Our Story
Our story begins during the Second Industrial Revolution, when Frederick E. Zuellig established a Drug Department in the Philippines in 1938, specializing in the trade, marketing, and distribution of healthcare products.
After the Second World War, the founder’s two sons, Dr. Stephen and Gilbert diversified the business and went beyond the traditional trading activities and added the contract manufacturing services where Pharmaceutical Industries (Pharma Industries) was formed in 1953.
