[1] Headquartered in Bresso, in the Province of Milan, the company has business operations in three continents: Europe, South America and Asia.

The Warehouse distributed basic pharmaceutical products such as bismuth, iodine and bicarbonate, and also other commodities such as liquorice, spices and talcum powder.

Gaetano Zambon provided services for the Military Medical Corps and during this period, partners Teodorico Viero, Silvio Farina and Arrigo Giacomelli expanded the company to include Giovanni Ferrari who also had a background in pharmaceuticals and sales.

The new Zambon plant was opened in September 1946, with the Minister of Foreign Trade, Pietro Campilli in attendance.

Alberto Zambon established good relationships in the United States and with a few large multinationals existing at that time, especially in the field of research, so that the company could develop its own pharmaceuticals rather than licensing them.

Zambon SA was established in Barcelona, Spain, in 1960 to serve the Iberian Peninsula (an independent Portuguese headquarters was opened in Lisbon, in 1992).

In 1961, Alberto Zambon moved the main headquarters and research laboratories to Bresso, Milan, while the production facility remained in Vicenza.

In 1983, Zambon bought out Emilio Ghirardi’s company Simes and production was moved to a new plant in Vicenza in 1984.

In 1996, the Shantou Shanning Zambon Chemicals Ltd (Equity Joint Venture) was founded and its plant was opened a year later.

At the same time, Zambon entered the central nervous system therapy area with the molecule safinamide.
