bottles per year) in advance in November 2014, where it manufactures the injection formulation of Methycobal.


Eisai’s business operations in China are one of its core businesses which is third-largest in scale after Japan and the United States. With the full-scale commencement of operations at the new Suzhou plant, Eisai seeks to strengthen its in-house domestic production system in China and expand its stable supply chain of high quality pharmaceuticals, contributing to increasing the benefits to patients and their families in China.
