The History of PReMA

PReMA’s commitment to Thailand can be traced to the reign of King Rama V. PReMA members were present in Thailand when the pharmaceutical industry was in its infancy; playing important roles in leading the manufacturing and the promotion of innovative medicines to provide access to the Thai people of high quality and highly effective medicines while promoting ethical practices among all its members.

Starting as the PPA

Over 100 years ago, pharmaceutical companies began establishing their offices along the Chao Phraya River during the time of King Rama V. Siriraj Hospital was the first to introduce Thailand to the practice of modern medicine. Since then, PReMA members have been contributing to the kingdom’s health care. With the rise in popularity of new medical treatments; of modern practices in medicine, of equipment and of knowledge. Companies in the pharmaceutical industry began discussing the possibility of an organization to represent the industry and to act as a vehicle for cooperation with the government on several issues in the industry.

Finally, Henry R. Koczyk of the International Pharmaceuticals Ltd. and Leonard Chan from Pfizer International set the wheels in motion with the establishment of the Pharmaceutical Products Association (PPA) on 9 July 1970. 15 years later, the name was changed to The Pharmaceutical Producers Association.


On the 29th September 2004, the Pharmaceutical Producers Association or PPA became PReMA (the Pharmaceutical Research and Manufacturers’ Association).

The rationale for the transformation is the growing role of PReMA’s members in research and development in innovative medicines for thr promotion of a healthier life for the people and the patients.

Research and development in innovative medicines is a continuous process in the evolution of treatment for diseases. Each year, huge investments are made in research and development to create innovative medicines with ever higher quality and greater safety for human use.
