Our history spans over 100 years, beginning with the incorporation of F.E. Zuellig Inc. in 1922 in the Philippines.

In 1938, Zuellig organized a Drug Department to specialize in the importation and marketing of pharmaceuticals and other healthcare products in the region.

By 1953, the Pharma Industries, Inc. was incorporated to provide contract manufacturing services to pharmaceutical companies in the Philippines.

In 1974, the Zuellig Group launched a pharmaceutical contract manufacturing plant in Thailand, named F.E. Zuellig (Bangkok) Ltd., which later rebranded as Interthai Pharmaceutical Manufacturing Ltd. in 1998.

For nearly 50 years, we have been a trusted partner to over 35 pharmaceutical companies, including most of the leading multinationals, whose products are not only sold in Thailand, but exported across South East Asia, Japan, USA and Canada.

We take pride in our numerous awards, certifications and site accreditations, which ensure our mutual success.
