The path of protecting human health
and life
The mission of all pharmaceutical companies and employees
is to fight disease and protect those who suffer or
lose their lives. Therefore, the development, production and
supply of excellent pharmaceuticals are a fundamental
responsibility of pharmaceutical companies.
Expansion from active pharmaceutical ingredient to drug product and development of advanced biopharmaceuticals
Since our foundation in 1955, our company has been practicing its mission and meaning as greatest values. In the 1950s, when there were virtually no domestic producers of Active Pharmaceutical Ingredient, REYON accumulated its own production technology to produce drug substances and finished drugs under the banner of localization of drug substances, and now, based on R&D and cooperative R&D in various fields, we are challenging the development and commercialization of the state-of-the-art biopharmaceuticals.

Continuing the work of the late Chairman Seong-Rak Yoo, who devoted his entire life to growth as a pharmaceutical company that investigates the principles of life, all of REYON's executives and employees are striving day by day to make the company a leader in the innovation of the pharmaceutical industry of the future based on the company's technology and experience accumulated for over 65 years since establishment.
Sublime Philosophy,
the Future of the Pharmaceutical Industry
“A company that investigates the principles of life” REYON Pharmaceutical promises to continue all of its efforts to pave the way to a healthy future for mankind while maintaining the noble ideology and sense of mission from the time of its founding. On behalf of all employees, I would like to express my deepest gratitude to everyone who supports REYON Pharmaceutical, and kindly ask for your unchanging support and encouragement.
Thank you.
