Net sales of the pharmaceuticals business
- The Accounting Standard for Revenue Recognition, etc. has been applied since FY2021 (resulting in year-on-year growth of 11.3%).
Tsumura’s prescription Kampo formulations were added to the National Health Insurance (NHI) drug price list in 1976, for the first time in its history. Then, the market for our products began to grow, particularly driven by a Kampo boom led by safety-conscious consumers and an increasing number of hospitals adopting our Kampo formulations, including Shosaikoto, a medication for treating chronic hepatitis. Net sales of pharmaceuticals peaked in 1991, posting more than 100 billion yen, out of which 30 billion yen was related to Shosaikoto.
After this, however, net sales began to decline, due to factors such as the market launch of Interferon for chronic hepatitis treatment, and a report on side effects caused by Shosaikoto administered for chronic hepatitis. The downward trend accelerated in 1996, when the media reported on serious side effect cases, including fatal ones, shocking news that undermined the established reputation of Kampo medicines for safety.
In response to this situation, the Company revamped its sales strategies. We created strategies aimed at promoting Kampo medicine itself. As a result, after bottoming out in 1999 net sales have been on a recovery track. Sales growth has been rising particularly since FY2004, backed by the launch of a Kampo drug-fostering program based on accumulated evidence.
